what is the average page requirement for a doctoral dissertation

How long is a PhD dissertation? [Data by field]

The final piece of the PhD journey is the PhD dissertation. It takes many years to accumulate enough original and new data to fill out a dissertation to the satisfaction of experts in your field. Interestingly, the PhD dissertation length and content vary significantly based on the field you are studying and the publishing conventions.

A PhD can be anywhere from 50 pages to over 450 pages long. This equates to between about 20,000 words to 100,000 words. Most PhD theses are between 60,000 and 80,000 words long excluding contents, citations and references.

A PhD thesis contains different sections including an introduction, methods, results and discussion, conclusions, further work, and references. Each one of these different sections will vary in length depending on the field of study and your particular topic.

Ultimately, a PhD dissertation should contain as many pages and words as it takes to communicate the results of your multi-year investigation.

It is very rewarding to see your thesis come together as you are writing day after day. When I was writing my PhD dissertation I wrote the sections separately and my heart filled with joy when I finally put them all together and compile them into a single PDF document.

Counting the pages should not be the way to determine a PhD dissertation’s value but it certainly helps when your thesis is starting to look substantial in thickness.

How many pages should a PhD dissertation be?

A PhD dissertation should contain as many pages and words as it takes to outline the current state of your field and provide adequate background information, present your results, and provide confidence in your conclusions. A PhD dissertation will also contain figures, graphs, schematics, and other large pictorial items that can easily inflate the page count.

Here is a boxplot summary of many different fields of study and the number of pages of a typical PhD dissertation in the field. It has been created by Marcus Beck from all of the dissertations at the University of Minnesota.

Typically, the mathematical sciences, economics, and biostatistics theses and dissertations tend to be shorter because they rely on mathematical formulas to provide proof of their results rather than diagrams and long explanations.

On the other end of the scale, English, communication studies, political science, history and anthropology are often the largest theses in terms of pages and word count because of the number of words it takes to provide proof and depth of their results.

At the end of the day, it is important that your thesis gets signed off by your review committee and other experts in the field. Your supervisor will be the main judge of whether or not your dissertation is capable of satisfying the requirements of a PhD in your field.

Can a PhD dissertation be too long?

A PhD thesis should contain enough evidence and discussion to report on the most significant findings of your PhD research.

A PhD dissertation should not contain everything that you have done during your PhD. It should only include the data and information required to convince your PhD examining body that wraps up and tells the full story of particular lines of investigation.

Including random results, thoughts, or superfluous explanation can result in a dissertation that is unfocused. I have heard of music PhD is being described as too verbose and physical sciences PhD dissertations as being unfocused.

Therefore, a PhD thesis can be too long if the information it contains does not form a full and cohesive story.

One of my colleagues during their PhD removed an entire chapter from the thesis after writing it as the supervisor said that it needed more experiments to be a full story. They did not want to spend the next six months gathering the data and simply removed the chapter altogether.

How short can PhD dissertation be?

The shortest PhD dissertations are typically found in mathematics.

George Bernard Danzig was an American mathematical scientist who made contributions to industrial engineering and many other mathematical-related fields. An interesting miscommunication led to 1 of the shortest PhD theses ever.

In 1939 his professor wrote two problems on the blackboard and Danzig thought they were homeless assignments. He stated that they were harder than usual but handed in solutions to the surprise of the professor.

They were, in fact, open mathematical problems in statistics.

His professor said to bind the solution to the two problems together and submit them as his thesis – the total thesis length = 14 pages.

Obviously, most PhD theses and dissertations will be so much longer than that!

My PhD dissertation was 256 pages long. It was full of schematics, diagrams, and tables to demonstrate and communicate my findings.

I would say that most people’s PhD thesis experience will be closer to mine than Prof George Bernard Danzig’s.

Why PhD dissertations are typically so long

PhD dissertations are often over 200 pages long.

One of the primary reasons they are so long is that it is a single document that summarises many years of hard work. Also, summarising the research field to date and making sure that all of your references and citations are included so you avoid plagiarism will bolster the word count of the thesis dramatically.

Here are all of the reasons PhD dissertations tend to be so long.

Many years of work

PhD theses or dissertations contain many years of research and analysis.

In many of my YouTube videos I recommend that a PhD student work towards their PhD thesis by doing at least three hours of focused work every work day.

This amount of work quickly adds up.

Of course, not every bit of work makes it into the PhD dissertation but a lot of it does. It can be difficult to work out what to include or leave out of your thesis.

As a PhD student, I perfected the art of turning one experiment into many different types of grafts and schematics to fully explore the limits of my data. The graphs can take up a lot of space in your PhD thesis and, therefore, bolster the page count significantly.

In depth literature review

One of the most substantial parts of a PhD dissertation is the literature review.

The literature review can take up a huge portion of the early part of your PhD dissertation depending on the amount of data and publications in your field.

Writing an in-depth literature review requires just as much meticulous data analysis and searching as the central part of your dissertation.

Figures and schematics

Some fields end up producing a lot of figures and schematics.

My thesis had many full-page figures of atomic force microscopy experiments with much more explanation on subsequent pages.

As they say, a picture paints a thousand words and a dissertation can really benefit from having many schematics to highlight the important aspects of your findings.

References and citations

The recommended PhD dissertation word count from an institution or university does not include citations, references, or other thesis parts such as summary of abbreviations, table of figures, et cetera.

However, these components of your dissertation can take up many pages and add to the overall thickness of your PhD dissertation.

University formatting rules

University formatting rules will also dictate how you many pages your words take up.

I often get roasted on my YouTube channel for having doublespaced lines and wide margins. Unfortunately, this layout was dictated by my university before printing.

PhD dissertations often end up going into long-term storage and therefore, need to adhere to archival and standardised formatting rules.

Deep in the depths of the University of Newcastle, there is a copy of my thesis on a shelf. The formatting and binding rules mean that my thesis looks like everyone else’s.

Universities will often have their own requirements for PhD dissertation cover colour, quality, and type of paper. Even the quality of the paper can change the thickness of the PhD dissertation significantly.

PhD by publication

It is becoming increasingly common to submit a number of peer-reviewed papers bound together with supplementary information in between instead of a PhD dissertation.

The benefits of this to the researcher and university are:

• More early career peer-reviewed journals for career advancement
• an easier review process – they have already been peer-reviewed
• an early focus on publishing means better research outcomes for the researcher, supervisor, and Department.
• No mad rush at the end to finish a thesis
• continually writing peer-reviewed papers throughout your PhD helps with timely analysis and communication of results

Even though this option has been available to PhD students for a number of years, I have only known a handful of students actually submit their PhD via publication.

Nonetheless, having this option will suit some research fields better than others and lead to a more productive PhD.

Wrapping up

This article has been through everything you need to know about the length of a PhD dissertation and the common lengths of PhD dissertations for various fields.

Ultimately, there is no predefined length of a PhD .

A PhD thesis is as long as it needs to be to convince your examiners that you have contributed significantly enough to an academic field to be awarded the title of Dr of philosophy.

Mathematical and analytical theses tend to be shorter and can be as short as 50 pages (with one of the shortest being only 14 pages long). At the other end of the spectrum, PhD students in anthropology and history tend to produce the longest dissertations.

Dr Andrew Stapleton has a Masters and PhD in Chemistry from the UK and Australia. He has many years of research experience and has worked as a Postdoctoral Fellow and Associate at a number of Universities. Although having secured funding for his own research, he left academia to help others with his YouTube channel all about the inner workings of academia and how to make it work for you.

It’s not just a document; it’s a testament to years of intellectual toil, research finesse, and a contribution to the vast expanse of human understanding. But as scholars immerse themselves in the sea of research, a question inevitably surfaces: How long should a Ph.D. dissertation be?

Significance Unveiled

A Ph.D. dissertation is more than a lengthy document; it’s a scholarly masterpiece that not only encapsulates an individual’s intellectual prowess but adds a unique brushstroke to the grand canvas of academia. It’s a beacon of knowledge, guiding future researchers and shaping the trajectory of scholarly discourse. Understanding its significance is the first step toward unlocking the secrets of its length.

Navigating Length: A Delicate Balancing Act

Determining the appropriate length for a Ph.D. dissertation is no mere formality. It’s a delicate dance between providing comprehensive insights and maintaining reader engagement. Striking this balance is crucial, as the length not only influences how the research is perceived but also reflects the researcher’s ability to weave a compelling narrative without unnecessary verbosity.

Factors in the Equation

The length of a dissertation is a dynamic variable influenced by a multitude of factors. From the complexity of the research question to the intricacies of data collection, each element plays a role. It’s a symphony where the depth of the literature review, the intricacy of the methodology, and the nature of the chosen discipline all contribute to the final crescendo of the dissertation length.

Purpose of a PhD Dissertation

At the heart of the Ph.D. journey lies the dissertation, a formidable endeavour that goes beyond being a mere academic requirement. It serves as the cornerstone of a scholar’s intellectual legacy, encapsulating years of research, critical thinking, and a commitment to advancing knowledge in a specific field. The purpose of a Ph.D. dissertation extends far beyond a graduation requirement; it is a scholarly rite of passage that marks one’s entry into the ranks of contributing intellectuals.

B. The Dissertation’s Role in Academic Knowledge

The dissertation, in essence, is a torchbearer of academic knowledge. It doesn’t merely regurgitate existing information but actively contributes to the ongoing conversation within a field. Picture it as a puzzle piece that, when seamlessly integrated, enriches the larger mosaic of human understanding. Its role is not just to summarize what is known but to illuminate uncharted territories, challenging established paradigms and paving the way for new insights.

Example: In the field of environmental science, a Ph.D. dissertation might delve into the impact of climate change on a specific ecosystem, offering novel findings that reshape our understanding of ecological resilience. It becomes a pivotal contribution that informs future research and policy decisions.

Thorough research is the bedrock upon which a meaningful dissertation stands. It involves meticulously exploring existing literature, methodologies, and gaps in knowledge. This isn’t a cursory glance but a deep dive into the scholarly ocean, where each wave of information contributes to the construction of a comprehensive understanding.

Original contributions are the soul of a Ph.D. dissertation. It’s not just about rehashing what’s already known but about introducing something new and transformative. This could be a novel research methodology, a groundbreaking theory, or empirical findings that challenge existing theories.

Example: In the realm of psychology, a Ph.D. dissertation might involve the development of a new therapeutic approach for a specific mental health condition, backed by both a comprehensive review of existing literature and empirical evidence from original studies. This not only adds to the academic discourse but also has tangible implications for clinical practice.

University Guidelines PhD Dissertation Length: Navigating the Academic Framework

In academia, each university sets the stage with its own set of guidelines governing the composition and expectations of a Ph.D. dissertation. These guidelines serve as the rulebook, providing a roadmap for aspiring scholars to traverse the challenging terrain of research and writing. Understanding these guidelines is akin to deciphering the code that unlocks the door to doctoral success.

Dive into the particulars, and you’ll find that universities often outline specific requirements and expectations regarding the length of a dissertation. These may range from prescribed word counts for each section to broader expectations for the overall document. Some institutions might emphasize brevity, while others encourage a more expansive exploration. Unravelling these expectations is not just a bureaucratic formality; it’s a strategic move that ensures your work aligns with the academic standards set by your institution.

Example: Imagine a university that places a strong emphasis on concise and focused dissertations. Here, the guidelines may state a maximum word count for each chapter, encouraging a streamlined and impactful presentation of research findings. Adhering to these specifics ensures that your dissertation not only meets the academic standards but also resonates with the evaluators who appreciate clarity and precision.

While the allure of academic freedom may tempt scholars to chart their own course, adherence to institutional guidelines is paramount. It’s not just a matter of compliance; it’s a strategic decision that aligns your work with the expectations of the academic community. Universities set guidelines with a purpose – to maintain standards, ensure consistency, and facilitate fair evaluation. Ignoring these guidelines can inadvertently hinder the reception of your dissertation, potentially overshadowing the brilliance of your research with concerns about adherence to academic norms.

Disciplinary Variances: Navigating the Length Spectrum

In the vast landscape of academia, one size certainly does not fit all, especially when it comes to the length of Ph.D. dissertations. It’s crucial to acknowledge and appreciate the dynamic nature of disciplinary differences, where each field has its own set of expectations, traditions, and scholarly norms. Understanding this diversity is the key to crafting a dissertation that resonates within the specific academic community to which it belongs.

Let’s take a stroll through different academic landscapes to grasp the breadth of expectations. In the sciences, precision and brevity often reign supreme. A molecular biology dissertation, for instance, may prioritize concise methodology and results chapters, with an emphasis on data interpretation. Contrast this with a dissertation in the humanities, where the richness of language and the depth of literary analysis might lead to a more extensive exploration of concepts.

Example: In engineering, a Ph.D. dissertation might lean towards a succinct presentation of methodologies, experimental results, and their implications for the field. Meanwhile, in the realm of philosophy, a dissertation could be characterized by a more expansive engagement with existing literature and a thorough philosophical exploration of the research question.

The beauty of academia lies in its diversity, but this very diversity requires scholars to be attuned to the norms of their specific discipline. What might be considered a concise and impactful dissertation in one field could be seen as lacking depth in another. Recognizing these norms is not just a matter of fitting in; it’s a strategic decision that ensures your work aligns with the expectations of your academic peers.

Understanding disciplinary norms is like speaking the language of your scholarly community. It’s about knowing when to be succinct and when to elaborate, when to prioritize methodology and when to delve deep into theoretical frameworks.

Factors Influencing PhD Dissertation Length

1. Impact of Research Question Complexity

The complexity of your research question is like the compass guiding the depth and breadth of your dissertation. Intricate inquiries often demand more comprehensive exploration, delving into multiple facets and dimensions. For instance, a research question investigating the genetic determinants of a rare disease may necessitate an extensive review of existing literature, detailed methodologies, and intricate analyses to uncover meaningful insights.

2. Examples of Research Topics

Consider the following examples to illustrate the point:

• Less Complex: An analysis of consumer behavior in response to a specific marketing strategy might require a detailed but more straightforward exploration.
• More Complex: On the other hand, a study examining the intersection of artificial intelligence and ethical considerations in healthcare may demand a multifaceted investigation into both technological and ethical dimensions, significantly impacting the length of the dissertation.

1. Influence of Data Nature and Quantity

The nature and amount of data collected cast a profound shadow on dissertation length. A project relying on extensive datasets, intricate statistical analyses, or comprehensive case studies inherently demands a more extended exploration. In contrast, qualitative research might be more concise but equally impactful in unraveling complex phenomena.

2. Role of Statistical Analysis, Case Studies, or Qualitative Research

Consider the following scenarios:

• Statistical Analysis: A dissertation delving into the economic impact of climate change policies might involve sophisticated statistical models and require an in-depth presentation of results and their implications.
• Qualitative Research: Conversely, a dissertation employing qualitative interviews to explore the lived experiences of individuals facing a specific social challenge may present findings in a more narrative form.

1. Significance of a Comprehensive Literature Review

A robust literature review acts as the scaffolding for your dissertation, providing the theoretical foundation and context for your research. The broader and more complex the field, the more extensive the literature review. For instance, exploring a niche area within a rapidly evolving field, like emerging technologies, may demand a more thorough literature review to capture the latest developments and debates.

2. Contribution to Overall Length

Consider this:

• A dissertation in environmental science, investigating the impact of urbanization on biodiversity, might necessitate a detailed exploration of existing literature on ecology, urban planning, and biodiversity conservation.

1. Impact of Detailed Research Methodology

The methodology section is the blueprint of your research, and its level of detail significantly influences the length of your dissertation. A dissertation with a meticulous methodology section is like a well-constructed building, providing a clear roadmap for readers to understand the research process.

2. Need for Clarity and Precision in Research Design

For example:

• A dissertation in public health aiming to assess the effectiveness of a health intervention might require a detailed explanation of the study design, participant recruitment strategies, and data collection methods to ensure the study’s validity and reliability.

Balancing Depth and Brevity: Crafting a Dissertation Masterpiece

In the symphony of scholarly writing, achieving harmony between depth and brevity is a skill that distinguishes a stellar dissertation. While delving deep into the nuances of your research is essential, presenting it with conciseness ensures that your audience remains engaged. The challenge lies in striking the right balance, where the richness of content is not sacrificed on the altar of brevity.

• Clear Research Objectives: Begin with well-defined research objectives that serve as the North Star for your dissertation. This clarity guides your writing, preventing unnecessary tangents and ensuring each section contributes directly to your overarching goals. Example: In a dissertation exploring the impact of mindfulness-based interventions on stress reduction, clear objectives would center around understanding the effectiveness of specific mindfulness techniques and their implications for stress management.
• Thematic Structure: Organize your dissertation thematically, ensuring each chapter has a clear purpose and contributes to building a cohesive narrative. This not only aids readability but also enhances the overall impact of your research. Example: In a literature review, grouping studies thematically—such as by intervention type or outcome measures—provides a structured and focused presentation of existing research, avoiding a scattered and disjointed narrative.
• Rigorous Editing: Approach your writing with a discerning eye during the editing process. Trim unnecessary words, sentences, or sections that do not directly contribute to the core message of your dissertation. Be ruthless in maintaining relevance. Example: In the methodology section, focus on explaining key decisions and processes, omitting redundant details that do not influence the study’s validity or replicability.
• Depth of Analysis: Instead of inundating your dissertation with an abundance of superficial analyses, delve deep into a few key points. Thoroughly explore the significance and implications of your findings, providing a nuanced understanding of your research. Example: In a discussion section, rather than covering multiple tangential points, focus on the most critical aspects of your results, analyzing their theoretical and practical implications in detail.
• Precision in Language: Choose words judiciously to convey your ideas with precision. Aim for clarity without unnecessary embellishments, ensuring that each sentence adds value to your argument. Example: In the introduction, use concise language to clearly articulate the research gap, the significance of the study, and the specific research questions without unnecessary elaboration.
• Selectivity in Citations: While a comprehensive literature review is vital, selectively cite studies that directly contribute to your research context. Avoid an exhaustive list that overwhelms readers with unnecessary details. Example: In a literature review on educational interventions for students with learning disabilities, selectively cite studies that showcase diverse approaches and methodologies, providing a nuanced understanding of the existing landscape.

As we navigate the delicate equilibrium between depth and brevity, remember that a well-crafted dissertation is not measured by its length but by the impact of its scholarly contributions. Join us as we explore the art of balancing substance with succinctness, ensuring your dissertation stands as a masterpiece in the annals of academic inquiry.

Tips for Managing PhD Dissertation Length: Navigating the Dissertation Writing Process

• Setting Realistic Milestones: Break down the dissertation-writing process into manageable milestones. Establish realistic timelines for each section, considering the complexity and time required for research, writing, and revisions. Example: Allocate a specific time frame for conducting literature reviews, data analysis, and drafting each chapter. This ensures steady progress and prevents last-minute rushes.
• Regular Progress Checks: Monitor your progress regularly and adjust your schedule as needed. If a particular section is taking longer than anticipated, evaluate the reasons and recalibrate your timeline accordingly. Example: If data analysis is proving more time-consuming than expected, revisit your research plan and, if necessary, adjust your writing schedule for subsequent chapters.
• Balancing Research and Writing: Strive for a balance between conducting research and writing. While research is crucial, allocate dedicated time for translating findings into written content to avoid a backlog of information. Example: If you’re conducting experiments, allocate specific writing sessions to summarize and interpret the results, ensuring a continuous flow of progress.

• Clarity in Expression: Aim for clarity in your writing. Express complex ideas in straightforward language, avoiding unnecessary jargon or convoluted sentences that can inflate the word count without adding substance. Example: Instead of using complex terminology in a theoretical framework, opt for clear and precise language that conveys the theoretical concepts without unnecessary embellishments.
• Economical Word Choices: Choose words judiciously. Opt for strong, impactful words that convey your message succinctly. Trim redundant phrases and eliminate words that don’t contribute directly to your argument. Example: Instead of saying “due to the fact that,” use the more concise “because” to convey the same meaning with fewer words.
• Strategic Use of Figures and Tables: Incorporate visuals strategically to convey information efficiently. Figures and tables can often replace lengthy textual explanations, providing a visual representation of data or concepts. Example: Instead of describing a complex set of results in paragraphs, present key findings in a well-designed table, allowing readers to grasp the information at a glance.
• Early and Regular Feedback: Share drafts of your work with advisors and peers early in the writing process. Their feedback can identify potential issues and guide revisions, preventing the need for extensive rewrites later. Example: Submit a draft of your literature review to your advisor before completing the entire chapter. Early feedback can help refine your approach and ensure you’re on the right track.
• Objective External Perspectives: Advisors and peers offer valuable external perspectives. They can identify areas where your explanation may be unclear or where additional details may be necessary. Example: If your research methodology is intricate, seek feedback from a peer who is not intimately familiar with your topic. Their questions and comments can reveal where additional clarification is needed for a broader audience.
• Critical Review for Redundancy: Advisors and peers can help identify redundant sections or unnecessary details. A fresh set of eyes can pinpoint areas where content can be streamlined without compromising the depth of your argument. Example: If two sections of your dissertation cover similar ground, feedback from others can highlight the need to merge or eliminate redundant content, improving the overall flow.

Embarking on a PhD is “probably the most challenging task that a young scholar attempts to do”, write Mark Stephan Felix and Ian Smith in their practical guide to dissertation and thesis writing. After years of reading and research to answer a specific question or proposition, the candidate will submit about 80,000 words that explain their methods and results and demonstrate their unique contribution to knowledge. Here are the answers to frequently asked questions about writing a doctoral thesis or dissertation.

What’s the difference between a dissertation and a thesis?

Whatever the genre of the doctorate, a PhD must offer an original contribution to knowledge. The terms “dissertation” and “thesis” both refer to the long-form piece of work produced at the end of a research project and are often used interchangeably. Which one is used might depend on the country, discipline or university. In the UK, “thesis” is generally used for the work done for a PhD, while a “dissertation” is written for a master’s degree. The US did the same until the 1960s, says Oxbridge Essays, when the convention switched, and references appeared to a “master’s thesis” and “doctoral dissertation”. To complicate matters further, undergraduate long essays are also sometimes referred to as a thesis or dissertation.

The Oxford English Dictionary defines “thesis” as “a dissertation, especially by a candidate for a degree” and “dissertation” as “a detailed discourse on a subject, especially one submitted in partial fulfilment of the requirements of a degree or diploma”.

The title “doctor of philosophy”, incidentally, comes from the degree’s origins, write Dr Felix, an associate professor at Mahidol University in Thailand, and Dr Smith, retired associate professor of education at the University of Sydney , whose co-authored guide focuses on the social sciences. The PhD was first awarded in the 19th century by the philosophy departments of German universities, which at that time taught science, social science and liberal arts.

How long should a PhD thesis be?

A PhD thesis (or dissertation) is typically 60,000 to 120,000 words ( 100 to 300 pages in length ) organised into chapters, divisions and subdivisions (with roughly 10,000 words per chapter) – from introduction (with clear aims and objectives) to conclusion.

The structure of a dissertation will vary depending on discipline (humanities, social sciences and STEM all have their own conventions), location and institution. Examples and guides to structure proliferate online. The University of Salford , for example, lists: title page, declaration, acknowledgements, abstract, table of contents, lists of figures, tables and abbreviations (where needed), chapters, appendices and references.

A scientific-style thesis will likely need: introduction, literature review, materials and methods, results, discussion, bibliography and references.

As well as checking the overall criteria and expectations of your institution for your research, consult your school handbook for the required length and format (font, layout conventions and so on) for your dissertation.

A PhD takes three to four years to complete; this might extend to six to eight years for a part-time doctorate.

What are the steps for completing a PhD?

Before you get started in earnest , you’ll likely have found a potential supervisor, who will guide your PhD journey, and done a research proposal (which outlines what you plan to research and how) as part of your application, as well as a literature review of existing scholarship in the field, which may form part of your final submission.

In the UK, PhD candidates undertake original research and write the results in a thesis or dissertation, says author and vlogger Simon Clark , who posted videos to YouTube throughout his own PhD journey . Then they submit the thesis in hard copy and attend the viva voce (which is Latin for “living voice” and is also called an oral defence or doctoral defence) to convince the examiners that their work is original, understood and all their own. Afterwards, if necessary, they make changes and resubmit. If the changes are approved, the degree is awarded.

The steps are similar in Australia , although candidates are mostly assessed on their thesis only; some universities may include taught courses, and some use a viva voce. A PhD in Australia usually takes three years full time.

In the US, the PhD process begins with taught classes (similar to a taught master’s) and a comprehensive exam (called a “field exam” or “dissertation qualifying exam”) before the candidate embarks on their original research. The whole journey takes four to six years.

A PhD candidate will need three skills and attitudes to get through their doctoral studies, says Tara Brabazon , professor of cultural studies at Flinders University in Australia who has written extensively about the PhD journey :

• master the academic foundational skills (research, writing, ability to navigate different modalities)
• time-management skills and the ability to focus on reading and writing
• determined motivation to do a PhD.

How do I choose the topic for my PhD dissertation or thesis?

It’s important to find a topic that will sustain your interest for the years it will take to complete a PhD. “Finding a sustainable topic is the most important thing you [as a PhD student] would do,” says Dr Brabazon in a video for Times Higher Education . “Write down on a big piece of paper all the topics, all the ideas, all the questions that really interest you, and start to cross out all the ones that might just be a passing interest.” Also, she says, impose the “Who cares? Who gives a damn?” question to decide if the topic will be useful in a future academic career.

The availability of funding and scholarships is also often an important factor in this decision, says veteran PhD supervisor Richard Godwin, from Harper Adams University .

Define a gap in knowledge – and one that can be questioned, explored, researched and written about in the time available to you, says Gina Wisker, head of the Centre for Learning and Teaching at the University of Brighton. “Set some boundaries,” she advises. “Don’t try to ask everything related to your topic in every way.”

James Hartley, research professor in psychology at Keele University, says it can also be useful to think about topics that spark general interest. If you do pick something that taps into the zeitgeist, your findings are more likely to be noticed.

You also need to find someone else who is interested in it, too. For STEM candidates , this will probably be a case of joining a team of people working in a similar area where, ideally, scholarship funding is available. A centre for doctoral training (CDT) or doctoral training partnership (DTP) will advertise research projects. For those in the liberal arts and social sciences, it will be a matter of identifying a suitable supervisor .

Avoid topics that are too broad (hunger across a whole country, for example) or too narrow (hunger in a single street) to yield useful solutions of academic significance, write Mark Stephan Felix and Ian Smith. And ensure that you’re not repeating previous research or trying to solve a problem that has already been answered. A PhD thesis must be original.

What is a thesis proposal?

After you have read widely to refine your topic and ensure that it and your research methods are original, and discussed your project with a (potential) supervisor, you’re ready to write a thesis proposal , a document of 1,500 to 3,000 words that sets out the proposed direction of your research. In the UK, a research proposal is usually part of the application process for admission to a research degree. As with the final dissertation itself, format varies among disciplines, institutions and countries but will usually contain title page, aims, literature review, methodology, timetable and bibliography. Examples of research proposals are available online.

How to write an abstract for a dissertation or thesis

The abstract presents your thesis to the wider world – and as such may be its most important element , says the NUI Galway writing guide. It outlines the why, how, what and so what of the thesis . Unlike the introduction, which provides background but not research findings, the abstract summarises all sections of the dissertation in a concise, thorough, focused way and demonstrates how well the writer understands their material. Check word-length limits with your university – and stick to them. About 300 to 500 words is a rough guide ­– but it can be up to 1,000 words.

The abstract is also important for selection and indexing of your thesis, according to the University of Melbourne guide , so be sure to include searchable keywords.

It is the first thing to be read but the last element you should write. However, Pat Thomson , professor of education at the University of Nottingham , advises that it is not something to be tackled at the last minute.

How to write a stellar conclusion

As well as chapter conclusions, a thesis often has an overall conclusion to draw together the key points covered and to reflect on the unique contribution to knowledge. It can comment on future implications of the research and open up new ideas emanating from the work. It is shorter and more general than the discussion chapter , says online editing site Scribbr, and reiterates how the work answers the main question posed at the beginning of the thesis. The conclusion chapter also often discusses the limitations of the research (time, scope, word limit, access) in a constructive manner.

It can be useful to keep a collection of ideas as you go – in the online forum DoctoralWriting SIG , academic developer Claire Aitchison, of the University of South Australia , suggests using a “conclusions bank” for themes and inspirations, and using free-writing to keep this final section fresh. (Just when you feel you’ve run out of steam.) Avoid aggrandising or exaggerating the impact of your work. It should remind the reader what has been done, and why it matters.

How to format a bibliography (or where to find a reliable model)

Most universities use a preferred style of references , writes THE associate editor Ingrid Curl. Make sure you know what this is and follow it. “One of the most common errors in academic writing is to cite papers in the text that do not then appear in the bibliography. All references in your thesis need to be cross-checked with the bibliography before submission. Using a database during your research can save a great deal of time in the writing-up process.”

A bibliography contains not only works cited explicitly but also those that have informed or contributed to the research – and as such illustrates its scope; works are not limited to written publications but include sources such as film or visual art.

Examiners can start marking from the back of the script, writes Dr Brabazon. “Just as cooks are judged by their ingredients and implements, we judge doctoral students by the calibre of their sources,” she advises. She also says that candidates should be prepared to speak in an oral examination of the PhD about any texts included in their bibliography, especially if there is a disconnect between the thesis and the texts listed.

Can I use informal language in my PhD?

Don’t write like a stereotypical academic , say Kevin Haggerty, professor of sociology at the University of Alberta , and Aaron Doyle, associate professor in sociology at Carleton University , in their tongue-in-cheek guide to the PhD journey. “If you cannot write clearly and persuasively, everything about PhD study becomes harder.” Avoid jargon, exotic words, passive voice and long, convoluted sentences – and work on it consistently. “Writing is like playing guitar; it can improve only through consistent, concerted effort.”

Be deliberate and take care with your writing . “Write your first draft, leave it and then come back to it with a critical eye. Look objectively at the writing and read it closely for style and sense,” advises THE ’s Ms Curl. “Look out for common errors such as dangling modifiers, subject-verb disagreement and inconsistency. If you are too involved with the text to be able to take a step back and do this, then ask a friend or colleague to read it with a critical eye. Remember Hemingway’s advice: ‘Prose is architecture, not interior decoration.’ Clarity is key.”

How often should a PhD candidate meet with their supervisor?

Since the PhD supervisor provides a range of support and advice – including on research techniques, planning and submission – regular formal supervisions are essential, as is establishing a line of contact such as email if the candidate needs help or advice outside arranged times. The frequency varies according to university, discipline and individual scholars.

Once a week is ideal, says Dr Brabazon. She also advocates a two-hour initial meeting to establish the foundations of the candidate-supervisor relationship .

The University of Edinburgh guide to writing a thesis suggests that creating a timetable of supervisor meetings right at the beginning of the research process will allow candidates to ensure that their work stays on track throughout. The meetings are also the place to get regular feedback on draft chapters.

“A clear structure and a solid framework are vital for research,” writes Dr Godwin on THE Campus . Use your supervisor to establish this and provide a realistic view of what can be achieved. “It is vital to help students identify the true scientific merit, the practical significance of their work and its value to society.”

How to proofread your dissertation (what to look for)

Proofreading is the final step before printing and submission. Give yourself time to ensure that your work is the best it can be . Don’t leave proofreading to the last minute; ideally, break it up into a few close-reading sessions. Find a quiet place without distractions. A checklist can help ensure that all aspects are covered.

Proofing is often helped by a change of format – so it can be easier to read a printout rather than working off the screen – or by reading sections out of order. Fresh eyes are better at spotting typographical errors and inconsistencies, so leave time between writing and proofreading. Check with your university’s policies before asking another person to proofread your thesis for you.

As well as close details such as spelling and grammar, check that all sections are complete, all required elements are included , and nothing is repeated or redundant. Don’t forget to check headings and subheadings. Does the text flow from one section to another? Is the structure clear? Is the work a coherent whole with a clear line throughout?

Ensure consistency in, for example, UK v US spellings, capitalisation, format, numbers (digits or words, commas, units of measurement), contractions, italics and hyphenation. Spellchecks and online plagiarism checkers are also your friend.

How do you manage your time to complete a PhD dissertation?

Treat your PhD like a full-time job, that is, with an eight-hour working day. Within that, you’ll need to plan your time in a way that gives a sense of progress . Setbacks and periods where it feels as if you are treading water are all but inevitable, so keeping track of small wins is important, writes A Happy PhD blogger Luis P. Prieto.

Be specific with your goals – use the SMART acronym (specific, measurable, attainable, relevant and timely).

And it’s never too soon to start writing – even if early drafts are overwritten and discarded.

“ Write little and write often . Many of us make the mistake of taking to writing as one would take to a sprint, in other words, with relatively short bursts of intense activity. Whilst this can prove productive, generally speaking it is not sustainable…In addition to sustaining your activity, writing little bits on a frequent basis ensures that you progress with your thinking. The comfort of remaining in abstract thought is common; writing forces us to concretise our thinking,” says Christian Gilliam, AHSS researcher developer at the University of Cambridge ’s Centre for Teaching and Learning.

Make time to write. “If you are more alert early in the day, find times that suit you in the morning; if you are a ‘night person’, block out some writing sessions in the evenings,” advises NUI Galway’s Dermot Burns, a lecturer in English and creative arts. Set targets, keep daily notes of experiment details that you will need in your thesis, don’t confuse writing with editing or revising – and always back up your work.

What work-life balance tips should I follow to complete my dissertation?

During your PhD programme, you may have opportunities to take part in professional development activities, such as teaching, attending academic conferences and publishing your work. Your research may include residencies, field trips or archive visits. This will require time-management skills as well as prioritising where you devote your energy and factoring in rest and relaxation. Organise your routine to suit your needs , and plan for steady and regular progress.

How to deal with setbacks while writing a thesis or dissertation

Have a contingency plan for delays or roadblocks such as unexpected results.

Accept that writing is messy, first drafts are imperfect, and writer’s block is inevitable, says Dr Burns. His tips for breaking it include relaxation to free your mind from clutter, writing a plan and drawing a mind map of key points for clarity. He also advises feedback, reflection and revision: “Progressing from a rough version of your thoughts to a superior and workable text takes time, effort, different perspectives and some expertise.”

“Academia can be a relentlessly brutal merry-go-round of rejection, rebuttal and failure,” writes Lorraine Hope , professor of applied cognitive psychology at the University of Portsmouth, on THE Campus. Resilience is important. Ensure that you and your supervisor have a relationship that supports open, frank, judgement-free communication.

• How it works

What Is The Average Dissertation Length?

Published by Alvin Nicolas at March 4th, 2024 , Revised On March 5, 2024

There is no one-size-fits-all answer when it comes to answering the question, “How long should my dissertation be?”. However, the standard is as follows. 

Shorter Dissertations

Some fields or programs may have shorter dissertation requirements, particularly in disciplines where the research tends to be more focused or where a shorter document suffices to convey the research findings. In such cases, dissertations might range from 50 to 100 pages or even shorter.

Average-Length Dissertations

For many doctoral programs, particularly in the humanities, social sciences, and some STEM fields, the average dissertation length falls between 150 and 300 pages . This length allows for a thorough exploration of the research topic , a review of literature , methodology , data analysis , and a discussion of findings .

Longer Dissertations

In certain scientific or technical fields and interdisciplinary studies, dissertations can be longer, ranging from 300 to 500 pages or more. These longer dissertations often involve extensive data collection, complex analyses, multiple experiments or case studies, and detailed discussion of results and implications.

Factors Affecting Dissertation Length

There are a number of factors that contribute to the length, including

Field of Study

Your dissertation depends on your discipline. Humanities and social sciences usually have a lower average word count compared to sciences and engineering because the latter requires extensive data analysis and experimentation. 

University Requirements

Most universities have certain specific guidelines influenced by department and faculty expectations. It is important to go through them before you start writing. 

Research Methodology

The complexity of the research design and methodology can impact the length. Dissertations having comprehensive data collection might need additional space for detailed justification. 

Literature Review

Depending on how novel your research topic is, the length of your literature review varies. If there is a lot of research done on your variables, your dissertation will be longer. 

Can a dissertation exceed recommended length?

Yes, but ensure all content is relevant and contributes meaningfully to the research.

How can I manage dissertation length effectively?

Plan meticulously, prioritize content, and seek feedback to ensure conciseness without sacrificing depth.

• How It Works

How Long Should Your PhD Dissertation Be?

A PhD dissertation is the essential part of a research-based degree since it reflects the student’s knowledge and experience in the field. However, there are some subtle areas that can be frustrating and misleading for many students PhD students. One of the key aspects of the dissertation is its length. Typically, the standard PhD dissertation is 60,000-80,000 words in length, but there is no one size fits all solution. What is definitely known is that a PhD thesis is significantly larger than an MA dissertation. However, it is important to note that PhD thesis writing is about critical analysis, novelty in research and quality of writing. Hence, the PhD writing should firstly focus on the quality of research rather than quantity. This article aims to find out the recommended length of a dissertation at a PhD level.

1. Different approaches to writing PhD dissertations

Many students are looking for PhD help and high-quality writing services and size of the thesis is one of the most difficult questions to answer. When talking about PhD thesis writing, it is important to emphasise the depth of research and comprehensive analysis of all theories and points. This means that size of a dissertation depends on the specific project requirements. For some dissertations that focus heavily on theoretical considerations, the size is likely to be higher. In this case, there is a lot more past literature to be reviewed and more theories to consider. More empirical works rely on a slightly different approach to thesis writing. In this case, the thesis is expected to be a little bit shorter but more empirical. That is, the key value of the thesis comes from empirical findings rather than theoretical review. Therefore, there are different approaches to writing dissertations thereby affecting length of the thesis. However, the minimum length is about 60,000 words, but the key focus is on the depth of research.

2. Subject area and thesis writing

In addition, the length of a dissertation depends on the subject area. For more research-intensive subject areas, there is more information to include in the dissertation. This naturally leads to higher length of the thesis. For areas with much previous literature attention the word count is likely to be larger because of more massive literature review and more opportunities for research. Some new projects with the lack of the academic focus in the past can be shorter. Thesis writing for a social sciences course implies probably larger project size compared to the thesis for science or medicine. Nevertheless, there is no strict answer to this question on the size of a PhD dissertation. There are different factors that come into play and the subject area is one of them.

3. University rules

Another important factor to consider is the university and its PhD dissertation rules and word limits. PhD thesis writing is similar across universities but there are some notable differences. Some universities allow for more strict word limits such as 75,000-80,000 words. Others set higher word limits of 100,000 words or more. Generally, university or course requirements influence size of a PhD thesis. This means that there is no one answer on the size of the thesis paper. Each university has its own standards for PhD thesis writing, so there are significant variations across universities.

The question on how long the PhD dissertation should be is not new. Moreover, each year there are thousands of students who ask exactly the same question. The simple answer can be – “long enough to properly answer the question”. This means that there is no one size that fits all theses. The length of the paper depends on the subject area and university. In addition, depth of research also affects the thesis writing and length of a PhD thesis. Most of theses range from 70,000 to 100,000 words in size. However, each student should consult with his/her faculty on the project size.

How Long is a Dissertation for a PhD?

How long is a dissertation? This is one of the most common questions asked by current or aspiring doctoral students.

A dissertation is an extensive research project that contributes fresh knowledge to the author’s field. Many doctoral programs require students to write, defend, and revise a dissertation to earn their degrees.

Editorial Listing ShortCode:

This article explores the average length of a dissertation and various factors that affect the scope of these papers.

How Long Is a Dissertation?

For most graduate students, the dissertation is the longest and most time-consuming paper they write throughout their education. This project aims to address a research question in the student’s field and build on existing bodies of scholarship.

Additionally, the dissertation showcases the student’s mastery of research methodologies. Because a dissertation must accomplish several goals, they tend to be ambitious and lengthy.

Most dissertations are 100 to 250 pages long. But many factors impact the length of a dissertation, including:

• Academic field . Each discipline has different norms regarding dissertation content and length. For instance, literature dissertations often include extended close readings of texts, while science dissertations focus more on data analysis and research design. As a result, humanities dissertations are typically longer.
• Institutional requirements . Most colleges and universities specify a minimum number of pages for the dissertation. You can ask your academic advisor or the graduate studies office about specific dissertation guidelines.
• Topic complexity . Broad or complex research questions may require more data and analysis to answer, resulting in a longer dissertation.
• Individual writing style . Some doctoral students enjoy writing elaborate and detailed sentences, while others prefer to get straight to the point.
• Research methodologies . The approaches and methods used in the research can dramatically affect the length of the dissertation. For example, some dissertations include case studies, which may require lengthy explanations and analyses. Others use quantitative research methods and may include a number of charts and figures.
• Committee feedback . Graduate students typically write their dissertations under the supervision of a faculty committee. These professors may recommend adding or cutting material during revision, impacting the dissertation’s final length.
• Future goals . Some doctoral students plan to revise their dissertation and publish it as an academic monograph after graduation. Writing a longer dissertation gives them more material to adapt for their book.

Reading dissertations from your department and field can give you a better sense of the typical length.

How Long Are Dissertations by Discipline?

The answer to “how long is a doctoral dissertation?” varies by field. In some disciplines, it’s common for graduate students to spend several years writing extensive manuscripts. Other fields produce shorter dissertations of approximately 100 pages.

Here are a few examples of dissertation norms for different disciplines:

• Arts : Students studying art and creative writing may produce a creative dissertation. These projects typically consist of a theoretical introduction and a creative project, such as a poetry collection or a series of paintings. Creative dissertations may have fewer than 100 written pages, but the artistic elements can still be time-consuming.
• Chemistry : These dissertations typically range from 100 to 150 pages. They typically describe experimental methodologies and draw conclusions from the author’s findings.
• Computer science : Dissertations in this field are generally 50 to 150 pages long and often include quantitative data and algorithms.
• English : PhD students in this field frequently write lengthy literature reviews and provide in-depth analyses of novels and other texts. English dissertations may range from 200 to 350 pages.

Faculty in your discipline can help you understand dissertation expectations.

Average Dissertation Length Per Chapter

Dissertations typically have similar components and structures across disciplines. Here are six common chapters and their average lengths:

• Introduction : The first chapter introduces the primary research topic and explains its relevance to the field. The introduction also provides a brief overview of the investigation method. Most introductions are 10 to 25 pages long.
• Literature review : This chapter situates the project within the broader discipline. The author analyzes existing sources already written on their research topic and identifies biases or gaps that their own project remedies. Humanities dissertations tend to have 20 to 30 page literature reviews, while STEM dissertations devote 10 to 20 pages to this component.
• Methodology : The third chapter typically focuses on the methods and techniques used to gather data. Ideally, this description should contain all the details that another researcher would need to duplicate the experiment and verify the results. The methodology chapter ranges from 15 to 25 pages, depending on the complexity of the research.
• Findings : This section analyzes the collected data and discusses the results of the research project. It often includes charts, diagrams, and other data visualizations illustrating the findings. This chapter could be 20 to 50 pages, depending on the number of images and the amount of text needed to thoroughly examine the results.
• Discussion : This chapter explains the significance of the results. The author may also compare their findings to previously published scholarship. The discussion is typically 15 to 25 pages.
• Conclusion : The author summarizes their findings, acknowledges the limitations of their research, and suggests avenues for future studies. Most conclusions consist of 15 to 20 pages.

Some dissertations deviate from this format. For instance, English dissertations may devote several chapters to critical analyses of different genres or authors.

What Is a Dissertation?

A dissertation is a lengthy written document that a doctoral student produces based on their original research. This project demonstrates the student’s expertise in their area of specialty and contributes to existing knowledge in the field.

Dissertations typically fall into one of two categories. Empirical dissertations require students to collect and analyze data. For instance, a psychology student may interview people about their mental health, while a marketing student could interpret sales data.

Theoretical dissertations focus on analyzing existing scholarship and secondary sources. For example, a literature student might research psychoanalysis and apply this approach to superhero comics.

How Many Pages Is a Dissertation?

The length of a dissertation varies by discipline, institution, and research project. Some dissertations can be as short as 50 pages, while others may total 400 pages. But the average dissertation ranges from 100 pages to 250 pages.

Dissertations in the humanities and social sciences are typically the most extensive. These projects often include detailed analyses, case studies, and literature reviews. By contrast, dissertations in STEM fields like economics and mathematics are often 150 pages or less.

Students in these disciplines frequently use mathematical formulas and data visualizations to prove their findings, resulting in less text.

Why Are Dissertations So Long?

Dissertations are typically the most extended assignments that students complete in graduate school. Several factors contribute to their length, including:

• Depth of research . Doctoral students can spend several years researching their topic and analyzing data. This extensive work often takes hundreds of pages to summarize and explain.
• Literature review . Most fields have extensive bodies of scholarship, so students spend many pages analyzing sources and contextualizing their projects.
• Bibliography . Dissertations often cite dozens or even hundreds of sources, resulting in lengthy bibliographies.

Also, colleges often require dissertations to include additional materials like abstracts and tables of content.

What’s the Difference Between a Dissertation vs. Thesis?

Depending on the type of graduate program you enroll in, you may be required to write a dissertation or thesis. Here are the main differences between a thesis vs. dissertation .

If you want to develop your own concepts or theories, a dissertation can help you accomplish this goal.

What’s the Difference Between a Capstone vs. Dissertation?

There are doctorate programs with no dissertation. Like some online doctoral programs in education without dissertation requirements, they have a capstone project instead. Here’s a comparison of a dissertation vs. capstone .

Your career goals can help determine if a capstone or dissertation is right for you.

How Long Is a Dissertation for a PhD Degree?

People often wonder, “How long is a PhD dissertation?” These projects are typically 100 to 250 pages long, though dissertations on complex topics may total more than 400 pages.

Writing a dissertation allows you to develop advanced expertise on your chosen research topic. Many students also publish portions of their dissertations as peer-reviewed articles and share their findings at conferences. These activities enhance your CV and may make you more competitive for academic jobs.

Frequently asked questions

How long is a dissertation.

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

Frequently asked questions: Dissertation

A dissertation prospectus or proposal describes what or who you plan to research for your dissertation. It delves into why, when, where, and how you will do your research, as well as helps you choose a type of research to pursue. You should also determine whether you plan to pursue qualitative or quantitative methods and what your research design will look like.

It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives , ready to be approved by your supervisor or committee.

Note that some departments require a defense component, where you present your prospectus to your committee orally.

A thesis is typically written by students finishing up a bachelor’s or Master’s degree. Some educational institutions, particularly in the liberal arts, have mandatory theses, but they are often not mandatory to graduate from bachelor’s degrees. It is more common for a thesis to be a graduation requirement from a Master’s degree.

Even if not mandatory, you may want to consider writing a thesis if you:

• Plan to attend graduate school soon
• Have a particular topic you’d like to study more in-depth
• Are considering a career in research
• Would like a capstone experience to tie up your academic experience

The conclusion of your thesis or dissertation should include the following:

• A restatement of your research question
• A summary of your key arguments and/or results
• A short discussion of the implications of your research

The conclusion of your thesis or dissertation shouldn’t take up more than 5–7% of your overall word count.

For a stronger dissertation conclusion , avoid including:

• Important evidence or analysis that wasn’t mentioned in the discussion section and results section
• Generic concluding phrases (e.g. “In conclusion …”)
• Weak statements that undermine your argument (e.g., “There are good points on both sides of this issue.”)

Your conclusion should leave the reader with a strong, decisive impression of your work.

While it may be tempting to present new arguments or evidence in your thesis or disseration conclusion , especially if you have a particularly striking argument you’d like to finish your analysis with, you shouldn’t. Theses and dissertations follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the discussion section and results section .) The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

A theoretical framework can sometimes be integrated into a  literature review chapter , but it can also be included as its own chapter or section in your dissertation . As a rule of thumb, if your research involves dealing with a lot of complex theories, it’s a good idea to include a separate theoretical framework chapter.

A literature review and a theoretical framework are not the same thing and cannot be used interchangeably. While a theoretical framework describes the theoretical underpinnings of your work, a literature review critically evaluates existing research relating to your topic. You’ll likely need both in your dissertation .

While a theoretical framework describes the theoretical underpinnings of your work based on existing research, a conceptual framework allows you to draw your own conclusions, mapping out the variables you may use in your study and the interplay between them.

A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organize your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.

Generally, an outline contains information on the different sections included in your thesis or dissertation , such as:

• Your anticipated title
• Your abstract
• Your chapters (sometimes subdivided into further topics like literature review , research methods , avenues for future research, etc.)

When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation .

In most styles, the title page is used purely to provide information and doesn’t include any images. Ask your supervisor if you are allowed to include an image on the title page before doing so. If you do decide to include one, make sure to check whether you need permission from the creator of the image.

Include a note directly beneath the image acknowledging where it comes from, beginning with the word “ Note .” (italicized and followed by a period). Include a citation and copyright attribution . Don’t title, number, or label the image as a figure , since it doesn’t appear in your main text.

Definitional terms often fall into the category of common knowledge , meaning that they don’t necessarily have to be cited. This guidance can apply to your thesis or dissertation glossary as well.

However, if you’d prefer to cite your sources , you can follow guidance for citing dictionary entries in MLA or APA style for your glossary.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, an index is a list of the contents of your work organized by page number.

The title page of your thesis or dissertation goes first, before all other content or lists that you may choose to include.

The title page of your thesis or dissertation should include your name, department, institution, degree program, and submission date.

Glossaries are not mandatory, but if you use a lot of technical or field-specific terms, it may improve readability to add one to your thesis or dissertation. Your educational institution may also require them, so be sure to check their specific guidelines.

A glossary or “glossary of terms” is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. Your glossary only needs to include terms that your reader may not be familiar with, and is intended to enhance their understanding of your work.

A glossary is a collection of words pertaining to a specific topic. In your thesis or dissertation, it’s a list of all terms you used that may not immediately be obvious to your reader. In contrast, dictionaries are more general collections of words.

An abbreviation is a shortened version of an existing word, such as Dr. for Doctor. In contrast, an acronym uses the first letter of each word to create a wholly new word, such as UNESCO (an acronym for the United Nations Educational, Scientific and Cultural Organization).

As a rule of thumb, write the explanation in full the first time you use an acronym or abbreviation. You can then proceed with the shortened version. However, if the abbreviation is very common (like PC, USA, or DNA), then you can use the abbreviated version from the get-go.

Be sure to add each abbreviation in your list of abbreviations !

If you only used a few abbreviations in your thesis or dissertation , you don’t necessarily need to include a list of abbreviations .

If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimizing confusion about abbreviations unfamiliar to your reader.

A list of abbreviations is a list of all the abbreviations that you used in your thesis or dissertation. It should appear at the beginning of your document, with items in alphabetical order, just after your table of contents .

Your list of tables and figures should go directly after your table of contents in your thesis or dissertation.

Lists of figures and tables are often not required, and aren’t particularly common. They specifically aren’t required for APA-Style, though you should be careful to follow their other guidelines for figures and tables .

If you have many figures and tables in your thesis or dissertation, include one may help you stay organized. Your educational institution may require them, so be sure to check their guidelines.

A list of figures and tables compiles all of the figures and tables that you used in your thesis or dissertation and displays them with the page number where they can be found.

The table of contents in a thesis or dissertation always goes between your abstract and your introduction .

You may acknowledge God in your dissertation acknowledgements , but be sure to follow academic convention by also thanking the members of academia, as well as family, colleagues, and friends who helped you.

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .  

In a thesis or dissertation, the discussion is an in-depth exploration of the results, going into detail about the meaning of your findings and citing relevant sources to put them in context.

The conclusion is more shorter and more general: it concisely answers your main research question and makes recommendations based on your overall findings.

In the discussion , you explore the meaning and relevance of your research results , explaining how they fit with existing research and theory. Discuss:

• Your  interpretations : what do the results tell us?
• The  implications : why do the results matter?
• The  limitation s : what can’t the results tell us?

The results chapter or section simply and objectively reports what you found, without speculating on why you found these results. The discussion interprets the meaning of the results, puts them in context, and explains why they matter.

In qualitative research , results and discussion are sometimes combined. But in quantitative research , it’s considered important to separate the objective results from your interpretation of them.

Results are usually written in the past tense , because they are describing the outcome of completed actions.

The results chapter of a thesis or dissertation presents your research results concisely and objectively.

In quantitative research , for each question or hypothesis , state:

• The type of analysis used
• Relevant results in the form of descriptive and inferential statistics
• Whether or not the alternative hypothesis was supported

In qualitative research , for each question or theme, describe:

• Recurring patterns
• Significant or representative individual responses
• Relevant quotations from the data

Don’t interpret or speculate in the results chapter.

To automatically insert a table of contents in Microsoft Word, follow these steps:

• Apply heading styles throughout the document.
• In the references section in the ribbon, locate the Table of Contents group.
• Click the arrow next to the Table of Contents icon and select Custom Table of Contents.
• Select which levels of headings you would like to include in the table of contents.

Make sure to update your table of contents if you move text or change headings. To update, simply right click and select Update Field.

All level 1 and 2 headings should be included in your table of contents . That means the titles of your chapters and the main sections within them.

The contents should also include all appendices and the lists of tables and figures, if applicable, as well as your reference list .

Do not include the acknowledgements or abstract in the table of contents.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

In a thesis or dissertation, the acknowledgements should usually be no longer than one page. There is no minimum length.

The acknowledgements are generally included at the very beginning of your thesis , directly after the title page and before the abstract .

Yes, it’s important to thank your supervisor(s) in the acknowledgements section of your thesis or dissertation .

Even if you feel your supervisor did not contribute greatly to the final product, you must acknowledge them, if only for a very brief thank you. If you do not include your supervisor, it may be seen as a snub.

In the acknowledgements of your thesis or dissertation, you should first thank those who helped you academically or professionally, such as your supervisor, funders, and other academics.

Then you can include personal thanks to friends, family members, or anyone else who supported you during the process.

Dissertation 101: Tips for researching and writing a doctoral dissertation

By Elizabeth Exline

When Rose Lorenzo got close to finishing her  master’s degree  at University of Phoenix (UOPX), she came to a crossroads. She could walk away with her degree and focus on building her company,  Lorenzo Financial , or she could scratch the itch for more academic knowledge and pursue her doctorate.

Lorenzo chose the latter. (And  still  managed to build her company, lay the groundwork to  launch a new school  and eventually get accepted to law school.)

“Although I knew what I wanted to study, I wish I had known how to choose the right topic and how to narrow that topic down before I started,” Lorenzo recalls.

Lorenzo, of course, is talking about the  dissertation , that book-length document that’s both the capstone of the doctoral degree and the driving force behind a doctoral program’s years of study and academic research.

But settling on a topic is just one part of a process that can intimidate even the most determined scholar. What’s exactly involved in a dissertation? And what’s the point of one anyway? Here, we take a deeper dive into the dissertation experience.

What is a dissertation?

A dissertation is an academic document prepared by a doctoral student that contains  original research  about a topic. The student identifies the  topic, conducts the research, writes the dissertation and defends it in front of a committee led by a dissertation chair and other doctoral faculty who decide whether the research meets the doctoral level research standards. If it does, the student will successfully complete the doctoral program, have their dissertation published in ProQuest and earn a terminal degree , which means the highest education level that can be earned in a field.

The dissertation, in other words, is important. But why all the fuss in the first place? According to Rodney Luster, PhD, a dissertation can enhance society’s overall  knowledge and understanding about an issue and ignite a person’s area of interest and expertise, as well as enhance that expertise .

Luster is the chair for the Center for Leadership Studies and Organizational Research within the College of Doctoral Studies at University of Phoenix , and he points to his own dissertation by way of example. 

His research concerned what is currently known as vicarious trauma, a phenomenon he witnessed among his college students after the 9/11 attacks. His students hadn’t been anywhere near the attack, and yet he noticed they displayed classic signs of trauma. This piqued his interest.

“I was able to conduct what I understand was the first research study looking at  vicarious trauma  in the general population, and that has opened up a lot of doors,” Luster explains.

Now an expert on the concept, he has seen the phenomenon after subsequent events, such as Hurricane Katrina.

Lorenzo’s research was more tailored to her area of interest. She ultimately whittled down her topic from how leadership impacts entrepreneurial success or failure to how it impacts female entrepreneurs specifically.

Topics, in other words, offer the freedom for students to follow their curiosity and experience with the goal of potentially  solving a problem  or  adding to a field’s body of knowledge .

Practitioner doctorate vs. PhD – 5 things to know before getting started

Dissertation vs. thesis — what's the difference.

Some people may confuse a dissertation with a thesis, but they’re not the same thing. While similar in nature in that they are both the capstone of an academic program, the biggest difference is where a dissertation and a thesis fit in the educational journey. As explained, a doctoral student completes a dissertation, while a thesis is a research paper for a master’s-level student or sometimes within a bachelor’s program. 

There are other differences as well. One is the level of research involved. Often, a thesis is based on existing research. This means that an undergrad or graduate student will compile various research findings to defend a theory or idea in a thesis. A dissertation on the other hand requires doctoral students to conduct, present and defend their own research.

The two documents differ in length too. A thesis is often much shorter and can range from 40 to 60 pages for an undergraduate thesis and from 60 to upward of 100 pages for a master's thesis. A dissertation is 150 to 300 pages, or 80,000 to 100,000 words. As noted, whether it’s presented in front of a panel of faculty or academics as an oral defense is another key difference. This is often required for a dissertation, but oral defense of a thesis may depend on the program or institution.

How to write a dissertation

Figuring out a dissertation topic is a process as individualized as the students in a doctoral degree program. Luster usually encourages candidates to  begin with a title .

“That’s going to be your selling point for everything, and it has to be understandable. It must be concise. It must have a theoretical construct in it. The title will take you a lot of places and will help lead you into the writing process.”

To this Lorenzo adds a less lofty but equally valid cross-check: She learned to really drill down any topic with the question, “ Who cares? ” If there are people who are invested in learning more about the topic (if there are, in other words, people who care), it may warrant further research.

These preliminary exercises lay a solid foundation for the dissertation process, but the actual research and writing can still feel intimidating. Luster, for example, had written a book before starting his dissertation, and points out that a dissertation “is not like any other writing that you’ve done.”

So, where do you start? At UOPX, you start in your first class.

Understanding ACCESS

The dissertation process at UOPX was revamped and rolled out in September 2019, notes Shawn C. Todd-Boone, EdD, the associate dean for ACCESS, research and residency at the College of Doctoral Studies.

Luster says the process was reimagined based on extensive feedback and on a desire to make the process more effective and efficient.

One of the first ways the dissertation process changed was with the development of  ACCESS , an acronym for “ advancing community, critical thought, engagement, scholarship and success .”

This sequence is incorporated into the first three interdisciplinary courses of any doctoral program at UOPX with an eye toward introducing doctoral candidates to what Luster calls a “theoretical mindset.”

The ACCESS program attempts to nurture a culture of inquiry that helps retain doctoral candidates while inspiring them to innovate in their fields, Boone says.

ACCESS, in other words, sets the tone for the entire doctoral process, which is founded on innovation, research and critical thinking.

The five phases of the dissertation

Writing the dissertation occurs in what Luster describes as five phases over the course of different classes. These are:

• Phase 1: Develop a  prospectus , which is an outline of the research project.
• Phase 2: Draft the first chapter of the dissertation, which is known as the  précis .
• Phase 3: Undergo a  concept review  and develop the second chapter.
• Phase 4: Focus on the  proposal , write the third chapter and review chapters one through three.
• Phase 5: Obtain the approval of the  Institutional Review Board , which evaluates research according to the University’s ethical standards.

The uopx difference.

The five phases of the dissertation writing process aren’t ubiquitous. Doctoral students work on a dissertation while going through the program at UOPX — which was very much intentional, according to Boone.

“We have five phases in the dissertation process and a deliverable at the end of each phase to encourage students to finish and to complete on time if they commit to the process,” Boone explains.

This is a notable improvement, according to Lorenzo. “It is more effective to start your research on day one than wait, because it's easier to identify the gap in research and eliminate wasted research time on topics that are not relevant to your study, and [it] helps contribute to the literature review of the study,” she says.

But this process isn’t the only benefit UOPX students enjoy. The doctoral program has several other distinctive features:

• Once upon a time, students interviewed potential research chairs to take on the oversight of their program. The result was stressful, with doctoral candidates often casting a wide net in the hope of securing a chair and then potentially ending up with someone who wasn’t quite the perfect fit. Today, UOPX takes the stress and potential mismatch out of the equation. “Students do not search for  dissertation committee members ,” Boone says. “We assign them.”
• Dissertations from UOPX tend to focus on  functional application  more so than just theory, Luster notes. This means topics have real-world applications, and communities and industries may benefit from the research. For example, one recent dissertation explored the integration of nurse graduates into hospital settings during COVID-19.
• Doctoral candidates have access to  diverse and extensive resources . In addition to comprehensive documentation about the dissertation process at UOPX, candidates can leverage one-on-one appointments with the University’s library staff, engage in workshops with research chairs and seek opportunities to work as research assistants.
• Rather than what Luster calls a sink-or-swim approach, UOPX has invested in a  mentor-driven approach . “I think that makes us largely different and successful with students, especially adult learners,” Luster says.

In the end, that sense of a safety net — both in terms of mentorship and the doctoral community itself — is one of the biggest reassurances doctoral candidates enjoy.

Lorenzo, for example, keeps in touch with a core group of colleagues she met through the program. “No one understands what you’re going through except for [your peers],” she notes.

Or, as Luster puts it: “You don’t have to worry, because you’ll acquire this information along the way, and you have a lot of good people to help you.”

How long is a doctoral dissertation?

Most are 100 to 300 pages and organized by chapters and/or sections and subsections. There are also often requirements for text size, page size and spacing that can depend on your doctoral program.

What are the parts of a dissertation?

A dissertation generally includes a Dissertation Acceptance Certificate, a title page, a copyright statement, an abstract (detailing the objective of the research, the methods and the outcome), a table of contents, the research itself and supplemental information (either as an appendix with charts and tables or as an uploaded file with digital information). Some dissertations include front and back matter, such as acknowledgments, a dedication, a glossary, a bibliography and related features.

Is a dissertation required for a doctorate?

Not always. While most doctoral and PhD degree programs require a dissertation, some don’t, and others require a capstone project.

What's the difference between a PhD and a doctorate?

Individuals who complete a PhD focus on producing new knowledge to contribute to a theory or body of research. Individuals who  complete a practitioner doctorate , on the other hand, focuses on how to apply knowledge to a field or particular issue.

• What Is a PhD Thesis?
• Doing a PhD

This page will explain what a PhD thesis is and offer advice on how to write a good thesis, from outlining the typical structure to guiding you through the referencing. A summary of this page is as follows:

• A PhD thesis is a concentrated piece of original research which must be carried out by all PhD students in order to successfully earn their doctoral degree.
• The fundamental purpose of a thesis is to explain the conclusion that has been reached as a result of undertaking the research project.
• The typical PhD thesis structure will contain four chapters of original work sandwiched between a literature review chapter and a concluding chapter.
• There is no universal rule for the length of a thesis, but general guidelines set the word count between 70,000 to 100,000 words .

What Is a Thesis?

A thesis is the main output of a PhD as it explains your workflow in reaching the conclusions you have come to in undertaking the research project. As a result, much of the content of your thesis will be based around your chapters of original work.

For your thesis to be successful, it needs to adequately defend your argument and provide a unique or increased insight into your field that was not previously available. As such, you can’t rely on other ideas or results to produce your thesis; it needs to be an original piece of text that belongs to you and you alone.

What Should a Thesis Include?

Although each thesis will be unique, they will all follow the same general format. To demonstrate this, we’ve put together an example structure of a PhD thesis and explained what you should include in each section below.

Acknowledgements

This is a personal section which you may or may not choose to include. The vast majority of students include it, giving both gratitude and recognition to their supervisor, university, sponsor/funder and anyone else who has supported them along the way.

1. Introduction

Provide a brief overview of your reason for carrying out your research project and what you hope to achieve by undertaking it. Following this, explain the structure of your thesis to give the reader context for what he or she is about to read.

2. Literature Review

Set the context of your research by explaining the foundation of what is currently known within your field of research, what recent developments have occurred, and where the gaps in knowledge are. You should conclude the literature review by outlining the overarching aims and objectives of the research project.

3. Main Body

This section focuses on explaining all aspects of your original research and so will form the bulk of your thesis. Typically, this section will contain four chapters covering the below:

• your research/data collection methodologies,
• your results,
• a comprehensive analysis of your results,
• a detailed discussion of your findings.

Depending on your project, each of your chapters may independently contain the structure listed above or in some projects, each chapter could be focussed entirely on one aspect (e.g. a standalone results chapter). Ideally, each of these chapters should be formatted such that they could be translated into papers for submission to peer-reviewed journals. Therefore, following your PhD, you should be able to submit papers for peer-review by reusing content you have already produced.

4. Conclusion

The conclusion will be a summary of your key findings with emphasis placed on the new contributions you have made to your field.

When producing your conclusion, it’s imperative that you relate it back to your original research aims, objectives and hypotheses. Make sure you have answered your original question.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

How Many Words Is a PhD Thesis?

A common question we receive from students is – “how long should my thesis be?“.

Every university has different guidelines on this matter, therefore, consult with your university to get an understanding of their full requirements. Generally speaking, most supervisors will suggest somewhere between 70,000 and 100,000 words . This usually corresponds to somewhere between 250 – 350 pages .

We must stress that this is flexible, and it is important not to focus solely on the length of your thesis, but rather the quality.

How Do I Format My Thesis?

Although the exact formatting requirements will vary depending on the university, the typical formatting policies adopted by most universities are:

What Happens When I Finish My Thesis?

After you have submitted your thesis, you will attend a viva . A viva is an interview-style examination during which you are required to defend your thesis and answer questions on it. The aim of the viva is to convince your examiners that your work is of the level required for a doctoral degree. It is one of the last steps in the PhD process and arguably one of the most daunting!

For more information on the viva process and for tips on how to confidently pass it, please refer to our in-depth PhD Viva Guide .

How Do I Publish My Thesis?

Unfortunately, you can’t publish your thesis in its entirety in a journal. However, universities can make it available for others to read through their library system.

If you want to submit your work in a journal, you will need to develop it into one or more peer-reviewed papers. This will largely involve reformatting, condensing and tailoring it to meet the standards of the journal you are targeting.

Format Requirements for Your Dissertation or Thesis

Main navigation.

The final dissertation or thesis manuscript must have a ready-for-publication appearance and standard features.

The Office of the University Registrar does not endorse or verify the accuracy of any dissertation or thesis formatting templates that may be available to you.

It is your student responsibility to make sure that the formatting meets these requirements. Introductory material, text, and appendices must all be clearly and consistently prepared and must meet all of the specifications outlined below.

Once you upload and submit your dissertation or thesis in Axess, and it has been approved by the university, the submission is considered final and no further changes are permitted.

The digital file of the dissertation or thesis, which is sent to Stanford Libraries for cataloging, must meet certain technical requirements to ensure that it can be easily accessed by readers now and into the future. 

Follow the specifications outlined below.

Style and Format

Word and text divisions, style guides, content and layout, special instructions for d.m.a. students, order and content, page orientation, embedded links, supplementary material and publishing, supplementary material, scholarly reference, published papers and multiple authorship, use of copyrighted material, copyrighting your dissertation, file security and file name, stanford university thesis & dissertation publication license.

Pages should be standard U.S. letter size (8.5 x 11 inches).

In order to ensure the future ability to render the document, standard fonts must be used. 

For the main text body, type size should be 10, 11, or 12 point. Smaller font sizes may be used in tables, captions, etc. 

The font color must be black. 

Font Families

Acceptable font styles include:

• Times New Roman (preferred)
• Courier, Courier Bold, Courier Oblique, Courier Bold-Oblique;
• Helvetica, Helvetica Bold, Helvetica Oblique, Helvetica Bold-Oblique;
• Times, Times Bold, Times Italic, Times Bold-Italic;
• Computer Modern (or Computer Modern Roman).

Note: Do not use script or ornamental fonts. Do not use proprietary fonts.

If you use mathematical or other scientific notation in your dissertation or thesis using a font other than Symbol, you must embed the font into the PDF that is submitted to the university. 

Inner margins (left edge if single-sided; right edge for even-numbered pages, and left edge for odd-numbered pages if double-sided) must be 1.5 inches. All other margins must be one inch.

Pagination, headers, and/or footers may be placed within the margin, but no closer than one-half inch from the edge of the page.

For double-sided copies, 1.5 inches must be maintained as the inner margin. Margin requirements should apply to the entire document, including the title page.

The main body text of the manuscript should be one-and-a-half or double-spaced lines, except where conventional usage calls for single spacing, such as footnotes, indented quotations, tables, appendices, etc.

Words should be divided correctly at the end of a line and may not be divided from one page to the next. Use a standard dictionary to determine word division. 

Avoid short lines that end a paragraph at the top of a page, and any heading or subheading at the bottom of a page that is not followed by text.

The dissertation and thesis must be in English. 

Language Exceptions for Dissertations Only

Approval for writing the dissertation in another language is normally granted only in cases where the other language or literature in that language is also the subject of the discipline. 

Exceptions are granted by the school dean upon submission of a written request from the chair of your major department. Approval is routinely granted for dissertations in the Division of Literature, Cultures, and Languages within department specifications.

Prior to submitting in Axess, you must send a copy of the approval letter (or email message chain) from the department dean to [email protected]    

Dissertations written in another language must include an extended summary in English (usually 15 to 20 pages in length). In this case, you should upload your English summary as a supplemental file, during Step 4 of the online submission process.

Select a standard style approved by your department or dissertation advisor and use it consistently. 

Some reliable style guides are:

• K.A. Turabian’s A Manual for Writers of Term Papers, 
• Theses and Dissertations (University of Chicago Press), and 
• the MLA Handbook for Writers of Research Papers, Theses, and Dissertations (Modern Language Association).

If you are a student in the Doctor of Musical Arts program, you may submit musical scores formatted at 11 x 17 inches in size. 

If you are submitting a performance as your dissertation, submit the audio file in WAV format as a supplemental file. 

Note: The maximum file size accepted for submission is 100 MB. If a performance recording exceeds the maximum file size, break the file into multiple files and submit the parts individually as supplemental files.

Your dissertation or thesis must contain the following sections. All sections must be included in a single digital file for upload.

• Title Page — The format must be followed exactly. View these title page examples for Ph.D. Dissertation and this title page sample for an Engineer Thesis . Use uppercase letters. The title of the dissertation or thesis should be a meaningful description of the content of the manuscript. Use word substitutes for formulas, symbols, superscripts, subscripts, Greek letters, etc. The month and year must be the actual month and year in which you submit your dissertation or thesis electronically to the university. (Note: A student who submits in Autumn quarter is conferred his/her degree in the following calendar year.)
• Copyright Page — The dissertation or thesis PDF uploaded in Axess should not contain a copyright page. The copyright page will be created automatically by the online submission system and inserted into the file stored by Stanford Libraries.
• Signature Page — The dissertation or thesis PDF uploaded in Axess should also not contain a signature page. The submission process has moved away from ink-signatures, so a digital facsimile of the signature page will be created automatically by the online submission system and inserted into the dissertation or thesis in its final format stored by Stanford Libraries.
• Abstract — An abstract may be included in the preliminary section of the dissertation or thesis. The abstract in the body of the dissertation or thesis follows the style used for the rest of the manuscript and should be placed following the signature page. There is no maximum permissible length for the abstract in the dissertation or thesis.    Dissertation authors must enter an abstract using the online submission form for uploading the digital dissertation or thesis file to the library. This abstract, which will be indexed for online searching, must be formatted in plain text (no HTML or special formatting). It should be a pithy and succinct version of the abstract included in the dissertation or thesis itself.
• Preface, an Acknowledgment, or a Dedication.   This is optional.
• Table of Contents – Include page references.
• List of Tables –  Include titles and page references. This list is optional.
• List of Illustrations – Include titles and page references. This list is optional
• Introduction/Main body – Include suitable, consistent headings for the larger divisions and more important sub-divisions.
• Appendices.   This is optional.
• Bibliography or List of References.

Except for the title page, which counts as 'i' but is not physically numbered, each page of the manuscript, including all blank pages, pages between chapters, pages with text, photographs, tables, figures, maps, or computer code must be assigned a number. 

Consistent placement of pagination, at least one-half inch from the paper’s edge, should be used throughout the manuscript.

Follow these pagination instructions exactly:

• For the preliminary pages, use small Roman numerals (e.g., iv, v, vi).
• The title page is not physically numbered, but counts as page i.
• Keep in mind that a copyright page ii and augmented signature page iii (based off your student record) will automatically be inserted to your manuscript during submission.  This means you must ensure to remove pages ii and iii from your dissertation or thesis.
• Failing to remove pages ii and iii is most common formatting mistake: you must remove your copyright page ii and signature page iii from the pdf file before you submit your dissertation or thesis, and begin pagination on your abstract with page number "iv". If the document is formatted for double-sided printing with each section starting on the right page, then pagination will begin on a blank page (page"iv") and the Abstract should be numbered as page "v", and so forth.
• For the remainder of the manuscript, starting with the Introduction or Chapter 1 of the Main Body, use continuous Arabic pagination only (1, 2, 3, etc) for text, illustrations, images, appendices, and the bibliography. Remember to start with Arabic numbered page 1, as this is not a continuation of the Roman numeral numbering from the preliminary pages.
• The placement of page numbers should be consistent throughout the document.

For text, illustrations, charts, graphs, etc., printed in landscape form, the orientation should be facing away from the bound edge of the paper.

Images (color, grayscale, and monochrome) included in the dissertation or thesis should be clearly discernible both on screen and when printed. The dimensions should not exceed the size of the standard letter-size page (8.5” x 11”).

Image resolution should be 150 dots per inch (dpi), though resolutions as low as 72 dpi (and no lower) are acceptable. 

The format of images embedded in the PDF should be JPEG or EPS (the format JPEG2000 is also acceptable when it is supported in future versions of the PDF format). GIF and PNG are not preferred image file formats.

Large images, including maps and charts or other graphics that require high resolution, should not be included in the main dissertation or thesis file. Instead, they can be submitted separately as supplemental files and formatted in other formats as appropriate. 

Multimedia, such as audio, video, animation, etc., must not be embedded in the body of the dissertation or thesis. These media types add size and complexity to the digital file, introducing obstacles to users of the dissertation or thesis who wish to download and read (and “play back”) the content, and making it more difficult to preserve over time.

If you wish to include multimedia with your submission, upload the media separately as a stand-alone file in an appropriate media format. See Supplementary Material section below.

It is acceptable to include “live” (i.e., clickable) web URLs that link to online resources within the dissertation or thesis file. Spell out each URL in its entirety (e.g., http://www.stanford.edu ) rather than embedding the link in text (e.g., Stanford homepage ). By spelling out the URL, you improve a reader’s ability to understand and access the link reference.

Supplementary material may be submitted electronically with the dissertation or thesis. This material includes any supporting content that is useful for understanding the dissertation or thesis, but is not essential to the argument. It also covers core content in a form that can not be adequately represented or embedded in the PDF format, such as an audio recording of a musical performance.

Supplementary materials are submitted separately than the dissertation or thesis file, and are referred to as supplemental files.

A maximum of twenty supplemental files can be submitted. There are no restrictions on the file formats. The maximum file size is 1 GB.

You are encouraged to be judicious about the volume and quality of the supplemental files, and to employ file formats that are widely used by researchers generally, if not also by scholars of the discipline.

The following table outlines recommended file formats for different content types. By following these recommendations, the author is helping to ensure ongoing access to the material.

After uploading each supplemental file, it is important to enter a short description or label (maximum 120 characters for file name and the description). This label will be displayed to readers in a list of the contents for the entire submission.

If copyrighted material is part of the supplementary material, permission to reuse and distribute the content must be obtained from the owner of the copyright. Stanford Libraries requires copies of permission letters (in PDF format) to be uploaded electronically when submitting the files, and assumes no liability for copyright violations. View this sample permission letter .

System restrictions allow for a maximum of 10 individually uploaded permission files. If you have more than 10 permission files we recommend combining all permission letters into a single PDF file for upload.

In choosing an annotation or reference system, you should be guided by the practice of your discipline and the recommendations of your departments. In addition to the general style guides listed in the Style section above, there are specific style guides for some fields. When a reference system has been selected, it should be used consistently throughout the dissertation or thesis. The placement of footnotes is at your discretion with reading committee approval.

An important aspect of modern scholarship is the proper attribution of authorship for joint or group research. If the manuscript includes joint or group research, you must clearly identify your contribution to the enterprise in an introduction.

The inclusion of published papers in a dissertation or thesis is the prerogative of the major department. Where published papers or ready-for-publication papers are included, the following criteria must be met:

• There must be an introduction that integrates the general theme of the research and the relationship between the chapters. The introduction may also include a review of the literature relevant to the dissertation or thesis topic that does not appear in the chapters.
• Multiple authorship of a published paper should be addressed by clearly designating, in an introduction, the role that the dissertation or thesis author had in the research and production of the published paper. The student must have a major contribution to the research and writing of papers included in the dissertation or thesis.
• There must be adequate referencing of where individual papers have been published.
• Written permission must be obtained for all copyrighted materials. Letters of permission must be uploaded electronically in PDF form when submitting the dissertation or thesis. 
• The published material must be reformatted to meet the university's format requirements (e.g., appropriate margins and pagination) of the dissertation. The Office of the University Registrar will approve a dissertation or thesis if there are no deviations from the normal specifications that would prevent proper dissemination and utilization of the dissertation or thesis. If the published material does not correspond to these standards, it will be necessary for you to reformat that portion of the dissertation or thesis.
• Multiple authorship has implications with respect to copyright and public release of the material. Be sure to discuss copyright clearance and embargo options with your co-authors and your advisor well in advance of preparing your thesis for submission.

If copyrighted material belonging to others is used in your dissertation or thesis or is part of your supplementary materials, you must give full credit to the author and publisher of the work in all cases, and obtain permission from the copyright owner for reuse of the material unless you have determined that your use of the work is clearly fair use under US copyright law (17 USC §107). 

The statute sets out four factors that must be considered when assessing Fair Use:

• the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purpose;
• the nature of the copyrighted work;
• the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
• the effect of the use upon the potential market for or value of the copyrighted work.

The Association of American University Presses requires permission for any quotations that are reproduced as complete units (poems, letters, short stories, essays, journal articles, complete chapters or sections of books, maps, charts, graphs, tables, drawings, or other illustrative materials). You can find this guideline and other detailed information on Fair Use at http://fairuse.stanford.edu . 

If you are in doubt, it is safest to obtain permission. Permission to use copyrighted material must be obtained from the owner of the copyright. Stanford Libraries requires copies of permission letters (in PDF format) to be uploaded electronically when submitting the dissertation or thesis, and assumes no liability for copyright violations. For reference, view this sample permission letter .

Copyright protection is automatically in effect from the time the work is in fixed form. A proper copyright statement consisting of the copyright symbol, the author’s name, year of degree conferral, and the phrase “All Rights Reserved” will be added automatically to the dissertation or thesis in its final form.

Registration of copyright is not required, but it establishes a public record of your copyright claim and enables copyright owners to litigate against infringement. You need not register your copyright with the U.S. Copyright Office at the outset, although registration must be made before the copyright may be enforced by litigation in case of infringement. 

Early registration does have certain advantages: it establishes a public record of your copyright claim, and if registration has been made prior to the infringement of your work, or within three months after its publication, qualifies you to be awarded statutory damages and attorney fees in addition to the actual damages and profits available to you as the copyright owner (should you ever have to sue because of infringement).

For more information about copyright, see the Stanford Libraries' resource on Copyright Considerations .

For further information on Registration of Copyright, see https://www.copyright.gov/registration/ .

Do not require a password to make changes to your submitted PDF file, or apply other encryption or security measures. Password-protected files will be rejected.

The file name and description will be printed on a page added to your dissertation or thesis, so choose a file name accordingly.

Important note: File names may only consist of alphanumeric characters, hyphen, underscore, at sign, space, ampersand, and comma – before the ending period and file extension.  Specifically,

• A file name cannot start with a space, period (nor contain a period), underscore, or hyphen.
• Files names must be 120 characters or less.

Why is a PhD thesis typically 150 pages? [closed]

I just don't understand why the overall findings & implications of a PhD cannot be communicated in the style of a research paper?

Succinctness is a virtue in a field characterised by time pressure.

The research output is equal to or less than that of a 3 year postdoc - which is always communicated as a research paper.

Just seems like added embellishment for the sake of embellishment.

• 20 What am I missing? A lot actually. The length of a PhD dissertation varies greatly by field, university, and department.

I don't know where your 150 page idea comes from since I have never heard this as a guideline. However, in my field, "staple theses" are common, composed of roughly 3 papers stapled together (either already published or publishable drafts), with an added introduction and conclusion that tie the works together and may get a bit deeper into background than is acceptable in a published manuscript.

Therefore, they must be at least the length of three research papers, and aren't typically all that much longer than that. However, theses are also typically formatted in a longer form, more similar to the original word-processed manuscript, whereas journal articles are composed in a dense, newspaper-like format. Figures may have their own pages. In sum, a manuscript that is 10-15 published pages can easily be 30-50 pages in this format.

No embellishment necessary to get to 150 pages.

I'd also add that a post doc in my field who only produced 1 paper in 3 years would probably have their next job in industry; a graduate student with only one paper will have been quite disappointing (it may happen that only one paper is publishable due to being scooped or unexpected failures, but even those outcomes can be part of a thesis). Not necessarily, it's possible that paper could be highly impactful, and might be reasonable in some subfields, but generally that would not be a suitable output for an academic career.

Edit: decided to pull up my own thesis from the archives. 230 pages. Of those, 53 pages are "thesis-only" pages; the other 177 pages are verbatim copies from 2 published papers and a third draft manuscript which was later revised and published, all reformatted to fit the thesis formatting requirements. Of the remaining 53 pages of "fluff," 6 pages are title/contents/acknowledgements/abstract, and about 19 are references for the introduction/conclusion chapters, so about 28 extra pages of generously spaced writing, to be treated as "embellishment" if you wish, or alternatively, to provide enough background and context for the work for someone familiar with the field but not previously familiar with my research area, such as members of my thesis committee besides my advisor.

In summary, even if my thesis had nothing but 3 published/publishable manuscripts, it would already be >150 pages.

• I recognise that PhD theses vary in length; however in general theses have a substantially higher word count than a research publication. –  Asymptotic Tri Commented Jul 22, 2019 at 19:14
• Number of papers as a marker of progress is annoying too. It is possible to publish 100 papers without changing the world in any meaningful way. –  Asymptotic Tri Commented Jul 22, 2019 at 19:16
• 3 @AsymptoticTri Yes, they do, and my answer explains why, at least in my area, they would typically have at least 3 times as many words as a research publication, plus a few extra pages of context. I am also in biology. –  Bryan Krause ♦ Commented Jul 22, 2019 at 19:16
• 12 It is possible to publish 100 papers without changing the world in any meaningful way — If changing the world in a meaningful way were a requirement for a successful PhD thesis, there would be very very very few PhDs, almost all awarded posthumously. –  JeffE Commented Jul 22, 2019 at 20:46

Succinctness may be a virtue, but page limits means that papers are often overly terse. They also commonly leave out important information, helpful steps, and additional but less eye catching results. The presentation and style of a paper is also often geared towards experts in a field, while you have more freedom to be pedagogical and explicit in a dissertation. Factor in a double-spaced one-column format and some front matter, and it's easy to get to 150 pages and beyond.

In fact, one of my papers during the PhD (physics) was five pages long when published, plus references (not counted in page limit). Six pages of supplemental material was deposited along with the paper, for a total of 11 pages. The corresponding chapter in the dissertation is 46 pages long, with some details still relegated to appendices... The main difference in presentation, however, isn't the length or layout - it's that I attempted to make the description more self-contained. A new graduate student may actually get a reasonable idea of the background and calculations from reading this chapter and the introduction. In contrast, there's no way the same grad student could get all details from the paper and be able to reproduce the calculations without following a bunch of references, well unless they already were an expert . And if you do read those papers, the amount of material to go through would quickly exceed 150 pages anyway.

Yes, many dissertations could be made more compact, but why? The dissertation is a rare opportunity where you don't have to compromise style or contents. It's an opportunity to provide an alternate description than already exists in preprints or published papers that can be useful to another audience. It's also a place where you can make deposit certain results, derivations, proofs or procedures that don't fit elsewhere in explicit form for later use by yourself as well as others. So if you want to write a shorter dissertation yourself, that's alright, but avoid judging others for trying to be more pedagogical than the journal paper form allows.

• @AsymptoticTri I'm happy it helped. –  Anyon Commented Jul 24, 2019 at 12:36

Your question includes a number of assumptions, which are not universal and may be simply wrong for some areas.

• You probably know that John Nash had one of the shortest PhD theses with only 26 pages and 2 references. PhD theses of 300+ pages are also not unusual, particularly in humanities.
• I would expect a postdoctoral researcher in Mathematics to participate / contribute to at least 1 paper per year. I know of colleagues in Engineering / Computer Science for whom this expectation seems very low - a postdoctoral researcher in their group would put their name on 3-5 outputs per year.

Number of pages, as well as the number of outputs, is an very poor metric of research effort and performance. Some universities may put an upper boundary on the number of pages to make sure that their supervisors are not overwhelmed with the amount of material they have to read and comment on during the supervision (after all, Universities want their staff to do a lot of work apart of supervising the particular student). I don't think that the lower boundary is very usual.

Having said this, there is definitely an expectation that a PhD theses should contain a detailed introduction and thorough literature review. After all, a PhD student should study the area and then train themselves to become a professional researcher in this area. In contrast, a postdoctoral researcher is already expected to be trained and their work is only to do novel research. For a PhD student, a lot of emphasis is on studying the methodology, and writing about it takes time and a significant number of pages.

Finally, compare the number of references: a typical journal paper could have 30, while a PhD theses can easily have 300. This clearly shows that the scope of a PhD theses is much wider than the scope of an academic research paper, while a paper may be more focused and deep.

• 7 @AsymptoticTri The content in the intro and lit review of a paper is nowhere near as detailed as those in a thesis should be. That's the whole point: the candidate needs to be able to show that they understand the breadth of the field and how their research topic fits into that, as well as give an introduction to the broad picture so that a non-expert could understand the thesis. Instead, papers show the depth of knowledge in a very narrow area. –  astronat supports the strike Commented Jul 22, 2019 at 19:51

• 2 @AsymptoticTri Because, as many answers have already stated, their PhD work is usually more than can be effectively communicated in a single paper. Or perhaps more to the point, because a single paper is usually considered insufficient evidence of being a successful researcher. –  JeffE Commented Jul 24, 2019 at 0:05

How Many Pages is a Thesis or Dissertation: Masters to PhD

• by Judy Jeni
• January 30, 2024

A thesis is a written document by a student in support of candidature for professional qualifications or academic degrees.

It presents the student’s research and findings. A thesis has its structure and presentation styles. But one may ask, how many pages is a thesis?

Furthermore, do the college, master’s, and Ph.D. projects have the same page numbers? A typical thesis paper has a title page, abstract, and table of contents. We have chapters like introduction, literature review, methodology, results, discussions, and a reference section.

How Many Pages is a General Thesis

From experience, a thesis, in general, is between 40-80 pages long, excluding the bibliography pages. This length however depends on the level of study, the type of research to be conducted, and the expectations of the institution you are presenting it to.

Also, the structure difference is attributed to the areas of study—for instance, arts, technology, social sciences, humanities, sciences, etc.

In addition, the method of analysis contributes to the increase or decrease of the page numbers. The format of your thesis is presented in three outlines:

• The first outline consists of the abstract, table of content, and introduction.
• The second outline has the methods of research you used, your findings, and your discussion of the same.
• The last outline has your research conclusions, accompanying recommendations, and your list of references.

Even though there are no set standards on the number of pages, the quality of your work precedes your quantity.

How Many Pages is a Thesis for College

A college thesis is from 40 pages and above so that it can cover the contents of the topic and research being undertaken. However, this length depends on your area of study and the teacher’s guidelines dictate the structure of your writing. Although each thesis is different, they all have common elements.

The typical outline has an abstract, an introduction, research methods, and findings, and lastly, a conclusion and a bibliography section.

To be able to have your paper have all the necessary points and required length;

• Start by arranging your paper as a logical argument before you start to write.
• Have figures that illustrate your argument
• The background of your argument is your introduction, describe the information used in your argument as the points in your observation, analyze your issues and come up with your conclusion.
• Outline the main elements in sections and subsections
• Start to write your college thesis.

How Many Pages is a Thesis for Masters or PhD

On average, a master’s thesis or a PhD dissertation is between 120 pages and 200 pages long without counting the bibliography and the appendices. However, the length of a thesis is determined by the depth of your research and the technical nature of the research being conducted.

Also, the literature review and discussion sections determine the length of the project. Always remember to write for brevity rather than length.

No matter the length of your dissertation, always remember that you need to follow the instructions and be brief. Your thesis aims to have all the necessary information discussing your work and supporting your interpretation.

A master’s thesis is close to a doctoral dissertation, but it is shorter and has a narrow focus on the topic of discussion. To understand the length of a thesis for both master’s and Ph.D., first, let’s look at the parts that carry the length.

Purpose and Significance of your Study

In chapter one, you start by outlining the purpose of your study and its significance. The significance is shown by explaining how the study adds to the theoretical knowledge and its practical significance.

For a Ph.D. thesis, students discuss how their research makes a unique contribution to the knowledge in their disciplines.

Additionally, they discuss the significance of their study to the general people.

Chapter one of your thesis should be well developed to give you a clear focus and direction for your entire thesis.

Literature Review

Chapter two discusses the literature review. Here you discuss the theoretical framework of your literature. Besides discussing what other researchers have found, you should analyze and discuss your body of knowledge.

The aim here should be to expound on what is known and what is not known on your topic of discussion. The above will assist you in writing your research question or the hypothesis.

Methodology

Chapter three expounds on your methodology. Discuss the methods you used to gather data for your thesis. In addition, you will write about how you analyzed your data.

Start by discussing the method you used to gather your raw data and why your preference was appropriate. Remember to cite the reference literature on the technique.

Although this chapter varies based on the method and analysis technique used, give a detailed procedure you used to gather and analyze your data.

The following are the subtopics of this section;

• Description of research design
• Description of population and justification for sampling method used
• Describe the method or instrument of making observations and its administration
• Description of data analysis, tests performed, and statistical analysis. Also, discuss the qualitative or historical research.

In chapter four discuss the results from your data analysis only. Do not include other research findings or the implications of your findings.

Start by explaining any descriptive analysis. For example, factory analysis or reliability tests that were conducted.

Continue to talk about the findings of your hypothesis test. Extensively, use tables and figures to represent numerical data from your findings.

The qualitative and historical research is organized by the themes found in your research.

Lastly, chapter five shows what your findings mean concerning the theoretical knowledge of your topic. Although this chapter is somehow skimmed, it should be seen as important as it answers the question “so what…”

Start by explaining your findings concerning the theoretical passage presented in the literature review. With qualitative research, you may as well introduce new literature. Alongside,doctoral students should demonstrate the pedagogical implications of the findings to mass education.

The chapter also continues to discuss the limitations encountered in your research. Alongside, propose areas of future research. Have a solid final closure with a brief conclusion.

Factors Determining the Length of a Thesis

The following factors determine the length of your thesis

Your Area of Study

Your area of learning or the discipline dictates how long your thesis will be. The subject determines whether you will write longer literature reviews or collection of more data.

It should be noted that this will also affect the time it takes to complete your thesis because the demands of your subject will eat on your valuable time. Both lead to a longer or a shorter thesis or dissertation.

Nature of Your Project

The scope of your thesis will reflect on the length of your thesis. For example, the introduction length is dictated by the total word count of your thesis.

It should not exceed ten percent of your total word count. As an illustration, if your total words are eight thousand, your introduction should be up to 800 words.

Tips on How to Lengthen your Thesis

There are numerous ways you can use to reach the required word count or required pages.  You may increase the margin of your paper, but you might anger your professor. The following are better ways of lengthening your thesis.

1. Ensure you have included Everything

Check whether you have answered all the questions required by your research. In addition, include as much background material as possible. This will give you data that you will use to increase your word count.

Finding something that you have forgotten could be the reason why your thesis is shorter.

2. Intertwine Transitional Phrases in your Writing

Using transitional phrases is a natural way of lengthening your thesis. In addition, they help your reader follow through as they can connect your thoughts. Transition phrases assist you in moving from one idea to the next clearly and concisely.

3. Use Quotations

When referring to other people’s work, you use quotation marks.

Besides spicing your thesis, you can increase the size of your thesis.

Incorporating other writers’ work strengthens your arguments.

4. Review Your Introduction and Conclusion

Ideas come to you as you reread your work. Go through your introduction again to check whether there is a point you have left behind.

Ensure you have expounded on your points, and you are sure your reader will thoroughly understand your points. Also, do the same to your conclusion.

5. Spell Out Numbers or Contractions

Instead of writing numbers in figures, write them in words. Substitute “8” by writing eight. Instead of “we’re,” write the whole word- we are. However, this is limited by the style you are required to submit your thesis on.

6. Use Break-Up Paragraphs

Your work could be comprised of long paragraphs; break them to ensure a paragraph has fewer sentences. Besides increasing your thesis pages, you will make your work more readable. People prefer reading broken-down content.

What is a Ph.D. Dissertation?

[I wrote this in 1993 as a letter to a student concerning a draft of his dissertation. In 2003 I edited it to remove some specific references to the student and present it as a small increment to the information available to my grad students. In 2023 I made small edits for grammar and to expand coverage.--spaf]

Let me start by reviewing some things that may seem obvious:

• Your dissertation is part of the requirements for a PhD. The research, theory, experimentation, et al. also contribute. One does not attempt to capture everything in one's dissertation.
• The dissertation is a technical work that documents and proves one's thesis. It is intended for a technical audience and must be clear and complete but not necessarily exhaustively comprehensive. Also note -- experimental data, if used, is not the proof -- it is evidence. The proof is presented as an analysis and critical presentation. Generally, every statement in your dissertation must be common knowledge, supported by citation to technical literature, or original results proved by the candidate (you). Each of those statements must directly relate to the proof of the thesis, or else they are unnecessary.

Let's revisit the idea of the thesis itself. It is a hypothesis, a conjecture, or a theorem. The dissertation is a formal, stylized document used to argue your thesis. The thesis must be significant, original (no one has yet demonstrated it to be true), and it must extend the state of scientific knowledge.

The first thing you need to do is to come up with no more than three sentences that express your thesis. Your committee must agree that your statements form a valid thesis statement. You, too, must be happy with the statement -- it should be what you will tell anyone if they ask you what your thesis is (few people will want to hear an hour's presentation as a response).

Once you have a thesis statement, you can begin developing the dissertation. The abstract, for instance, should be a one-page description of your thesis and how you present the proof of it. The abstract should summarize the results of the thesis and should stress the contributions to science made thereby.

Perhaps the best way to understand how an abstract should look would be to examine the abstracts of several dozen dissertations that have already been accepted. Our university library has a collection of them. This is a good approach to see how an entire dissertation is structured and presented. MIT Press has published the ACM doctoral dissertation award series for decades, so you may find some of those to be good examples to read -- they should be in any large technical library.

The dissertation itself should be structured into 4 to 6 chapters. The following is one commonly-used structure:

• Introduction. Provide an introduction to the basic terminology, cite appropriate background work, and briefly discuss related work that has already covered aspects of the problem.
• Abstract model. Discuss an abstract model of what you are trying to prove. This chapter should not discuss any specific implementation (see below)
• Validation of model/proof of theorems. This is a chapter showing proof of the model. It could be a set of proofs or a discussion of the construction and validation of a model or simulation to gather supporting data.
• Measurements/data. This would present data collected from actual use, simulations, or other sources. The presentation would include analysis to show support for the underlying thesis.
• Additional results. In some work, there may be secondary confirmation studies, or it might be the case that additional significant results are collected along the way to the proof of the central thesis. These would be presented here.
• Conclusions and future work. This is where the results are all tied together and presented. Limitations, restrictions, and special cases should be clearly stated here, along with the results. Some extensions as future work may also be described.

Let's look at these in a little more detail

Chapter I, Introduction. Here, you should clearly state the thesis and its importance. This is also where you define terms and other concepts used elsewhere. There is no need to write 80 pages of background on your topic here. Instead, you can cover almost everything by saying: "The terminology used in this work matches the definitions given in [citation, citation] unless noted otherwise." Then, cite some appropriate works that give the definitions you need. The progress of science is that we learn and use the work of others (with appropriate credit). Assume you have a technically literate readership familiar with (or able to find) standard references. Do not reference popular literature or WWW sites if you can help it (this is a matter of style more than anything else -- you want to cite articles in refereed conferences and journals, if possible, or in other theses).

Also, in the introduction, you want to survey any related work that attempted something similar to your own or has a significant supporting role in your research. This should refer only to published references. You cite the work in the references, not the researchers themselves. E.g., "The experiments described in [citation] explored the foo and bar conditions, but did not discuss the further problem of baz, the central point of this work." You should not make references such as this: "Curly, Moe, and Larry all believed the same in their research [CML53]" because you do not know what they believed or thought -- you only know what the paper states. Every factual statement you make must have a specific citation tied to it in this chapter, or else it must be common knowledge (don't rely on this too much).

Chapter II. Abstract Model. Your results are to be of lasting value. Thus, the model you develop and write about (and indeed, that you defend) should have lasting value. Thus, you should discuss a model not based on Windows, Linux, Ethernet, PCMIA, or any other technology. It should be generic and capture all the details necessary to overlay the model on likely environments. You should discuss the problems, parameters, requirements, necessary and sufficient conditions, and other factors here. Consider that 20 years ago (ca 1980), the common platform was a Vax computer running VMS or a PDP-11 running Unix version 6, yet well-crafted theses of the time are still valuable today. Will your dissertation be valuable 20+ years from now (ca 2050), or have you referred to technologies that will be of only historical interest?

This model is tough to construct but is the heart of the scientific part of your work. This is the lasting part of the contribution, and this is what someone might cite 50 years from now when we are all using MS Linux XXXXP on computers embedded in our wrists with subspace network links!

Chapters III & IV, Proof.There are basically three proof techniques that I have seen used in a computing dissertation, depending on the thesis topic. The first is analytic, where one takes the model or formulae and shows, using formal manipulations, that the model is sound and complete. A second proof method is stochastic, using statistical methods and measurements to show that something is true in the anticipated cases.

• clearly showing how your implementation model matches the conditions of your abstract model,
• describing all the variables and why you set them as you do,
• accounting for confounding factors, and
• showing the results.

Chapter V. Additional results. This may be folded into Chapter III in some theses or multiple chapters in a thesis with many parts (as in a theory-based thesis). This may be where you discuss the effects of technology change on your results. This is also a place where you may wish to point out significant results that you obtained while seeking to prove your central thesis but which are not supportive of the thesis. Often, such additional results are published in a separate paper.

Chapter VI. Conclusions and Future Work. This is where you discuss what you found from your work, incidental ideas and results that were not central to your thesis but of value nonetheless (if you did not have them in Chapter V), and other results. This chapter should summarize all the important results of the dissertation --- note that this is the only chapter many people will ever read, so it should convey all the important results.

This is also where you should outline some possible future work that can be done in the area. What are some open problems? What are some new problems? What are some significant variations open to future inquiry?

Appendices usually are present to hold mundane details that are not published elsewhere but are critical to the development of your dissertation. This includes tables of measurement results, configuration details of experimental testbeds, limited source code listings of critical routines or algorithms, etc. It is not appropriate to include lists of readings by topic, lists of commercial systems, or other material that does not directly support the proof of your thesis.

Here are some more general hints to keep in mind as you write/edit:

• Adverbs should generally not be used -- instead, use something precise. For example, do not say that something "happens quickly." How fast is quickly? Is it relative to CPU speeds? Network speeds? Does it depend on connectivity, configuration, programming language, OS release, etc? What is the standard deviation?
• As per the above, the use of the words "fast," "slow," "perfect," "soon," "ideal," "lots of," and related should all be avoided. So should "clearly," "obviously," "simple," "like," "few," "most," "large," et al.
• What you are writing is scientific fact. Judgments of aesthetics, ethics, personal preference, and the like should be in the conclusions chapter, if they should be anywhere at all. With that in mind, avoid the use of words such as "good," "bad," "best," and any similar discussion. Also, avoid stating "In fact," "Actually," "In reality," and any similar construct -- everything you are writing must be factual, so there is no need to state such things. If you feel compelled to use one of these constructs, then carefully evaluate what you are saying to ensure you are not injecting relative terms, opinions, value judgments, or other items inappropriate for a dissertation.
• Computers and networks do not have knees, so poor performance cannot bring them to something they do not have. They also don't have hands, so "On the one hand..." is not good usage. Programs don't perform conscious thought (nor do their underlying computers), so your system does not "think" that it has seen a particular type of traffic. Generalizing from this, do not anthropomorphize your IT components!
• Avoid mention of time and environment. "Today's computers" are antiques far sooner than you think. Your thesis should still be true many years from now. If a particular time or interval is necessary, be explicit, as in "Between 1905 and 1920" rather than "Over the last 15 years." (See the difference, given some distance in time?)
• Be sure that any scientist or mathematician would recognize something you claim as proof.
• Focus on the results and not the methodology. The methodology should be clearly described but not the central topic of your discussion in chapters III & IV
• Keep concepts and instances separate. An algorithm is not the same as a program that implements it. A protocol is not the same as the realization of it; a reference model is not the same as a working example, and so on.

As a rule of thumb, a CS dissertation should probably be longer than 100 pages but less than 160. Anything outside that range should be carefully examined with the above points in mind.

Keep in mind that you -- the Ph.D. candidate -- are expected to become the world's foremost expert on your topic area. That topic area should not be unduly broad but must be big enough to be meaningful. Your advisor and committee members are not supposed to know more about the topic than you do -- not individually, at least. Your dissertation is supposed to explain your findings and, along with the defense, demonstrate your mastery of the area in which you are now the leading expert. That does not mean writing everything you know -- it means writing enough about the most important points that others can agree with your conclusions.

Last of all, don't fall into the trap that ties up many candidates and causes some of them to flame out before completion: your thesis does not need to be revolutionary. It simply needs to be an incremental advancement in the field. Few Ph.D. dissertations have ever had a marked impact on the field. Instead, it is the author's set of publications and products of the author that may change the field.

If your dissertation is like most, it will only be read by your committee and some other Ph.D. candidates seeking to build on your work. As such, it does not need to be a masterwork of literature, nor does it need to solve a long-standing problem in computing. It merely needs to be correct, to be significant in the judgment of your committee, and it needs to be complete. We will all applaud when you change the world after graduation. And at that, you will find that many well-known scientists in CS have made their careers in areas different from their dissertation topic. The dissertation is proof that you can find and present original results; your career and life after graduation will demonstrate the other concerns you might have about making an impact.

So get to work!

Word limits and requirements of your Degree Committee

Candidates should write as concisely as is possible, with clear and adequate exposition. Each Degree Committee has prescribed the limits of length and stylistic requirements as given below. On submission of the thesis you must include a statement of length confirming that it does not exceed the word limit for your Degree Committee.

These limits and requirements are strictly observed by the Postgraduate Committee and the Degree Committees and, unless approval to exceed the prescribed limit has been obtained beforehand (see: Extending the Word Limit below), a thesis that exceeds the limit may not be examined until its length complies with the prescribed limit.

Extending the Word Limit

Thesis word limits are set by Degree Committees. If candidates need to increase their word limits they will need to apply for permission.

Information on how to apply (via self-service account) is available on the ‘ Applying for a change in your student status’  page. If following your viva, you are required to make corrections to your thesis which will mean you need to increase your word-limit, you need to apply for permission in the same way.

Requirements of the Degree Committees

Archaeology and anthropology, architecture and history of art, asian and middle eastern studies, business and management, clinical medicine and clinical veterinary medicine, computer laboratory, earth sciences and geography, scott polar institute, engineering, history and philosophy of science, land economy, mathematics, modern and medieval languages and linguistics, physics and chemistry, politics and international studies, archaeology and social anthropology.

The thesis is not to exceed 80,000 words (approx. 350 pages) for the PhD degree and 60,000 words for the MSc or MLitt degree. These limits include all text, figures, tables and photographs, but exclude the bibliography, cited references and appendices. More detailed specifications should be obtained from the Division concerned. Permission to exceed these limits will be granted only after a special application to the Degree Committee. The application must explain in detail the reasons why an extension is being sought and the nature of the additional material, and must be supported by a reasoned case from the supervisor containing a recommendation that a candidate should be allowed to exceed the word limit by a specified number of words. Such permission will be granted only under exceptional circumstances. If candidates need to apply for permission to exceed the word limit, they should do so in good time before the date on which a candidate proposes to submit the thesis, by application made to the Graduate Committee.

Biological Anthropology:

Students may choose between two alternative thesis formats for their work:

either in the form of a thesis of not more than 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The limits include all text, in-text citations, figures, tables, captions and footnotes but exclude bibliography and appendices; or

in the form of a collection of at least three research articles for the PhD degree and two research articles for the MSc or MLitt degree, formatted as an integrated piece of research, with a table of contents, one or more chapters that outline the scope and provide an in-depth review of the subject of study, a concluding chapter discussing the findings and contribution to the field, and a consolidated bibliography. The articles may be in preparation, submitted for publication or already published, and the combined work should not exceed 80,000 words in length for the PhD degree and 60,000 words for the MSc or MLitt degree. The word limits include all text, in-text citations, figures, tables, captions, and footnotes but exclude bibliography and appendices containing supplementary information associated with the articles. More information on the inclusion of material published, in press or in preparation in a PhD thesis may be found in the Department’s PhD submission guidelines.

Architecture:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MSc or MLitt degree. Footnotes, references and text within tables are to be counted within the word-limit, but captions, appendices and bibliographies are excluded. Appendices should be confined to such items as catalogues, original texts, translations of texts, transcriptions of interview, or tables.

History of Art:

The thesis is not to exceed 80,000 words for the PhD and 60,000 words for the MLitt degree. To include: footnotes, table of contents and list of illustrations, but excluding acknowledgements and the bibliography. Appendices (of no determined word length) may be permitted subject to the approval of the candidate's Supervisor (in consultation with the Degree Committee); for example, where a catalogue of works or the transcription of extensive primary source material is germane to the work. Permission to include such appendices must be requested from the candidate's Supervisor well in advance of the submission of the final thesis. NB: Permission for extensions to the word limit for most other purposes is likely to be refused.

The thesis is for the PhD degree not to exceed 80,000 words exclusive of footnotes, appendices and bibliography but subject to an overall word limit of 100,000 words exclusive of bibliography. For the MLitt degree not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography and appendices.

The thesis for the PhD is not to exceed 60,000 words in length (80,000 by special permission), exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

The thesis for the MPhil in Biological Science is not to exceed 20,000 words in length, exclusive of tables, footnotes, bibliography, and appendices. Double-spaced or one-and-a-half spaced. Single or double-sided printing.

For the PhD Degree the thesis is not to exceed 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices. It is normally expected to exceed 40,000 words unless prior permission is obtained from the Degree Committee. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size. The Degree Committee do not consider applications to extend this word limit.

For the Doctor of Business (BusD) the thesis will be approximately 200 pages (a maximum length of 80,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices).

For the MSc Degree the thesis is not to exceed 40,000 words, EXCLUDING bibliography, but including tables, tables of contents, footnotes and appendices.

The thesis is not to exceed 80,000 words including footnotes, references, and appendices but excluding bibliography; a page of statistics shall be regarded as the equivalent of 150 words. Only under exceptional circumstances will permission be granted to exceed this limit. Candidates must submit with the thesis a signed statement giving the length of the thesis.

For the PhD degree, not to exceed 60,000 words (or 80,000 by special permission of the Degree Committee), and for the MSc degree, not to exceed 40,000 words. These limits exclude figures, photographs, tables, appendices and bibliography. Lines to be double or one-and-a-half spaced; pages to be double or single sided.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes and equations, but excluding appendices, bibliography, photographs and diagrams. Any thesis which without prior permission of the Degree Committee exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words for the PhD degree and the MLitt degree, including footnotes, references and appendices but excluding bibliography. Candidates must submit with the thesis a signed statement giving the length of the thesis. Only under exceptional circumstances will permission be granted to exceed this limit for the inclusion of an appendix of a substantial quantity of text which is necessary for the understanding of the thesis (e.g. texts in translation, transcription of extensive primary source material). Permission must be sought at least three months before submission of the thesis and be supported by a letter from the supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

The thesis is not to exceed, without the prior permission of the Degree Committee, 80,000 words for the PhD degree and 60,000 words for the MSc or MLitt degree, including the summary/abstract.  The table of contents, photographs, diagrams, figure captions, appendices, bibliography and acknowledgements to not count towards the word limit. Footnotes are not included in the word limit where they are a necessary part of the referencing system used.

Earth Sciences:

The thesis is not to exceed, without the prior permission of the Degree Committee, 275 numbered pages of which not more than 225 pages are text, appendices, illustrations and bibliography. A page of text is A4 one-and-a-half-spaced normal size type. The additional 50 pages may comprise tables of data and/or computer programmes reduced in size.

If a candidate's work falls within the social sciences, candidates are expected to observe the limit described in the Department of Geography above; if, however, a candidate's work falls within the natural sciences, a candidate should observe the limit described in the Department of Earth Sciences.

Applications for the limit of length of the thesis to be exceeded must be early — certainly no later than the time when the application for the appointment of examiners and the approval of the title of the thesis is made. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit of length will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed, without the prior permission of the Degree Committee, 60,000 words including tables, footnotes, bibliography and appendices. The Degree Committee points out that some of the best thesis extend to only half this length. Each page of statistical tables, charts or diagrams shall be regarded as equivalent to a page of text of the same size.

The thesis is not to exceed 80,000 words for the PhD and EdD degrees and 60,000 words for the MSc and MLitt degrees, in all cases excluding appendices, footnotes, reference list or bibliography. Only in the most exceptional circumstances will permission be given to exceed the stated limits. In such cases, you must make an application to the Degree Committee as early as possible -and no later than three months before it is proposed to submit the thesis, having regard to the dates of the Degree Committee meetings. Your application should (a) explain in detail the reasons why you are seeking the extension and (b) be accompanied by a full supporting statement from your supervisor showing that the extension is absolutely necessary in the interests of the total presentation of the subject.

For the PhD degree, not to exceed, without prior permission of the Degree Committee, 65,000 words, including appendices, footnotes, tables and equations not to contain more than 150 figures, but excluding the bibliography. A candidate must submit with their thesis a statement signed by the candidate themself giving the length of the thesis and the number of figures. Any thesis which, without the prior permission of the Degree Committee, exceeds the permitted limit will be referred back to the candidate before being forwarded to the examiners.

The thesis is not to exceed 80,000 words or go below 60,000 words for the PhD degree and not to exceed 60,000 words or go below 45,000 words for the MLitt degree, both including all notes and appendices but excluding the bibliography. A candidate must add to the preface of the thesis the following signed statement: 'The thesis does not exceed the regulation length, including footnotes, references and appendices but excluding the bibliography.'

In exceptional cases (when, for example, a candidate's thesis largely consists of an edition of a text) the Degree Committee may grant permission to exceed these limits but in such instances (a) a candidate must apply to exceed the length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be supported by a letter from a candidate's supervisor certifying that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement of the Degree Committee for the Faculty of English that thesis must conform to either the MHRA Style Book or the MLA Handbook for the Writers of Research papers, available from major bookshops. There is one proviso, however, to the use of these manuals: the Faculty does not normally recommend that students use the author/date form of citation and recommends that footnotes rather than endnotes be used. Bibliographies and references in thesis presented by candidates in ASNaC should conform with either of the above or to the practice specified in Cambridge Studies in Anglo-Saxon England.

Thesis presented by candidates in the Research Centre for English and Applied Linguistics must follow as closely as possible the printed style of the journal Applied Linguistics and referencing and spelling conventions should be consistent.

A signed declaration of the style-sheet used (and the edition, if relevant) must be made in the preliminary pages of the thesis.

PhD theses MUST NOT exceed 80,000 words, and will normally be near that length.

A minimum word length exists for PhD theses: 70,000 words (50,000 for MLitt theses)

The word limit includes appendices and the contents page but excludes the abstract, acknowledgments, footnotes, references, notes on transliteration, bibliography, abbreviations and glossary.  The Contents Page should be included in the word limit. Statistical tables should be counted as 150 words per table. Maps, illustrations and other pictorial images count as 0 words. Graphs, if they are the only representation of the data being presented, are to be counted as 150 words. However, if graphs are used as an illustration of statistical data that is also presented elsewhere within the thesis (as a table for instance), then the graphs count as 0 words.

Only under exceptional circumstances will permission be granted to exceed this limit. Applications for permission are made via CamSIS self-service pages. Applications must be made at least four months before the thesis is bound. Exceptions are granted when a compelling intellectual case is made.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, in all cases including footnotes and appendices but excluding bibliography. Permission to submit a thesis falling outside these limits, or to submit an appendix which does not count towards the word limit, must be obtained in advance from the Degree Committee.

The thesis is not to exceed 80,000 for the PhD degree and 60,000 words for the MSc or MLitt degree, both including footnotes, references and appendices but excluding bibliographies. One A4 page consisting largely of statistics, symbols or figures shall be regarded as the equivalent of 250 words. A candidate must add to the preface of their thesis the following signed statement: 'This thesis does not exceed the regulation length, including footnotes, references and appendices.'

For the PhD degree the thesis is not to exceed 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

For the PhD degree submission of a thesis between 55,000 and 80,000 words (exclusive of footnotes, appendices and bibliography) but subject to an overall word limit of 100,000 words (exclusive of bibliography, table of contents and any other preliminary matter). Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy. For the MLitt degree the thesis is not to exceed 60,000 words inclusive of footnotes but exclusive of bibliography, appendices, table of contents and any other preliminary matter. Figures, tables, images etc should be counted as the equivalent of 200 words for each A4 page, or part of an A4 page, that they occupy.

There is no standard format for the thesis in Mathematics.  Candidates should discuss the format appropriate to their topic with their supervisor.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, including footnotes and appendices but excluding the abstract, any acknowledgements, contents page(s), abbreviations, notes on transliteration, figures, tables and bibliography. Brief labels accompanying illustrations, figures and tables are also excluded from the word count. The Degree Committee point out that some very successful doctoral theses have been submitted which extend to no more than three-quarters of the maximum permitted length.

In linguistics, where examples are cited in a language other than Modern English, only the examples themselves will be taken into account for the purposes of the word limit. Any English translations and associated linguistic glosses will be excluded from the word count.

In theses written under the aegis of any of the language sections, all sources in the language(s) of the primary area(s) of research of the thesis will normally be in the original language. An English translation should be provided only where reading the original language is likely to fall outside the expertise of the examiners. Where such an English translation is given it will not be included in the word count. In fields where the normal practice is to quote in English in the main text, candidates should follow that practice. If the original text needs to be supplied, it should be placed in a footnote. These fields include, but are not limited to, general linguistics and film and screen studies.

Since appendices are included in the word limit, in some fields it may be necessary to apply to exceed the limit in order to include primary data or other materials which should be available to the examiners. Only under the most exceptional circumstances will permission be granted to exceed the limit in other cases. In all cases (a) a candidate must apply to exceed the prescribed maximum length at least three months before the date on which a candidate proposes to submit their thesis and (b) the application must be accompanied by a full supporting statement from the candidate's supervisor showing that such exemption from the prescribed limit of length is absolutely necessary.

It is a requirement within all language sections of MMLL, and also for Film, that dissertations must conform with the advice concerning abbreviations, quotations, footnotes, references etc published in the Style Book of the Modern Humanities Research Association (Notes for Authors and Editors). For linguistics, dissertations must conform with one of the widely accepted style formats in their field of research, for example the style format of the Journal of Linguistics (Linguistic Association of Great Britain), or of Language Linguistic Society of America) or the APA format (American Psychology Association). If in doubt, linguistics students should discuss this with their supervisor and the PhD Coordinator.

The thesis is not to exceed 80,000 words for the PhD degree and 60,000 words for the MLitt degree, both excluding notes, appendices, and bibliographies, musical transcriptions and examples, unless a candidate make a special case for greater length to the satisfaction of the Degree Committee. Candidates whose work is practice-based may include as part of the doctoral submission either a portfolio of substantial musical compositions, or one or more recordings of their own musical performance(s).

PhD (MLitt) theses in Philosophy must not be more than 80,000 (60,000) words, including appendices and footnotes but excluding bibliography.

Institute of Astronomy, Department of Materials Science & Metallurgy, Department of Physics:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, footnotes and appendices, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography and acknowledgements.

Department of Chemistry:

The thesis is not to exceed, without prior permission of the Degree Committee, 60,000 words, including summary/abstract, tables, and footnotes, but excluding table of contents, photographs, diagrams, figure captions, list of figures/diagrams, list of abbreviations/acronyms, bibliography, appendices and acknowledgements. Appendices are relevant to the material contained within the thesis but do not form part of the connected argument. Specifically, they may include derivations, code and spectra, as well as experimental information (compound name, structure, method of formation and data) for non-key molecules made during the PhD studies.

Applicable to the PhDs in Politics & International Studies, Latin American Studies, Multi-disciplinary Studies and Development Studies for all submissions from candidates admitted prior to and including October 2017.

A PhD thesis must not exceed 80,000 words, and will normally be near that length. The word limit includes appendices but excludes footnotes, references and bibliography. Footnotes should not exceed 20% of the thesis. Discursive footnotes are generally discouraged, and under no circumstances should footnotes be used to include material that would normally be in the main text, and thus to circumvent the word limits. Statistical tables should be counted as 150 words per table. Only under exceptional circumstances, and after prior application, will the Degree Committee allow a student to exceed these limits. A candidate must submit, with the thesis, a statement signed by her or himself attesting to the length of the thesis. Any thesis that exceeds the limit will be referred back to candidate for revision before being forwarded to the examiners.

Selecting Your Major Professor and Dissertation Committee

Your major professor and dissertation committee are essential partners in finishing your dissertation. Carefully select these individuals and nurture the academic relationship with them throughout your graduate career. 

Selecting a Major Professor

Committing to a lab, selecting a dissertation committee, meeting with your dissertation committee.

At the heart of faculty-graduate student collaboration and apprenticeship is the quality of the mentorship relationship. The major professor is responsible for guiding the student in the development of their dissertation project, and usually serves as Chair of the Thesis/Dissertation Committee. Before trying to define what kind of lab or research would work best for you, it can be helpful to start by assessing what your own style and needs are. The Council of Graduate Schools has a Quick Start Guide to assist in this process.

Student Perspective

Rotations go both ways. Ask yourself not only if you would be a good fit for the lab, but if the lab will be a good fit for you.

Write down your specific personal and professional needs. It is important to be brutally honest with yourself when doing this. How do you best learn and thrive in a laboratory setting?

• Mentorship style:
• Do you prefer more direct involvement with your Major Professor vs. postdocs and other grad students? How often do you want to meet directly with your Major Professor? Once a day, week, month, quarter?  Do you want to be the driver of your own project? Or do you want a Major Professor that is more willing to guide you through the nuances of your research? Does the Major Professor have specific requirements for graduation (E.g., a first author paper, multiple first-author papers, reviews, exit seminars, etc?)
• Opportunities:
• Research project - are you given a project or are you expected to come up with one on your own? Does the Major Professor have the appropriate network to help aid your future career growth? (E.g., industry? Academia? Something else?) Ask the Major Professor what lab alumni are doing now. Are they in academic institutions, biotech, industry, other professional settings?
• Mental Health:
• Consider how you might handle stressful situations or conflict. Does the Major Professor and lab environment seem appropriately supportive for you?  What kind of environment do you need to maintain your own mental health?  What do you need from your Major Professor when you’re struggling?  What is the Major Professor’s policy on vacation/sick leave/mental health days? 
• Communication:
• Offers insight into whether you met the Major Professor’s expectations.
• Does it seem like they took their time to fill out the assessment and give a fair honest evaluation?
• Ask the Major Professor how grad students are funded in the lab - direct grant support, fellowships, TA-ship If you are very committed to this lab and they do not have funding, ensure that you are willing to apply for grants and TA for financial support. Do not make the decision to fund yourself lightly, this will likely add at least a year onto your degree completion time.  

Faculty Perspective

It is important for students to know their own needs. One student may thrive in a particular lab environment, while others might struggle in the same situation.  For example, if you are completely new to the skill set necessary for the lab, then you may want to be certain that you will get the training necessary to do your job. Talk to current lab members about lab training culture and carefully think about this during rotations. 

• Make sure you have the opportunity to discuss the Major Professor and lab culture with students/postdocs in the lab and really LISTEN to what they have to say. Do you prefer hands-off mentors or hands-on mentors?  Ask the Major Professor about their mentoring style - how often they are in the lab and/or how often are they traveling? What will their availability/communication style be when they are not in the lab? Rotations are a perfect opportunity to get to know how the lab operates and how you feel in it.  Take any red flags seriously.  Even if you LOVE the research, if the lab environment and Major Professor are not a good fit for you, that lab is not the best choice in the long run. 
• Communication is Key:  If you are going through a situation that may impact your work it is important to communicate with your Major Professor. Reach out early with a plan that works for you; maybe you need a modified working schedule, or to move a deadline. Reaching out with a plan shows that you are being accountable.  Talking about mental health is not easy but remember that you don’t need to share details. You set the boundaries with which you are comfortable, communicate within those boundaries. You may want to reach out to your mentoring network to help you navigate these conversations. 

You must choose a lab to complete your studies by the beginning of the Spring Quarter in your first year. For doctoral students, the MCIP program will cease funding your stipend and a Major Professor must take over that financial obligation. Your rotations will hopefully give you an idea of which lab you would like to pursue your degree in.

There may be a circumstance in which you have an evaluation discussion with your rotation PI and they are more enthusiastic than you are about the prospect of joining their lab. This is a delicate situation that requires tact. If you are considering two different labs, be open and honest. Be polite and precisely detail the reasons behind your choice - you never know if you will end up working with the faculty member again in the future.

• Communicate often with the Major Professor during and after the rotation. Make it clear you're interested in joining the lab by saying so. Do not assume they know you're interested. Tell them how passionate you are about their research questions and how well you fit into their team, and ask them if they would consider being your ‘Major Professor’.
• Ask questions! In lab meetings, in one-on-ones with the major professor, and of other lab members.
• If you still have rotations to complete, inform the Major Professor about your plans. Ask them what their situation is for accepting a student, and the likelihood that they will still have a position available if you continue rotations.
• Do I want to spend the next 4-6 years closely working in this laboratory environment? Remember that the only constant will surely be the Major Professor. Other members will hopefully move on to new opportunities. 
• Do I truly enjoy the research?
• Talk to other members of the lab - how do they like working there? Focus on grad student perspectives as they have a unique position in the lab.
• Halfway through the rotation, request to meet with Major Professor to talk about your progress in the lab and areas that may need attention. These conversations are important to get a sense of how things are working and may help gauge the level of commitment and if you are ready to commit to the lab. If you are interested in joining the lab, let the Major Professor know before the end of the rotation so they have an opportunity to discuss feasibility.
• You can ask about funding by saying something like, “if you were to accept a graduate student into the lab right now, what are the expectations for funding? Would I be required to TA or find external funding, or are you in a position to support a new student at this time?” 
• Most Major Professors will be very transparent about the current situation and expectations.  Just keep in mind that things can always change - a well-funded lab may not be so well-funded in a few years, and vice versa.  That is why you should always be applying for fellowships, even if you join a very well-funded lab.  Ask your Major Professor early about what fellowships they would like you to apply for and when.

Your dissertation will be a culmination of your research and is often a chance to show you are an expert in your given subject matter. A dissertation committee is formed after your qualifying exam and is crucial to help direct your research and guide the preparation of the dissertation. This committee is chaired by your Major Professor and includes at least 2 other faculty members. You will want to compose your dissertation committee in consultation with your Major Professor. MCIP degree requirements state that the majority of your dissertation committee should be MCIP members, so at least two out of three. 

• Criteria to create a short-list

Relation to your field of study - you want mentors who are knowledgeable about the area of research and/or techniques used

Involvement in other programs/committees - ensure the faculty is not overcommitted. This can make scheduling hard or limit the interactions

Collaborators or competitors -  look for attributes complimentary to your other mentors, and avoid conflicts that can prolong or inhibit completion of your degree

Networking - faculty with a strong network and/or reputation who might help you with future career opportunities

Who values you - Is it obvious that the professor wants you to do well? Think about your experiences with the professor, whether they taught during your courses or you run into them in the hallway. This can hint at the types of interactions you can expect, the ability to have conversations or how they will offer constructive criticism

• Narrowing down the list

Consult with your major professor – This may help to narrow down your list and provide additional names to consider

Ask more senior students - Are there students who are close to graduating that have your prospective member on their dissertation committee? Ask other students how the prospective faculty member was during a qualifying exam. 

Meet with the professor before committing to have them in your dissertation committee - This is a great way to see if you get along with them outside of the classroom and a way to build a relationship. 

It is common to interact with your committee members throughout your post-qualifying exam years both formally and informally. You should seek out and lean on your Dissertation Committee to assess your progress and also assess the feasibility of your research, and whether to narrow or widen its scope, towards the completion of your degree.

Once you have selected your Dissertation Committee, plan to have an initial meeting with the committee and at least one meeting per year every year until graduation.

• Initial meeting
• The purpose of the Initial Meeting is to acquaint your committee with your project, your data and progress so far, your plans for the rest of the project/dissertation, and any problems you anticipate or alternatives you have in mind. This is also an opportunity for your committee to have input on your project and/or methods to help shape your proposed body of work.  Shaping and refining the scope of your dissertation should hopefully be a collaborative effort between you, your Major Professor, and your committee.
• Annual Meeting
• The purpose of the Annual Meetings is to update your committee on your progress since your last meeting, inform them of any delays or problems you have encountered or changes to the project that have been made, and to seek advice and input on any outstanding issues. Your annual meetings should also end with an outline of what work remains and what your proposed timeline for completion is. These annual meetings will help to avoid any ‘unexpected surprises’ for your committee if you have significantly changed the overall direction or scope of your work (which may happen). Your committee should be well aware of any and all changes before reading your dissertation!  In some cases, your committee can also advocate on your behalf, especially in situations where certain experiments are not working, or part of the project ended up being significantly more work than initially anticipated. In these instances, your committee can often help to reach consensus on what remaining work is ( or is not ) required to complete your dissertation.
