Proposal Overview and Format

Proposal committee, proposal hearing or meeting.

• Printing Credit for Use in School of Education Labs

Students are urged to begin thinking about a dissertation topic early in their degree program. Concentrated work on a dissertation proposal normally begins after successful completion of the Second-Year Review, which often includes a “mini” proposal, an extended literature review, or a theoretical essay, plus advancement to doctoral candidacy. In defining a dissertation topic, the student collaborates with their faculty advisor or dissertation advisor (if one is selected) in the choice of a topic for the dissertation.

The dissertation proposal is a comprehensive statement on the extent and nature of the student’s dissertation research interests. Students submit a draft of the proposal to their dissertation advisor between the end of the seventh and middle of the ninth quarters. The student must provide a written copy of the proposal to the faculty committee no later than two weeks prior to the date of the proposal hearing. Committee members could require an earlier deadline (e.g., four weeks before the hearing).

The major components of the proposal are as follows, with some variations across Areas and disciplines:

• A detailed statement of the problem that is to be studied and the context within which it is to be seen. This should include a justification of the importance of the problem on both theoretical and educational grounds.
• A thorough review of the literature pertinent to the research problem. This review should provide proof that the relevant literature in the field has been thoroughly researched. Good research is cumulative; it builds on the thoughts, findings, and mistakes of others.
• its general explanatory interest
• the overall theoretical framework within which this interest is to be pursued
• the model or hypotheses to be tested or the research questions to be answered
• a discussion of the conceptual and operational properties of the variables
• an overview of strategies for collecting appropriate evidence (sampling, instrumentation, data collection, data reduction, data analysis)
• a discussion of how the evidence is to be interpreted (This aspect of the proposal will be somewhat different in fields such as history and philosophy of education.)
• If applicable, students should complete a request for approval of research with human subjects, using the Human Subjects Review Form ( http://humansubjects.stanford.edu/ ). Except for pilot work, the University requires the approval of the Administrative Panel on Human Subjects in Behavioral Science Research before any data can be collected from human subjects.

Registration (i.e., enrollment) is required for any quarter during which a degree requirement is completed, including the dissertation proposal. Refer to the Registration or Enrollment for Milestone Completion section for more details.

As students progress through the program, their interests may change. There is no commitment on the part of the student’s advisor to automatically serve as the dissertation chair. Based on the student’s interests and the dissertation topic, many students approach other GSE professors to serve as the dissertation advisor, if appropriate.

A dissertation proposal committee is comprised of three academic council faculty members, one of whom will serve as the major dissertation advisor. Whether or not the student’s general program advisor serves on the dissertation proposal committee and later the reading committee will depend on the relevance of that faculty member’s expertise to the topic of the dissertation, and their availability. There is no requirement that a program advisor serve, although very often they do. Members of the dissertation proposal committee may be drawn from other area committees within the GSE, from other departments in the University, or from emeriti faculty. At least one person serving on the proposal committee must be from the student’s area committee (CTE, DAPS, SHIPS). All three members must be on the Academic Council; if the student desires the expertise of a non-Academic Council member, it may be possible to petition. After the hearing, a memorandum listing the changes to be made will be written and submitted with the signed proposal cover sheet and a copy of the proposal itself to the Doctoral Programs Officer.

Review and approval of the dissertation proposal occurs normally during the third year. The proposal hearing seeks to review the quality and feasibility of the proposal. The Second-Year Review and the Proposal Hearing are separate milestones and may not occur as part of the same hearing or meeting.

The student and the dissertation advisor are responsible for scheduling a formal meeting or hearing to review the proposal; the student and proposal committee convene for this evaluative period. Normally, all must be present at the meeting either in person or via conference phone call.

At the end of this meeting, the dissertation proposal committee members should sign the Cover Sheet for Dissertation Proposal and indicate their approval or rejection of the proposal. This signed form should be submitted to the Doctoral Programs Officer. If the student is required to make revisions, an addendum is required with the written approval of each member of the committee stating that the proposal has been revised to their satisfaction.

After submitting the Proposal Hearing material to the Doctoral Programs Officer, the student should make arrangements with three faculty members to serve on their Dissertation Reading Committee. The Doctoral Dissertation Reading Committee form should be completed and given to the Doctoral Programs Officer to enter in the University student records system. Note: The proposal hearing committee and the reading committee do not have to be the same three faculty members. Normally, the proposal hearing precedes the designation of a Dissertation Reading Committee, and faculty on either committee may differ (except for the primary dissertation advisor). However, some students may advance to Terminal Graduate Registration (TGR) status before completing their dissertation proposal hearing if they have established a dissertation reading committee. In these cases, it is acceptable for the student to form a reading committee prior to the dissertation proposal hearing. The reading committee then serves as the proposal committee.

The proposal and reading committee forms and related instructions are on the GSE website, under current students>forms.

Printing Credit for Use in GSE Labs

Upon completion of their doctoral dissertation proposal, GSE students are eligible for a $300 printing credit redeemable in any of the GSE computer labs where students are normally charged for print jobs. Only one $300 credit per student will be issued, but it is usable throughout the remainder of her or his doctoral program until the balance is exhausted. The print credit can be used only at the printers in Cubberley basement and CERAS, and cannot be used toward copying.

After submitting the signed dissertation proposal cover sheet to the Doctoral Programs Officer indicating approval (see above), students can submit a HELP SU ticket online at helpsu.stanford.edu to request the credit. When submitting the help ticket, the following should be selected from the drop-down menus for HELP SU:

Request Category :  Computer, Handhelds (PDAs), Printers, Servers Request Type :  Printer Operating System : (whatever system is used by the student, e.g., Windows XP.)

The help ticket will be routed to the GSE's IT Group for processing; they will in turn notify the student via email when the credit is available.

How to Write a Dissertation Proposal | A Step-by-Step Guide

Published on 14 February 2020 by Jack Caulfield . Revised on 11 November 2022.

A dissertation proposal describes the research you want to do: what it’s about, how you’ll conduct it, and why it’s worthwhile. You will probably have to write a proposal before starting your dissertation as an undergraduate or postgraduate student.

A dissertation proposal should generally include:

• An introduction to your topic and aims
• A literature review  of the current state of knowledge
• An outline of your proposed methodology
• A discussion of the possible implications of the research
• A bibliography  of relevant sources

Dissertation proposals vary a lot in terms of length and structure, so make sure to follow any guidelines given to you by your institution, and check with your supervisor when you’re unsure.

Table of contents

Step 1: coming up with an idea, step 2: presenting your idea in the introduction, step 3: exploring related research in the literature review, step 4: describing your methodology, step 5: outlining the potential implications of your research, step 6: creating a reference list or bibliography.

Before writing your proposal, it’s important to come up with a strong idea for your dissertation.

Find an area of your field that interests you and do some preliminary reading in that area. What are the key concerns of other researchers? What do they suggest as areas for further research, and what strikes you personally as an interesting gap in the field?

Once you have an idea, consider how to narrow it down and the best way to frame it. Don’t be too ambitious or too vague – a dissertation topic needs to be specific enough to be feasible. Move from a broad field of interest to a specific niche:

• Russian literature 19th century Russian literature The novels of Tolstoy and Dostoevsky
• Social media Mental health effects of social media Influence of social media on young adults suffering from anxiety

Prevent plagiarism, run a free check.

Like most academic texts, a dissertation proposal begins with an introduction . This is where you introduce the topic of your research, provide some background, and most importantly, present your aim , objectives and research question(s) .

Try to dive straight into your chosen topic: What’s at stake in your research? Why is it interesting? Don’t spend too long on generalisations or grand statements:

• Social media is the most important technological trend of the 21st century. It has changed the world and influences our lives every day.
• Psychologists generally agree that the ubiquity of social media in the lives of young adults today has a profound impact on their mental health. However, the exact nature of this impact needs further investigation.

Once your area of research is clear, you can present more background and context. What does the reader need to know to understand your proposed questions? What’s the current state of research on this topic, and what will your dissertation contribute to the field?

If you’re including a literature review, you don’t need to go into too much detail at this point, but give the reader a general sense of the debates that you’re intervening in.

This leads you into the most important part of the introduction: your aim, objectives and research question(s) . These should be clearly identifiable and stand out from the text – for example, you could present them using bullet points or bold font.

Make sure that your research questions are specific and workable – something you can reasonably answer within the scope of your dissertation. Avoid being too broad or having too many different questions. Remember that your goal in a dissertation proposal is to convince the reader that your research is valuable and feasible:

• Does social media harm mental health?
• What is the impact of daily social media use on 18– to 25–year–olds suffering from general anxiety disorder?

Now that your topic is clear, it’s time to explore existing research covering similar ideas. This is important because it shows you what is missing from other research in the field and ensures that you’re not asking a question someone else has already answered.

You’ve probably already done some preliminary reading, but now that your topic is more clearly defined, you need to thoroughly analyse and evaluate the most relevant sources in your literature review .

Here you should summarise the findings of other researchers and comment on gaps and problems in their studies. There may be a lot of research to cover, so make effective use of paraphrasing to write concisely:

• Smith and Prakash state that ‘our results indicate a 25% decrease in the incidence of mechanical failure after the new formula was applied’.
• Smith and Prakash’s formula reduced mechanical failures by 25%.

The point is to identify findings and theories that will influence your own research, but also to highlight gaps and limitations in previous research which your dissertation can address:

• Subsequent research has failed to replicate this result, however, suggesting a flaw in Smith and Prakash’s methods. It is likely that the failure resulted from…

Next, you’ll describe your proposed methodology : the specific things you hope to do, the structure of your research and the methods that you will use to gather and analyse data.

You should get quite specific in this section – you need to convince your supervisor that you’ve thought through your approach to the research and can realistically carry it out. This section will look quite different, and vary in length, depending on your field of study.

You may be engaged in more empirical research, focusing on data collection and discovering new information, or more theoretical research, attempting to develop a new conceptual model or add nuance to an existing one.

Dissertation research often involves both, but the content of your methodology section will vary according to how important each approach is to your dissertation.

Empirical research

Empirical research involves collecting new data and analysing it in order to answer your research questions. It can be quantitative (focused on numbers), qualitative (focused on words and meanings), or a combination of both.

With empirical research, it’s important to describe in detail how you plan to collect your data:

• Will you use surveys ? A lab experiment ? Interviews?
• What variables will you measure?
• How will you select a representative sample ?
• If other people will participate in your research, what measures will you take to ensure they are treated ethically?
• What tools (conceptual and physical) will you use, and why?

It’s appropriate to cite other research here. When you need to justify your choice of a particular research method or tool, for example, you can cite a text describing the advantages and appropriate usage of that method.

Don’t overdo this, though; you don’t need to reiterate the whole theoretical literature, just what’s relevant to the choices you have made.

Moreover, your research will necessarily involve analysing the data after you have collected it. Though you don’t know yet what the data will look like, it’s important to know what you’re looking for and indicate what methods (e.g. statistical tests , thematic analysis ) you will use.

Theoretical research

You can also do theoretical research that doesn’t involve original data collection. In this case, your methodology section will focus more on the theory you plan to work with in your dissertation: relevant conceptual models and the approach you intend to take.

For example, a literary analysis dissertation rarely involves collecting new data, but it’s still necessary to explain the theoretical approach that will be taken to the text(s) under discussion, as well as which parts of the text(s) you will focus on:

• This dissertation will utilise Foucault’s theory of panopticism to explore the theme of surveillance in Orwell’s 1984 and Kafka’s The Trial…

Here, you may refer to the same theorists you have already discussed in the literature review. In this case, the emphasis is placed on how you plan to use their contributions in your own research.

The only proofreading tool specialized in correcting academic writing

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

You’ll usually conclude your dissertation proposal with a section discussing what you expect your research to achieve.

You obviously can’t be too sure: you don’t know yet what your results and conclusions will be. Instead, you should describe the projected implications and contribution to knowledge of your dissertation.

First, consider the potential implications of your research. Will you:

• Develop or test a theory?
• Provide new information to governments or businesses?
• Challenge a commonly held belief?
• Suggest an improvement to a specific process?

Describe the intended result of your research and the theoretical or practical impact it will have:

Finally, it’s sensible to conclude by briefly restating the contribution to knowledge you hope to make: the specific question(s) you hope to answer and the gap the answer(s) will fill in existing knowledge:

Like any academic text, it’s important that your dissertation proposal effectively references all the sources you have used. You need to include a properly formatted reference list or bibliography at the end of your proposal.

Different institutions recommend different styles of referencing – commonly used styles include Harvard , Vancouver , APA , or MHRA . If your department does not have specific requirements, choose a style and apply it consistently.

A reference list includes only the sources that you cited in your proposal. A bibliography is slightly different: it can include every source you consulted in preparing the proposal, even if you didn’t mention it in the text. In the case of a dissertation proposal, a bibliography may also list relevant sources that you haven’t yet read, but that you intend to use during the research itself.

Check with your supervisor what type of bibliography or reference list you should include.

How to write a research proposal

What is a research proposal.

A research proposal should present your idea or question and expected outcomes with clarity and definition – the what.

It should also make a case for why your question is significant and what value it will bring to your discipline – the why. 

What it shouldn't do is answer the question – that's what your research will do.

Why is it important?

Research proposals are significant because Another reason why it formally outlines your intended research. Which means you need to provide details on how you will go about your research, including:

• your approach and methodology
• timeline and feasibility
• all other considerations needed to progress your research, such as resources.

Think of it as a tool that will help you clarify your idea and make conducting your research easier.

How long should it be?

Usually no more than 2000 words, but check the requirements of your degree, and your supervisor or research coordinator.

Presenting your idea clearly and concisely demonstrates that you can write this way – an attribute of a potential research candidate that is valued by assessors.

What should it include?

Project title.

Your title should clearly indicate what your proposed research is about.

Research supervisor

State the name, department and faculty or school of the academic who has agreed to supervise you. Rest assured, your research supervisor will work with you to refine your research proposal ahead of submission to ensure it meets the needs of your discipline.

Proposed mode of research

Describe your proposed mode of research. Which may be closely linked to your discipline, and is where you will describe the style or format of your research, e.g. data, field research, composition, written work, social performance and mixed media etc. 

This is not required for research in the sciences, but your research supervisor will be able to guide you on discipline-specific requirements.

Aims and objectives

What are you trying to achieve with your research? What is the purpose? This section should reference why you're applying for a research degree. Are you addressing a gap in the current research? Do you want to look at a theory more closely and test it out? Is there something you're trying to prove or disprove? To help you clarify this, think about the potential outcome of your research if you were successful – that is your aim. Make sure that this is a focused statement.

Your objectives will be your aim broken down – the steps to achieving the intended outcome. They are the smaller proof points that will underpin your research's purpose. Be logical in the order of how you present these so that each succeeds the previous, i.e. if you need to achieve 'a' before 'b' before 'c', then make sure you order your objectives a, b, c.

A concise summary of what your research is about. It outlines the key aspects of what you will investigate as well as the expected outcomes. It briefly covers the what, why and how of your research. 

A good way to evaluate if you have written a strong synopsis, is to get somebody to read it without reading the rest of your research proposal. Would they know what your research is about?

Now that you have your question clarified, it is time to explain the why. Here, you need to demonstrate an understanding of the current research climate in your area of interest.

Providing context around your research topic through a literature review will show the assessor that you understand current dialogue around your research, and what is published.

Demonstrate you have a strong understanding of the key topics, significant studies and notable researchers in your area of research and how these have contributed to the current landscape.

Expected research contribution

In this section, you should consider the following:

• Why is your research question or hypothesis worth asking?
• How is the current research lacking or falling short?
• What impact will your research have on the discipline?
• Will you be extending an area of knowledge, applying it to new contexts, solving a problem, testing a theory, or challenging an existing one?
• Establish why your research is important by convincing your audience there is a gap.
• What will be the outcome of your research contribution?
• Demonstrate both your current level of knowledge and how the pursuit of your question or hypothesis will create a new understanding and generate new information.
• Show how your research is innovative and original.

Draw links between your research and the faculty or school you are applying at, and explain why you have chosen your supervisor, and what research have they or their school done to reinforce and support your own work. Cite these reasons to demonstrate how your research will benefit and contribute to the current body of knowledge.

Proposed methodology

Provide an overview of the methodology and techniques you will use to conduct your research. Cover what materials and equipment you will use, what theoretical frameworks will you draw on, and how will you collect data.

Highlight why you have chosen this particular methodology, but also why others may not have been as suitable. You need to demonstrate that you have put thought into your approach and why it's the most appropriate way to carry out your research. 

It should also highlight potential limitations you anticipate, feasibility within time and other constraints, ethical considerations and how you will address these, as well as general resources.

A work plan is a critical component of your research proposal because it indicates the feasibility of completion within the timeframe and supports you in achieving your objectives throughout your degree.

Consider the milestones you aim to achieve at each stage of your research. A PhD or master's degree by research can take two to four years of full-time study to complete. It might be helpful to offer year one in detail and the following years in broader terms. Ultimately you have to show that your research is likely to be both original and finished – and that you understand the time involved.

Provide details of the resources you will need to carry out your research project. Consider equipment, fieldwork expenses, travel and a proposed budget, to indicate how realistic your research proposal is in terms of financial requirements and whether any adjustments are needed.

Bibliography

Provide a list of references that you've made throughout your research proposal.

Writing a research proposal

Guidelines on preparing a thesis proposal to support your application.

These guidelines are intended to assist you in developing and writing a thesis proposal. Applications for admission to a research degree cannot be dealt with unless they contain a proposal.

Your proposal will help us to make sure that:

• The topic is viable
• That the department can provide appropriate supervision and other necessary support
• You have thought through your interest in and commitment to a piece of research
• You are a suitable candidate for admission

The process of producing a proposal is usually also essential if you need to apply for funding to pay your fees or support yourself whilst doing your research. Funding bodies will often need to be reassured that you are committed to a viable project at a suitable university.

The research proposal – an outline

Your proposal should be typed double-spaced, if possible, and be between 1,000 and 2,000 words. Your PhD proposal can be added under the 'Supporting Documents' section of the Postgraduate Applications Online System .

Your proposal should contain at least the following elements:

• A provisional title
• A key question, hypothesis or the broad topic for investigation
• An outline of the key aims of the research
• A brief outline of key literature in the area [what we already know]
• A description of the topic and an explanation of why further research in the area is important [the gap in the literature - what we need to know]
• Details of how the research will be carried out, including any special facilities / resources etc. which would be required and any necessary skills which you either have already or would need to acquire [the tools that will enable us to fill the gap you have identified]
• A plan and timetable of the work you will carry out

For more detailed information on each element of your research proposal, see our extended guidance document .

Three additional points:

• Try to be concise. Do not write too much – be as specific as you can but not wordy. It is a difficult balance to strike.
• Bear in mind that the proposal is a starting point. If you are registered to read for a PhD you will be able to work the proposal through with your supervisor in more detail in the early months.
• Take a look at the Department’s staff profiles, research centres, and research clusters. Can you identify possible supervisors and intellectual support networks within the Department?

Welcome to the on-line version of the UNC dissertation proposal collection. The purpose of this collection is to provide examples of proposals for those of you who are thinking of writing a proposal of your own. I hope that this on-line collection proves to be more difficult to misplace than the physical collection that periodically disappears. If you are preparing to write a proposal you should make a point of reading the excellent document The Path to the Ph.D., written by James Coggins. It includes advice about selecting a topic, preparing a proposal, taking your oral exam and finishing your dissertation. It also includes accounts by many people about the process that each of them went through to find a thesis topic. Adding to the Collection This collection of proposals becomes more useful with each new proposal that is added. If you have an accepted proposal, please help by including it in this collection. You may notice that the bulk of the proposals currently in this collection are in the area of computer graphics. This is an artifact of me knowing more computer graphics folks to pester for their proposals. Add your non-graphics proposal to the collection and help remedy this imbalance! There are only two requirements for a UNC proposal to be added to this collection. The first requirement is that your proposal must be completely approved by your committee. If we adhere to this, then each proposal in the collection serves as an example of a document that five faculty members have signed off on. The second requirement is that you supply, as best you can, exactly the document that your committee approved. While reading over my own proposal I winced at a few of the things that I had written. I resisted the temptation to change the document, however, because this collection should truely reflect what an accepted thesis proposal looks like. Note that there is no requirement that the author has finished his/her Ph.D. Several of the proposals in the collection were written by people who, as of this writing, are still working on their dissertation. This is fine! I encourage people to submit their proposals in any form they wish. Perhaps the most useful forms at the present are Postscript and HTML, but this may not always be so. Greg Coombe has generously provided LaTeX thesis style files , which, he says, conform to the 2004-2005 stlye requirements.

Many thanks to everyone who contributed to this collection!

By: Derek Jansen (MBA) Expert Reviewed By: Dr Eunice Rautenbach | June 2020

Writing a dissertation or thesis is not a simple task. It takes time, energy and a lot of will power to get you across the finish line. It’s not easy – but it doesn’t necessarily need to be a painful process. If you understand the big-picture process of how to write a dissertation or thesis, your research journey will be a lot smoother.  

In this post, I’m going to outline the big-picture process of how to write a high-quality dissertation or thesis, without losing your mind along the way. If you’re just starting your research, this post is perfect for you. Alternatively, if you’ve already submitted your proposal, this article which covers how to structure a dissertation might be more helpful.

How To Write A Dissertation: 8 Steps

• Clearly understand what a dissertation (or thesis) is
• Find a unique and valuable research topic
• Craft a convincing research proposal
• Write up a strong introduction chapter
• Review the existing literature and compile a literature review
• Design a rigorous research strategy and undertake your own research
• Present the findings of your research
• Draw a conclusion and discuss the implications

Step 1: Understand exactly what a dissertation is

This probably sounds like a no-brainer, but all too often, students come to us for help with their research and the underlying issue is that they don’t fully understand what a dissertation (or thesis) actually is.

So, what is a dissertation?

At its simplest, a dissertation or thesis is a formal piece of research , reflecting the standard research process . But what is the standard research process, you ask? The research process involves 4 key steps:

• Ask a very specific, well-articulated question (s) (your research topic)
• See what other researchers have said about it (if they’ve already answered it)
• If they haven’t answered it adequately, undertake your own data collection and analysis in a scientifically rigorous fashion
• Answer your original question(s), based on your analysis findings

In short, the research process is simply about asking and answering questions in a systematic fashion . This probably sounds pretty obvious, but people often think they’ve done “research”, when in fact what they have done is:

• Started with a vague, poorly articulated question
• Not taken the time to see what research has already been done regarding the question
• Collected data and opinions that support their gut and undertaken a flimsy analysis
• Drawn a shaky conclusion, based on that analysis

If you want to see the perfect example of this in action, look out for the next Facebook post where someone claims they’ve done “research”… All too often, people consider reading a few blog posts to constitute research. Its no surprise then that what they end up with is an opinion piece, not research. Okay, okay – I’ll climb off my soapbox now.

The key takeaway here is that a dissertation (or thesis) is a formal piece of research, reflecting the research process. It’s not an opinion piece , nor a place to push your agenda or try to convince someone of your position. Writing a good dissertation involves asking a question and taking a systematic, rigorous approach to answering it.

If you understand this and are comfortable leaving your opinions or preconceived ideas at the door, you’re already off to a good start!

Step 2: Find a unique, valuable research topic

As we saw, the first step of the research process is to ask a specific, well-articulated question. In other words, you need to find a research topic that asks a specific question or set of questions (these are called research questions ). Sounds easy enough, right? All you’ve got to do is identify a question or two and you’ve got a winning research topic. Well, not quite…

A good dissertation or thesis topic has a few important attributes. Specifically, a solid research topic should be:

Let’s take a closer look at these:

Attribute #1: Clear

Your research topic needs to be crystal clear about what you’re planning to research, what you want to know, and within what context. There shouldn’t be any ambiguity or vagueness about what you’ll research.

Here’s an example of a clearly articulated research topic:

An analysis of consumer-based factors influencing organisational trust in British low-cost online equity brokerage firms.

As you can see in the example, its crystal clear what will be analysed (factors impacting organisational trust), amongst who (consumers) and in what context (British low-cost equity brokerage firms, based online).

Need a helping hand?

Attribute #2:   Unique

Your research should be asking a question(s) that hasn’t been asked before, or that hasn’t been asked in a specific context (for example, in a specific country or industry).

For example, sticking organisational trust topic above, it’s quite likely that organisational trust factors in the UK have been investigated before, but the context (online low-cost equity brokerages) could make this research unique. Therefore, the context makes this research original.

One caveat when using context as the basis for originality – you need to have a good reason to suspect that your findings in this context might be different from the existing research – otherwise, there’s no reason to warrant researching it.

Attribute #3: Important

Simply asking a unique or original question is not enough – the question needs to create value. In other words, successfully answering your research questions should provide some value to the field of research or the industry. You can’t research something just to satisfy your curiosity. It needs to make some form of contribution either to research or industry.

For example, researching the factors influencing consumer trust would create value by enabling businesses to tailor their operations and marketing to leverage factors that promote trust. In other words, it would have a clear benefit to industry.

So, how do you go about finding a unique and valuable research topic? We explain that in detail in this video post – How To Find A Research Topic . Yeah, we’ve got you covered 😊

Step 3: Write a convincing research proposal

Once you’ve pinned down a high-quality research topic, the next step is to convince your university to let you research it. No matter how awesome you think your topic is, it still needs to get the rubber stamp before you can move forward with your research. The research proposal is the tool you’ll use for this job.

So, what’s in a research proposal?

The main “job” of a research proposal is to convince your university, advisor or committee that your research topic is worthy of approval. But convince them of what? Well, this varies from university to university, but generally, they want to see that:

• You have a clearly articulated, unique and important topic (this might sound familiar…)
• You’ve done some initial reading of the existing literature relevant to your topic (i.e. a literature review)
• You have a provisional plan in terms of how you will collect data and analyse it (i.e. a methodology)

At the proposal stage, it’s (generally) not expected that you’ve extensively reviewed the existing literature , but you will need to show that you’ve done enough reading to identify a clear gap for original (unique) research. Similarly, they generally don’t expect that you have a rock-solid research methodology mapped out, but you should have an idea of whether you’ll be undertaking qualitative or quantitative analysis , and how you’ll collect your data (we’ll discuss this in more detail later).

Long story short – don’t stress about having every detail of your research meticulously thought out at the proposal stage – this will develop as you progress through your research. However, you do need to show that you’ve “done your homework” and that your research is worthy of approval .

So, how do you go about crafting a high-quality, convincing proposal? We cover that in detail in this video post – How To Write A Top-Class Research Proposal . We’ve also got a video walkthrough of two proposal examples here .

Step 4: Craft a strong introduction chapter

Once your proposal’s been approved, its time to get writing your actual dissertation or thesis! The good news is that if you put the time into crafting a high-quality proposal, you’ve already got a head start on your first three chapters – introduction, literature review and methodology – as you can use your proposal as the basis for these.

What’s the introduction chapter all about?

The purpose of the introduction chapter is to set the scene for your research (dare I say, to introduce it…) so that the reader understands what you’ll be researching and why it’s important. In other words, it covers the same ground as the research proposal in that it justifies your research topic.

What goes into the introduction chapter?

This can vary slightly between universities and degrees, but generally, the introduction chapter will include the following:

• A brief background to the study, explaining the overall area of research
• A problem statement , explaining what the problem is with the current state of research (in other words, where the knowledge gap exists)
• Your research questions – in other words, the specific questions your study will seek to answer (based on the knowledge gap)
• The significance of your study – in other words, why it’s important and how its findings will be useful in the world

As you can see, this all about explaining the “what” and the “why” of your research (as opposed to the “how”). So, your introduction chapter is basically the salesman of your study, “selling” your research to the first-time reader and (hopefully) getting them interested to read more.

How do I write the introduction chapter, you ask? We cover that in detail in this post .

Step 5: Undertake an in-depth literature review

As I mentioned earlier, you’ll need to do some initial review of the literature in Steps 2 and 3 to find your research gap and craft a convincing research proposal – but that’s just scratching the surface. Once you reach the literature review stage of your dissertation or thesis, you need to dig a lot deeper into the existing research and write up a comprehensive literature review chapter.

What’s the literature review all about?

There are two main stages in the literature review process:

Literature Review Step 1: Reading up

The first stage is for you to deep dive into the existing literature (journal articles, textbook chapters, industry reports, etc) to gain an in-depth understanding of the current state of research regarding your topic. While you don’t need to read every single article, you do need to ensure that you cover all literature that is related to your core research questions, and create a comprehensive catalogue of that literature , which you’ll use in the next step.

Reading and digesting all the relevant literature is a time consuming and intellectually demanding process. Many students underestimate just how much work goes into this step, so make sure that you allocate a good amount of time for this when planning out your research. Thankfully, there are ways to fast track the process – be sure to check out this article covering how to read journal articles quickly .

Literature Review Step 2: Writing up

Once you’ve worked through the literature and digested it all, you’ll need to write up your literature review chapter. Many students make the mistake of thinking that the literature review chapter is simply a summary of what other researchers have said. While this is partly true, a literature review is much more than just a summary. To pull off a good literature review chapter, you’ll need to achieve at least 3 things:

• You need to synthesise the existing research , not just summarise it. In other words, you need to show how different pieces of theory fit together, what’s agreed on by researchers, what’s not.
• You need to highlight a research gap that your research is going to fill. In other words, you’ve got to outline the problem so that your research topic can provide a solution.
• You need to use the existing research to inform your methodology and approach to your own research design. For example, you might use questions or Likert scales from previous studies in your your own survey design .

As you can see, a good literature review is more than just a summary of the published research. It’s the foundation on which your own research is built, so it deserves a lot of love and attention. Take the time to craft a comprehensive literature review with a suitable structure .

But, how do I actually write the literature review chapter, you ask? We cover that in detail in this video post .

Step 6: Carry out your own research

Once you’ve completed your literature review and have a sound understanding of the existing research, its time to develop your own research (finally!). You’ll design this research specifically so that you can find the answers to your unique research question.

There are two steps here – designing your research strategy and executing on it:

1 – Design your research strategy

The first step is to design your research strategy and craft a methodology chapter . I won’t get into the technicalities of the methodology chapter here, but in simple terms, this chapter is about explaining the “how” of your research. If you recall, the introduction and literature review chapters discussed the “what” and the “why”, so it makes sense that the next point to cover is the “how” –that’s what the methodology chapter is all about.

In this section, you’ll need to make firm decisions about your research design. This includes things like:

• Your research philosophy (e.g. positivism or interpretivism )
• Your overall methodology (e.g. qualitative , quantitative or mixed methods)
• Your data collection strategy (e.g. interviews , focus groups, surveys)
• Your data analysis strategy (e.g. content analysis , correlation analysis, regression)

If these words have got your head spinning, don’t worry! We’ll explain these in plain language in other posts. It’s not essential that you understand the intricacies of research design (yet!). The key takeaway here is that you’ll need to make decisions about how you’ll design your own research, and you’ll need to describe (and justify) your decisions in your methodology chapter.

2 – Execute: Collect and analyse your data

Once you’ve worked out your research design, you’ll put it into action and start collecting your data. This might mean undertaking interviews, hosting an online survey or any other data collection method. Data collection can take quite a bit of time (especially if you host in-person interviews), so be sure to factor sufficient time into your project plan for this. Oftentimes, things don’t go 100% to plan (for example, you don’t get as many survey responses as you hoped for), so bake a little extra time into your budget here.

Once you’ve collected your data, you’ll need to do some data preparation before you can sink your teeth into the analysis. For example:

• If you carry out interviews or focus groups, you’ll need to transcribe your audio data to text (i.e. a Word document).
• If you collect quantitative survey data, you’ll need to clean up your data and get it into the right format for whichever analysis software you use (for example, SPSS, R or STATA).

Once you’ve completed your data prep, you’ll undertake your analysis, using the techniques that you described in your methodology. Depending on what you find in your analysis, you might also do some additional forms of analysis that you hadn’t planned for. For example, you might see something in the data that raises new questions or that requires clarification with further analysis.

The type(s) of analysis that you’ll use depend entirely on the nature of your research and your research questions. For example:

• If your research if exploratory in nature, you’ll often use qualitative analysis techniques .
• If your research is confirmatory in nature, you’ll often use quantitative analysis techniques
• If your research involves a mix of both, you might use a mixed methods approach

Again, if these words have got your head spinning, don’t worry! We’ll explain these concepts and techniques in other posts. The key takeaway is simply that there’s no “one size fits all” for research design and methodology – it all depends on your topic, your research questions and your data. So, don’t be surprised if your study colleagues take a completely different approach to yours.

Step 7: Present your findings

Once you’ve completed your analysis, it’s time to present your findings (finally!). In a dissertation or thesis, you’ll typically present your findings in two chapters – the results chapter and the discussion chapter .

What’s the difference between the results chapter and the discussion chapter?

While these two chapters are similar, the results chapter generally just presents the processed data neatly and clearly without interpretation, while the discussion chapter explains the story the data are telling  – in other words, it provides your interpretation of the results.

For example, if you were researching the factors that influence consumer trust, you might have used a quantitative approach to identify the relationship between potential factors (e.g. perceived integrity and competence of the organisation) and consumer trust. In this case:

• Your results chapter would just present the results of the statistical tests. For example, correlation results or differences between groups. In other words, the processed numbers.
• Your discussion chapter would explain what the numbers mean in relation to your research question(s). For example, Factor 1 has a weak relationship with consumer trust, while Factor 2 has a strong relationship.

Depending on the university and degree, these two chapters (results and discussion) are sometimes merged into one , so be sure to check with your institution what their preference is. Regardless of the chapter structure, this section is about presenting the findings of your research in a clear, easy to understand fashion.

Importantly, your discussion here needs to link back to your research questions (which you outlined in the introduction or literature review chapter). In other words, it needs to answer the key questions you asked (or at least attempt to answer them).

For example, if we look at the sample research topic:

In this case, the discussion section would clearly outline which factors seem to have a noteworthy influence on organisational trust. By doing so, they are answering the overarching question and fulfilling the purpose of the research .

For more information about the results chapter , check out this post for qualitative studies and this post for quantitative studies .

Step 8: The Final Step Draw a conclusion and discuss the implications

Last but not least, you’ll need to wrap up your research with the conclusion chapter . In this chapter, you’ll bring your research full circle by highlighting the key findings of your study and explaining what the implications of these findings are.

What exactly are key findings? The key findings are those findings which directly relate to your original research questions and overall research objectives (which you discussed in your introduction chapter). The implications, on the other hand, explain what your findings mean for industry, or for research in your area.

Sticking with the consumer trust topic example, the conclusion might look something like this:

Key findings

This study set out to identify which factors influence consumer-based trust in British low-cost online equity brokerage firms. The results suggest that the following factors have a large impact on consumer trust:

While the following factors have a very limited impact on consumer trust:

Notably, within the 25-30 age groups, Factors E had a noticeably larger impact, which may be explained by…

Implications

The findings having noteworthy implications for British low-cost online equity brokers. Specifically:

The large impact of Factors X and Y implies that brokers need to consider….

The limited impact of Factor E implies that brokers need to…

As you can see, the conclusion chapter is basically explaining the “what” (what your study found) and the “so what?” (what the findings mean for the industry or research). This brings the study full circle and closes off the document.

Let’s recap – how to write a dissertation or thesis

You’re still with me? Impressive! I know that this post was a long one, but hopefully you’ve learnt a thing or two about how to write a dissertation or thesis, and are now better equipped to start your own research.

To recap, the 8 steps to writing a quality dissertation (or thesis) are as follows:

• Understand what a dissertation (or thesis) is – a research project that follows the research process.
• Find a unique (original) and important research topic
• Craft a convincing dissertation or thesis research proposal
• Write a clear, compelling introduction chapter
• Undertake a thorough review of the existing research and write up a literature review
• Undertake your own research
• Present and interpret your findings

Once you’ve wrapped up the core chapters, all that’s typically left is the abstract , reference list and appendices. As always, be sure to check with your university if they have any additional requirements in terms of structure or content.  

Psst... there’s more!

Thanks for the feedback and suggestions 🙂

Hello, your write ups is quite educative. However, l have challenges in going about my research questions which is below; *Building the enablers of organisational growth through effective governance and purposeful leadership.*

Very educating.

Just listening to the name of the dissertation makes the student nervous. As writing a top-quality dissertation is a difficult task as it is a lengthy topic, requires a lot of research and understanding and is usually around 10,000 to 15000 words. Sometimes due to studies, unbalanced workload or lack of research and writing skill students look for dissertation submission from professional writers.

Thank you 💕😊 very much. I was confused but your comprehensive explanation has cleared my doubts of ever presenting a good thesis. Thank you.

thank you so much, that was so useful

Thesis Proposal

In the thesis proposal, the PhD or DES student lays out an intended course of research for the dissertation.  By accepting the thesis proposal, the student’s dissertation proposal committee agrees that the proposal is practicable and acceptable, that its plan and prospectus are satisfactory, and that the candidate is competent in the knowledge and techniques required, and formally recommends that the candidate proceed according to the prospectus and under the supervision of the dissertation committee. It is part of the training of the student’s research apprenticeship that the form of this proposal must be as concise as those proposals required by major funding agencies.

The student proposes to a committee consisting of the student’s advisor and two other researchers who meet requirements for dissertation committee membership.  The advisor should solicit the prospective committee members, not the student. In cases where the research and departmental advisors are different , both must serve on the committee.

The student prepares a proposal document that consists of a core, plus any optional appendices. The core is limited to 30 pages (e.g., 12 point font, single spacing, 1 inch margins all around), and should contain sections describing 1) the problem and its background, 2) the innovative claims of the proposed work and its relation to existing work, 3) a description of at least one initial result that is mature enough to be able to be written up for submission to a conference, and 4) a plan for completion of the research. The committee commits to read and respond to the core, but reserves the right to refuse a document whose core exceeds the page limit. The student cannot assume that the committee will read or respond to any additional appendices.

The complete doctoral thesis proposal document must be disseminated to the entire dissertation committee no later than two weeks (14 days) prior to the proposal presentation. The PhD Program Administrator must be informed of the scheduling of the proposal presentation no later than two weeks (14 days) prior to the presentation. Emergency exceptions to either of these deadlines can be granted by the Director of Graduate Studies or the Department Chair on appeal by the advisor and agreement of the committee.

A latex thesis proposal template is available here .

PRESENTATION AND FEEDBACK

The student presents the proposal in a prepared talk of 45 minutes to the committee, and responds to any questions and feedback by the committee.

The student’s advisor, upon approval of the full faculty, establishes the target semester by which the thesis proposal must be successfully completed. The target semester must be no later than the eighth semester, and the student must be informed of the target semester no later than the sixth semester.

The candidacy   exam  must be successfully completed  before  the  proposal can be attempted.  The proposal must be completed prior to submitting the application for defense. [Instituted by full faculty vote September 16, 2015.]

Passing or failing is determined by consensus of the committee, who then sign the dissertation proposal form (sent to advisors by phd-advising@cs.  Failure to pass the thesis proposal by the end of the target semester or the eighth semester, whichever comes first, is deemed unsatisfactory progress: the PhD or DES student is normally placed on probation and can be immediately dismissed from the program. However, on appeal of the student’s advisor, one semester’s grace can be granted by the full faculty.

will propose a doctoral thesis entitled,

Sustainable materials and designs for advanced electrospinning

Monday, May 20 at 1:00 p.m.

MoSE Room 1224

Electrospinning offers unique opportunities for producing ultrafine fibers with diverse applications, yet formulating polymer solutions for this technique remains challenging. The complexity of formulation, particularly concerning sustainability, necessitates innovative approaches to address key issues. For example, the pervasive use of petroleum-derived polymers in electrospinning formulations, notably in critical items like disposable face masks, contributes substantially to plastic waste accumulation. This dilemma emphasizes the need to explore alternative polymer formulation approaches, such as leveraging bioderived polymers, utilizing green solvents, or enhancing degradation mechanisms at the end of the product lifecycle, mitigating environmental impact. Furthermore, traditional methods of formulation often rely on trial-and-error approaches, leading to inefficiencies and environmental concerns. The central problem addressed in this thesis is the need to enhance sustainability in electrospinning by expanding formulation processes and materials. To address this challenge, the goal of this research is to develop formulations addressing these components—polymer, solvent, and additive—to provide comprehensive solutions for advancing sustainability in electrospinning.

For the polymer component of electrospinning formulations, guidelines for the electrospinnability of charged biopolymers is explored through the interplay between conductivity, viscosity, and polymer concentration (Aim 1). In studying sodium alginate, conductivity is identified as a critical variable guiding the formulation process, broadening the design space for sustainable biopolymer-based fibers. For the solvent component of electrospinning formulations, data-driven material selection methodologies are proposed to expedite the identification of green solvents for polymer blends (Aim 2). By leveraging existing databases, this approach streamlines the selection process by analyzing polymer-solvent interactions and environmental criteria, reducing the number of experiments required and accelerating the development of sustainable electrospinning formulations. Through the additive component of electrospinning formulations, triggerable plastic degradation is introduced through enzyme encapsulation in polymer matrices (Aim 3). By incorporating proteinase and lipase enzymes into PLA and PCL formulations, respectively, the aim is to enhance biodegradability and promote sustainability in plastic materials. Through systematic investigations into enzyme activity, membrane architecture, and degradation kinetics, this approach offers a novel strategy for addressing end-of-life scenarios in electrospinning products. I aim to diversify the materials available for electrospinning formulations beyond synthetic and petroleum-based materials by  integrating sustainability considerations for all formulation components.
