How to Structure a Dissertation – A Step by Step Guide

Published by Owen Ingram at August 11th, 2021 , Revised On September 20, 2023

A dissertation – sometimes called a thesis –  is a long piece of information backed up by extensive research. This one, huge piece of research is what matters the most when students – undergraduates and postgraduates – are in their final year of study.

On the other hand, some institutions, especially in the case of undergraduate students, may or may not require students to write a dissertation. Courses are offered instead. This generally depends on the requirements of that particular institution.

If you are unsure about how to structure your dissertation or thesis, this article will offer you some guidelines to work out what the most important segments of a dissertation paper are and how you should organise them. Why is structure so important in research, anyway?

One way to answer that, as Abbie Hoffman aptly put it, is because: “Structure is more important than content in the transmission of information.”

Also Read:   How to write a dissertation – step by step guide .

How to Structure a Dissertation or Thesis

It should be noted that the exact structure of your dissertation will depend on several factors, such as:

  • Your research approach (qualitative/quantitative)
  • The nature of your research design (exploratory/descriptive etc.)
  • The requirements set for forth by your academic institution.
  • The discipline or field your study belongs to. For instance, if you are a humanities student, you will need to develop your dissertation on the same pattern as any long essay .

This will include developing an overall argument to support the thesis statement and organizing chapters around theories or questions. The dissertation will be structured such that it starts with an introduction , develops on the main idea in its main body paragraphs and is then summarised in conclusion .

However, if you are basing your dissertation on primary or empirical research, you will be required to include each of the below components. In most cases of dissertation writing, each of these elements will have to be written as a separate chapter.

But depending on the word count you are provided with and academic subject, you may choose to combine some of these elements.

For example, sciences and engineering students often present results and discussions together in one chapter rather than two different chapters.

If you have any doubts about structuring your dissertation or thesis, it would be a good idea to consult with your academic supervisor and check your department’s requirements.

Parts of  a Dissertation or Thesis

Your dissertation will  start with a t itle page that will contain details of the author/researcher, research topic, degree program (the paper is to be submitted for), and research supervisor. In other words, a title page is the opening page containing all the names and title related to your research.

The name of your university, logo, student ID and submission date can also be presented on the title page. Many academic programs have stringent rules for formatting the dissertation title page.


The acknowledgments section allows you to thank those who helped you with your dissertation project. You might want to mention the names of your academic supervisor, family members, friends, God, and participants of your study whose contribution and support enabled you to complete your work.

However, the acknowledgments section is usually optional.

Tip: Many students wrongly assume that they need to thank everyone…even those who had little to no contributions towards the dissertation. This is not the case. You only need to thank those who were directly involved in the research process, such as your participants/volunteers, supervisor(s) etc.

Perhaps the smallest yet important part of a thesis, an abstract contains 5 parts:

  • A brief introduction of your research topic.
  • The significance of your research.
  •  A line or two about the methodology that was used.
  • The results and what they mean (briefly); their interpretation(s).
  • And lastly, a conclusive comment regarding the results’ interpretation(s) as conclusion .

“ Our expert dissertation writers can help you with all stages of the dissertation writing process including topic research and selection, dissertation plan, dissertation proposal , methodology , statistical analysis , primary and secondary research, findings and analysis and complete dissertation writing. “

Tip: Make sure to highlight key points to help readers figure out the scope and findings of your research study without having to read the entire dissertation. The abstract is your first chance to impress your readers. So, make sure to get it right. Here are detailed guidelines on how to write abstract for dissertation .

Table of Contents

Table of contents is the section of a dissertation that guides each section of the dissertation paper’s contents. Depending on the level of detail in a table of contents, the most useful headings are listed to provide the reader the page number on which said information may be found at.

Table of contents can be inserted automatically as well as manually using the Microsoft Word Table of Contents feature.

List of Figures and Tables

If your dissertation paper uses several illustrations, tables and figures, you might want to present them in a numbered list in a separate section . Again, this list of tables and figures can be auto-created and auto inserted using the Microsoft Word built-in feature.

List of Abbreviations

Dissertations that include several abbreviations can also have an independent and separate alphabetised  list of abbreviations so readers can easily figure out their meanings.

If you think you have used terms and phrases in your dissertation that readers might not be familiar with, you can create a  glossary  that lists important phrases and terms with their meanings explained.

quantitative dissertation help


Introduction chapter  briefly introduces the purpose and relevance of your research topic.

Here, you will be expected to list the aim and key objectives of your research so your readers can easily understand what the following chapters of the dissertation will cover. A good dissertation introduction section incorporates the following information:

  • It provides background information to give context to your research.
  • It clearly specifies the research problem you wish to address with your research. When creating research questions , it is important to make sure your research’s focus and scope are neither too broad nor too narrow.
  • it demonstrates how your research is relevant and how it would contribute to the existing knowledge.
  • It provides an overview of the structure of your dissertation. The last section of an introduction contains an outline of the following chapters. It could start off with something like: “In the following chapter, past literature has been reviewed and critiqued. The proceeding section lays down major research findings…”
  • Theoretical framework – under a separate sub-heading – is also provided within the introductory chapter. Theoretical framework deals with the basic, underlying theory or theories that the research revolves around.

All the information presented under this section should be relevant, clear, and engaging. The readers should be able to figure out the what, why, when, and how of your study once they have read the introduction. Here are comprehensive guidelines on how to structure the introduction to the dissertation .

“Overwhelmed by tight deadlines and tons of assignments to write? There is no need to panic! Our expert academics can help you with every aspect of your dissertation – from topic creation and research problem identification to choosing the methodological approach and data analysis.”

Literature Review 

The  literature review chapter  presents previous research performed on the topic and improves your understanding of the existing literature on your chosen topic. This is usually organised to complement your  primary research  work completed at a later stage.

Make sure that your chosen academic sources are authentic and up-to-date. The literature review chapter must be comprehensive and address the aims and objectives as defined in the introduction chapter. Here is what your literature research chapter should aim to achieve:

  • Data collection from authentic and relevant academic sources such as books, journal articles and research papers.
  • Analytical assessment of the information collected from those sources; this would involve a critiquing the reviewed researches that is, what their strengths/weaknesses are, why the research method they employed is better than others, importance of their findings, etc.
  • Identifying key research gaps, conflicts, patterns, and theories to get your point across to the reader effectively.

While your literature review should summarise previous literature, it is equally important to make sure that you develop a comprehensible argument or structure to justify your research topic. It would help if you considered keeping the following questions in mind when writing the literature review:

  • How does your research work fill a certain gap in exiting literature?
  • Did you adopt/adapt a new research approach to investigate the topic?
  • Does your research solve an unresolved problem?
  • Is your research dealing with some groundbreaking topic or theory that others might have overlooked?
  • Is your research taking forward an existing theoretical discussion?
  • Does your research strengthen and build on current knowledge within your area of study? This is otherwise known as ‘adding to the existing body of knowledge’ in academic circles.

Tip: You might want to establish relationships between variables/concepts to provide descriptive answers to some or all of your research questions. For instance, in case of quantitative research, you might hypothesise that variable A is positively co-related to variable B that is, one increases and so does the other one.

Research Methodology

The methods and techniques ( secondary and/or primar y) employed to collect research data are discussed in detail in the  Methodology chapter. The most commonly used primary data collection methods are:

  • questionnaires
  • focus groups
  • observations

Essentially, the methodology chapter allows the researcher to explain how he/she achieved the findings, why they are reliable and how they helped him/her test the research hypotheses or address the research problem.

You might want to consider the following when writing methodology for the dissertation:

  • Type of research and approach your work is based on. Some of the most widely used types of research include experimental, quantitative and qualitative methodologies.
  • Data collection techniques that were employed such as questionnaires, surveys, focus groups, observations etc.
  • Details of how, when, where, and what of the research that was conducted.
  • Data analysis strategies employed (for instance, regression analysis).
  • Software and tools used for data analysis (Excel, STATA, SPSS, lab equipment, etc.).
  • Research limitations to highlight any hurdles you had to overcome when carrying our research. Limitations might or might not be mentioned within research methodology. Some institutions’ guidelines dictate they be mentioned under a separate section alongside recommendations.
  • Justification of your selection of research approach and research methodology.

Here is a comprehensive article on  how to structure a dissertation methodology .

Research Findings

In this section, you present your research findings. The dissertation findings chapter  is built around the research questions, as outlined in the introduction chapter. Report findings that are directly relevant to your research questions.

Any information that is not directly relevant to research questions or hypotheses but could be useful for the readers can be placed under the  Appendices .

As indicated above, you can either develop a  standalone chapter  to present your findings or combine them with the discussion chapter. This choice depends on  the type of research involved and the academic subject, as well as what your institution’s academic guidelines dictate.

For example, it is common to have both findings and discussion grouped under the same section, particularly if the dissertation is based on qualitative research data.

On the other hand, dissertations that use quantitative or experimental data should present findings and analysis/discussion in two separate chapters. Here are some sample dissertations to help you figure out the best structure for your own project.

Sample Dissertation

Tip: Try to present as many charts, graphs, illustrations and tables in the findings chapter to improve your data presentation. Provide their qualitative interpretations alongside, too. Refrain from explaining the information that is already evident from figures and tables.

The findings are followed by the  Discussion chapter , which is considered the heart of any dissertation paper. The discussion section is an opportunity for you to tie the knots together to address the research questions and present arguments, models and key themes.

This chapter can make or break your research.

The discussion chapter does not require any new data or information because it is more about the interpretation(s) of the data you have already collected and presented. Here are some questions for you to think over when writing the discussion chapter:

  • Did your work answer all the research questions or tested the hypothesis?
  • Did you come up with some unexpected results for which you have to provide an additional explanation or justification?
  • Are there any limitations that could have influenced your research findings?

Here is an article on how to  structure a dissertation discussion .

Conclusions corresponding to each research objective are provided in the  Conclusion section . This is usually done by revisiting the research questions to finally close the dissertation. Some institutions may specifically ask for recommendations to evaluate your critical thinking.

By the end, the readers should have a clear apprehension of your fundamental case with a focus on  what methods of research were employed  and what you achieved from this research.

Quick Question: Does the conclusion chapter reflect on the contributions your research work will make to existing knowledge?

Answer: Yes, the conclusion chapter of the research paper typically includes a reflection on the research’s contributions to existing knowledge.  In the “conclusion chapter”, you have to summarise the key findings and discuss how they add value to the existing literature on the current topic.

Reference list

All academic sources that you collected information from should be cited in-text and also presented in a  reference list (or a bibliography in case you include references that you read for the research but didn’t end up citing in the text), so the readers can easily locate the source of information when/if needed.

At most UK universities, Harvard referencing is the recommended style of referencing. It has strict and specific requirements on how to format a reference resource. Other common styles of referencing include MLA, APA, Footnotes, etc.

Each chapter of the dissertation should have relevant information. Any information that is not directly relevant to your research topic but your readers might be interested in (interview transcripts etc.) should be moved under the Appendices section .

Things like questionnaires, survey items or readings that were used in the study’s experiment are mostly included under appendices.

FAQs About Structure a Dissertation

What does the title page of a dissertation contain.

The title page will contain details of the author/researcher, research topic , degree program (the paper is to be submitted for) and research supervisor’s name(s). The name of your university, logo, student number and submission date can also be presented on the title page.

What is the purpose of adding acknowledgement?

The acknowledgements section allows you to thank those who helped you with your dissertation project. You might want to mention the names of your academic supervisor, family members, friends, God and participants of your study whose contribution and support enabled you to complete your work.

Can I omit the glossary from the dissertation?

Yes, but only if you think that your paper does not contain any terms or phrases that the reader might not understand. If you think you have used them in the paper,  you must create a glossary that lists important phrases and terms with their meanings explained.

What is the purpose of appendices in a dissertation?

Any information that is not directly relevant to research questions or hypotheses but could be useful for the readers can be placed under the Appendices, such as questionnaire that was used in the study.

Which referencing style should I use in my dissertation?

You can use any of the referencing styles such as APA, MLA, and Harvard, according to the recommendation of your university; however, almost all UK institutions prefer Harvard referencing style .

What is the difference between references and bibliography?

References contain all the works that you read up and used and therefore, cited within the text of your thesis. However, in case you read on some works and resources that you didn’t end up citing in-text, they will be referenced in what is called a bibliography.

Additional readings might also be present alongside each bibliography entry for readers.

  • Dissertation Structure & Layout Explained + Examples

How do you write a dissertation chapter structure? Which chapter comes first and which one comes last? What do you write in your dissertation chapters and how do you write them? In this article, you will be getting the answers to all of these questions so keep reading.

Dissertation Chapters Outline

  • Chapter One: Introduction

The dissertation chapter 1 outline basically comprises a hook, a background, the research aims/questions and the topic. In your dissertation chapter 1, the first thing you should write is the hook. The hook is what will determine whether the reader will be interested in further reading or get bored or confused with your dissertation. So, try to make your hook as interesting, controversial, or bold as possible.

After your hook, the next thing to do is write the background for your topic. This will let the reader relate to your topic as they can now understand what events led to it.

Next, state your research aims or questions. It is always best to break these into a list of numbered items.

Finally, introduce your topic and the other chapters. You may also choose to introduce your topic in the middle of the introduction or at the end of your dissertation chapter 1 example.

Note: Your reader must be able to fully understand the intent of your dissertation just by reading your introduction. What many students do not know is that the introduction, the methodology and the analysis chapters get the most points. So, you have to write them well.

  • Chapter Two: Review of Literature

In this chapter, you will discuss your sources and show how their information is relevant to your topic. The dissertation chapter 2 outline consists of showing the relevance of other literature to your research work, why you chose them, how your dissertation differs from them, and your theoretical framework.

In your dissertation chapter 2, you should also critique this literature and point out the research gaps in them.

Now it is important to mention that you should only cite academic materials in your literature review and your entire dissertation. Citing sources from random blogs or websites may cost you some marks. Also, you do not have to limit your sources to written texts, you can use videos but do not forget to cite according to your school’s reference system.

  • Chapter Three: Methodology

After writing your chapter two, the next chapter to write is your methodology chapter in your dissertation chapters structure. Here, you will explain your research design, the tools you use, and why you chose them. You will also mention if you encountered any challenges in the course of your research and what you did about them. Finally, you will write your ethical considerations. The ethical considerations usually entail proof that you did not force participants (if any) without their consent to fill questionnaires or partake in interviews. Also, you will mention if you employed the help of other researchers during your research.

Here, in your methodology chapter, you may need to use graphs, charts, tables, or any relevant image to give a visual representation of what you are explaining. Lastly, you will also tell if there is any new data or information you added to your research (that was not in your research proposal) and why you added them. Similarly, if you removed any data or information, you should state so in this chapter.

Now for some students, your methodology chapter may be as few as 1000 words while for some others, it may be as much as 3000 words. This depends on how much you have to write.

  • Chapter Four: Analysis

In this chapter, you will present the data you have gotten during your research. You will carefully analyze each one of them from relevant to irrelevant. You will also point out any flaws or perfection in the data you have written. Your analysis chapter has to be well-written, detailed, and easy to understand as it is this chapter that most markers usually award the most points.

It is also in this chapter that you may use the most word count. You may also use the most word count in your results and discussion chapter. However, this is not always the case.

  • Chapter Five: Results and Discussion

In this chapter, you present the results of your analysis and you discuss them. For some students, the results and discussion chapter may be merged with the analysis chapter to become one. In this chapter, you will discuss in detail the results you got from analyzing all the data you discovered. You will also point out research gaps, flaws, or perfection in your results. Make sure your interpretation of your analysis is broken down in a manner that your reader can understand.

  • Chapter Six: Conclusion

Lastly, write the conclusion of your dissertation. Your conclusion is almost like writing your introduction. However, you will show what you have done rather than what you will do. That means you may use more past tense. Here, you will start from the beginning of what your dissertation aimed to do. Next, you will summarize the literature review, your methodology, and your analysis chapters. You will also make recommendations to future researchers that may use your research work for reference.

Writing a dissertation chapter outline does not have to be confusing or terrifying to you. Simply follow the steps and instructions in this article and you will find it easier to write.

Low-cost Techniques to Measure and Predict Air Pollution Exposure

 Exposure to air pollution is the fifth leading cause of death worldwide. This risk is dominated by exposure to fine particulate matter (PM 2.5 ) and is deemed even more critical in low- and middle-income countries due to a lack of data available to build effective policies. The scarcity of actionable air quality data in these regions is due to thehigh cost of research-grade air pollutant monitors. The core objectives of my thesis are to (1) develop a low-cost method to measure atmospheric black carbon, a major contributor to PM 2.5 in developing nations, at existing PM 2.5 monitoring sites, (2) use the method to measure the BC component of PM2.5 to identify leading combustion sources contributing to pollutant concentrations in African cities, and (3) develop a framework for developing a robust deep learning-based generalized model to predict PM 2.5 pollutant concentrations that is transferable to other locations. 

US Department of State collects air pollutant data at selected US embassies and consulates around the world to inform embassy personnel and citizens about the local air quality. These measurements are made by Beta Attenuation Monitors (BAMs) to measure hourly ambient PM 2.5 concentrations. These BAMs at the embassies collect PM 2.5 onto glass-fiber filter tapes at a circular spot with a fixed flow rate of 1m 3 /h -1 for approximately an hour and pass beta ray through the particle deposit. Hourly PM 2.5 concentration is calculated with Beer-Lambert law by utilizing the attenuation of beta rays through the spot. The BAM moves the spot to sample on a clean area of the filter tape and continues this process until the tape is exhausted. A new tape is installed and the used tapes are usually discarded after a brief period of storage. Chapter 3 of this thesis investigates a cost-effective method to leverage used tapes from these existing BAMs to measure ambient black carbon concentration at an hourly resolution. We developed an image reflectance-based method to determine hourly black carbon (BC) concentrations from red light reflectance using cell phone cameras. The method relies on the working principle that the BC loading on a filter sample is correlated to intensity of reflected red light from the sample. The hourly effective detection limit of the method is estimated to be around 0.15 μg/m - 3 of BC, which makes it suitable to use in most micro-environments, especially the ones with high combustion emissions. This method only requires a reference card sheet and a cellphone camera. Both of these items are easily accessible making this method practically a "zero" cost measurement technique. 

We used this method to measure hourly BC concentrations at multiple locations in Africa and compared it to our measurements in Pittsburgh. Unregulated emission sources are one of the major factors for the high pollution levels in developing nations. For example, primary sources of air pollution in Africa are unregulated transport emissions, burning of solid fuels for cooking and heating in winter seasons, open burning of crop residues and burning fossil fuel for electricity production. Air quality measurements can provide evidence on these high emitting sources for effective policymaking, further alleviating the air pollution scenario in these regions. Chapter 4 presents measurements on BC component of hourly PM 2.5 data with our image reflectance-based method applied on used BAM tapes from multiple cities in Africa, which will be used in investigating and identifying primary sources of pollutants at these locations. The cities in this study include Abidjan (Côte d’Ivoire), Accra (Ghana) and Addis Ababa (Ethiopia). The measurements show a significantly high BC levels across the cities and seasons in Africa. Availability of hourly BC information, in addition to PM 2.5 measurements, reveal high contribution of combustion emissions in the local air pollution. In Addis Ababa, BC composed 20% of PM 2.5 both in summer and winter seasons at two locations within the city. BC measurements in Abidjan showed a higher BC level during wet season due to increased burning of solid fuels to heat the houses as this period experiences lower temperatures. Hourly data also allowed us to derive diurnal patterns of BC for all cities. Accra showed a unique peak at 2 am in the night. This peak was later identified to be from diesel generators used by US embassy at Accra to meet their power demands during power outage incidents and/or illicit waste burning at night. Thus, our measurements reveal tons of information on pollutant levels as well as emission sources. 

A step further in informed policymaking for reducing exposure during hazardous levels of air pollution is to develop a forecast model that can predict air pollutant levels with the use of temporally dynamic variables. A major benefit of these forecast models is their ability to predict high pollution episodes so that both precautionary and preventive measure can be taken in advance to alleviate the exposure levels. Precautionary measures include wearing masks or staying home in case of severe pollution episodes, whereas preventive measures encompass coordinating with local industries and commercial plants to dampen their activities to reduce their emissions. 

Studies have developed variants of land-use regression-based models to forecast air pollution, but these models show poor prediction capabilities and their performance saturate despite inclusion of myriad features for training models. Most of the high pollution episodes overlap with period of temperature inversions, which is period of a very low planetary boundary layer height with minimal atmospheric circulation trapping air pollutants close to the ground. Therefore, we built models that use boundary layer height and related meteorological parameters among training features. Chapter 5 investigates deep learning models to build a novel neural network-based forecast model that utilizes training covariates, including air pollutant and weather-based parameters forecast from GEOS-CF model to generate a more robust and generalized empirical prediction model to forecast PM 2.5 a day in advance. We use 5 years of low-cost sensor-based PM 2.5 data as the ground truth in training the models to predict PM 2.5 for locations in Monongahela Valley, Pennsylvania.

How to Write a Dissertation or Thesis Proposal

Published on September 21, 2022 by Tegan George . Revised on July 18, 2023.

When starting your thesis or dissertation process, one of the first requirements is a research proposal or a prospectus. It describes what or who you want to examine, delving into why, when, where, and how you will do so, stemming from your research question and a relevant topic .

The proposal or prospectus stage is crucial for the development of your research. It helps you choose a type of research to pursue, as well as whether to pursue qualitative or quantitative methods and what your research design will look like.

What should your proposal contain, dissertation question examples, what should your proposal look like, dissertation prospectus examples, other interesting articles, frequently asked questions about proposals.

Prior to jumping into the research for your thesis or dissertation, you first need to develop your research proposal and have it approved by your supervisor. It should outline all of the decisions you have taken about your project, from your dissertation topic to your hypotheses and research objectives .

Depending on your department’s requirements, there may be a defense component involved, where you present your research plan in prospectus format to your committee for their approval.

Your proposal should answer the following questions:

  • Why is your research necessary?
  • What is already known about your topic?
  • Where and when will your research be conducted?
  • Who should be studied?
  • How can the research best be done?

Ultimately, your proposal should persuade your supervisor or committee that your proposed project is worth pursuing.

Prevent plagiarism. Run a free check.

Strong research kicks off with a solid research question , and dissertations are no exception to this.

Dissertation research questions should be:

  • Focused on a single problem or issue
  • Researchable using primary and/or secondary sources
  • Feasible to answer within the timeframe and practical constraints
  • Specific enough to answer thoroughly
  • Complex enough to develop the answer over the space of a paper or thesis
  • Relevant to your field of study and/or society more broadly
  • What are the main factors enticing people under 30 in suburban areas to engage in the gig economy?
  • Which techniques prove most effective for 1st-grade teachers at local elementary schools in engaging students with special needs?
  • Which communication streams are the most effective for getting those aged 18-30 to the polls on Election Day?

An easy rule of thumb is that your proposal will usually resemble a (much) shorter version of your thesis or dissertation. While of course it won’t include the results section , discussion section , or conclusion , it serves as a “mini” version or roadmap for what you eventually seek to write.

Be sure to include:

  • A succinct introduction to your topic and problem statement
  • A brief literature review situating your topic within existing research
  • A basic outline of the research methods you think will best answer your research question
  • The perceived implications for future research
  • A reference list in the citation style of your choice

The length of your proposal varies quite a bit depending on your discipline and type of work you’re conducting. While a thesis proposal is often only 3-7 pages long, a prospectus for your dissertation is usually much longer, with more detailed analysis. Dissertation proposals can be up to 25-30 pages in length.

Writing a proposal or prospectus can be a challenge, but we’ve compiled some examples for you to get your started.

The research methods you use depend on the type of data you need to answer your research question .

  • If you want to measure something or test a hypothesis , use quantitative methods . If you want to explore ideas, thoughts and meanings, use qualitative methods .
  • If you want to analyze a large amount of readily-available data, use secondary data. If you want data specific to your purposes with control over how it is generated, collect primary data.
  • If you want to establish cause-and-effect relationships between variables , use experimental methods. If you want to understand the characteristics of a research subject, use descriptive methods.

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.)

A well-planned research design helps ensure that your methods match your research aims, that you collect high-quality data, and that you use the right kind of analysis to answer your questions, utilizing credible sources . This allows you to draw valid , trustworthy conclusions.

The priorities of a research design can vary depending on the field, but you usually have to specify:

  • Your research questions and/or hypotheses
  • Your overall approach (e.g., qualitative or quantitative )
  • The type of design you’re using (e.g., a survey , experiment , or case study )
  • Your sampling methods or criteria for selecting subjects
  • Your data collection methods (e.g., questionnaires , observations)
  • Your data collection procedures (e.g., operationalization , timing and data management)
  • Your data analysis methods (e.g., statistical tests  or thematic analysis )

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.

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

  • Researchability
  • Feasibility and specificity
  • Relevance and originality

Quantum Probes for Far-field thermal Sensing and Imaging

Quantum-enhanced approaches enable high-resolution imaging and sensing with signal-to-noise ratios beyond classical limits. However, operating in the quantum regime is highly susceptible to environmental influences and experimental conditions. Implementing these techniques necessitates highly controlled environments or intricate preparation methods, which can restrict their practical applications. This thesis explores the practical applications of quantum sensing, focusing on thermal sensing with bright quantum sources in biological and electronic contexts. Additionally, I discuss the development of a multimode source for quantum imaging applications and an on-chip atomic interface for scalable light-atom interactions. I built all the experimental setups from the beginning; a microscope setup for nanodiamond-based thermal sensing inside living cells, a four-wave mixing setup using a Rb cell for thermal imaging of microelectronics and multimode source, and a vacuum chamber for on-chip atomic interface.

Quantum sensing can be realized using atomic spins or optical photons possessing quantum information. Among these, color centers inside diamonds stand out as robust quantum spin defects (effective atomic spins), maintaining their quantum properties even in ambient conditions. In this thesis, I studied the role of an ensemble of color centers inside nanodiamonds as a probe of temperature in a living cell. Our approach involves incubating nanodiamonds in endothelial culture cells to achieve sub-kelvin sensitivity in temperature measurement. The results reveal a temperature error of 0.38 K and a sensitivity of 3.46 K/sqrt(Hz) after 83 seconds of measurement. Furthermore, I discuss the constraints of nanodiamond temperature sensing in living cells, propose strategies to surmount these limitations, and explore potential applications arising from such measurements.

Another ubiquitous quantum probe is light with quantum properties. Photons, the particles of light, can carry quantum correlations and have minimal interactions with each other and, to some extent, the environment. This capability theoretically allows for quantum-enhanced imaging or sensing of sample’s properties. In this thesis, I report on the demonstration of quantum-enhanced temperature sensing in microelectronics using bright quantum optical signals. I discuss the first demonstration of quantum thermal imaging used to identify hot spots and analyze heat transport in electronic systems.

To achieve this, we employed lock-in detection of thermoreflectivity, enabling us to measure temperature changes in a micro-wire induced by an electric current with an accuracy better than 0.04 degrees, averaged over 0.1 seconds. Our results demonstrate a nearly 50 % improvement in accuracy compared to using classical light at the same power, marking the first demonstration of below-shot-noise thermoreflectivity sensing. We applied this imaging technique to both aluminum and niobium-based circuits, achieving a thermal resolution of 42 mK during imaging. We scanned a 48 × 48 μm area with 3-4 dB squeezing compared to classical measurements. Based on these results, we infer possibility of generating a 256×256 pixel image with a temperature sensitivity of 42 mK within 10 minutes. This quantum thermoreflective imaging technique offers a more accurate method for detecting electronic hot spots and assessing heat distribution, and it may provide insights into the fundamental properties of electronic materials and superconductors.

In transitioning from single-mode to multimode quantum imaging, I conducted further research on techniques aimed at generating multimode quantum light. This involved an in-depth analysis of the correlation characteristics essential for utilizing quantum light sources in imaging applications. To achieve the desired multimode correlation regime, I developed a system centered on warm Rubidium vapor with nonlinear gain and feedback processes. The dynamics of optical nonlinearity in the presence of gain and feedback can lead to complexity, even chaos, in certain scenarios. Instabilities in temporal, spectral, spatial, or polarization aspects of optical fields may arise from chaotic responses within an optical x (2) or x (3) nonlinear medium positioned between two cavity mirrors or preceding a single feedback mirror. However, the complex mode dynamics, high-order correlations, and transitions to instability in such systems remain insufficiently understood.

In this study, we focused on a x (3) medium featuring an amplified four-wave mixing process, investigating noise and correlations among multiple optical modes. While individual modes displayed intensity fluctuations, we observed a reduction in relative intensity noise approaching the standard quantum limit, constrained by the camera speed. Remarkably, we recorded a relative noise reduction exceeding 20 dB and detected fourth-order intensity correlations among four spatial modes. Moreover, this process demonstrated the capability to generate over 100 distinct correlated quadruple modes.

In addition to conducting multimode analysis to develop a scalable imaging system, I have explored methodologies aimed at miniaturizing light-atom interactions on a chip for the scalable generation of quantum correlations. While warm atomic vapors have been utilized for generating or storing quantum correlations, they are plagued by challenges such as inhomogeneous broadening and low coherence time. Enhancing control over the velocity, location, and density of atomic gases could significantly improve light-atom interaction. Although laser cooling is a common technique for cooling and trapping atoms in a vacuum, its implementation in large-scale systems poses substantial challenges. As an alternative, I focused on developing an on-chip system integrated with atomic vapor controlled by surface acoustic waves (SAWs).

Surface acoustic waves are induced by an RF signal along the surface of a piezoelectric material and have already been proven to be effective for manipulating particles within microfluidic channels. Expanding upon this concept, I investigated the feasibility of employing a similar approach to manipulate atoms near the surface of a photonic circuit. The interaction between SAWs and warm atomic vapor is expected as a mechanism for controlling atomic gases in proximity to photonic chips for quantum applications. Through theoretical analysis spanning molecular dynamics and fluid dynamics regimes, I identified the experimental conditions necessary to observe acoustic wave behavior in atomic vapor. To validate this theory, I constructed an experiment comprising a vacuum chamber housing Rb atoms and a lithium niobate chip featuring interdigital transducers for launching SAWs. However, preliminary experimental results yielded no significant signals from SAW-atom interactions. Subsequent analysis revealed that observing such interactions requires sensitivity and signal-to-noise ratio (SNR) beyond the capabilities of the current setup. Multiple modifications, including increasing buffer gas pressure and mitigating RF cross-talk, are essential for conclusively observing and controlling these interactions.
