PhD Research Proposal Guide: What Top Universities Actually Require

At most UK and European universities, the research proposal is the centerpiece of your PhD application—not the personal statement. This is fundamentally different from the US model, where the statement of purpose does most of the heavy lifting.

If you're applying to Oxford, Cambridge, LSE, or any European research university, your proposal needs to demonstrate that your project is original, viable, and achievable within three to four years.

The key difference:

LSE's Management Department states: "Your research proposal will play a particularly significant role in the evaluation of your application." At some LSE departments, applications without a research proposal simply won't be considered.

How UK/EU PhD applications differ from US ones

In the US, you typically apply to a department and write a statement of purpose about your research interests and fit. The SOP does the main work.

In the UK and Europe, you often need both a research proposal AND a personal statement or motivation letter—and the proposal carries more weight.

University of Oxford DPhil proposals

Oxford's official guidance provides detailed instructions, but requirements vary significantly by department.

Word limits by department

• Geography and the Environment: ~2,500 words
• Education: max 2,500 words (excluding bibliography)
• Law (Centre for Socio-Legal Studies): max 2,000 words
• Blavatnik School of Government: 4,000-6,000 words
• Oxford Internet Institute: up to 15,000 words

Oxford's central guidance: "You should read your course page to find instructions for what to include in your research proposal, how your department will assess it, and the required word count."

Structure

Oxford recommends:

1. Introduction — "State your research question(s) as succinctly and clearly as you can. It's best to frame your project around an intellectual problem, paradox or debate."
2. Research Goals and Methods — Outline main goals and demonstrate facility with the topic
3. Research Methods — Explain how you plan to conduct the research
4. Chapter Outline (tentative) — "Can help to show that you are committed to the research"
5. Bibliography — Not included in the word count

Evaluation criteria

Oxford assesses proposals for:

1. Coherence and viability of the project
2. Originality
3. Feasibility of completion within three to four years
4. Evidence of understanding appropriate research skills
5. Evidence of appropriate training at master's level

The combined document requirement

This catches many applicants off guard. Oxford requires the SOP and research proposal as one combined document:

"If your course requires both a statement of purpose and a research proposal, you should submit them within the same document with a clear subheading for each. There is only one document slot for this type of material on the application form."

University of Cambridge PhD proposals

Cambridge's proposal guidance also varies by department, but with some helpful specifics.

Word limits by department

• Faculty of English: 800 words (PhD)
• Faculty of Education: 1,500 words
• Centre of Latin American Studies: 1,000-1,500 words (excluding references)
• Faculty of Law: 2,000-3,000 words

Cambridge advises: "Before you start, you should check the maximum word count and character limit, as well as what's included in the word count—for example, footnotes."

Structure (from the Faculty of English)

The Faculty of English provides detailed guidance:

1. Research Topic — "Briefly outline the area and topic of your research"
2. Research Context — "Relate your proposed research to other work in its field"
3. Contribution to Knowledge — "Show how you have arrived at your position and recognised the need for your research"
4. Methodology — "If there is something striking about your methodology, you should explain it"
5. Sources and Resources — "In certain cases, Cambridge will have unique collections and resources of central relevance to your project"

What assessors evaluate

Cambridge assessors look at whether:

• You are suitable for a PhD (intelligent, qualified, a self-starter, driven)
• Your project is valuable, achievable, and fits with a supervisor
• You will see it through when it gets hard

Writing quality matters: "It should be written in clear, jargon-free prose, and grammatical mistakes and typographical errors give a very bad impression."

Separate from personal statement

Unlike Oxford, Cambridge keeps the personal statement and research proposal as separate documents: "Keep your content focused on yourself as a potential PhD researcher by making sure it's separate from your research proposal."

London School of Economics PhD proposals

LSE treats the research proposal as central to the application. Their guidance states that "applications without a research proposal will not be considered."

Word limits

• General guidance: ~1,500 words
• Social Policy: up to 4,000 words with abstract (300 words max)
• Political Science: ~2,000 words
• Anthropology: 8,000-10,000 words (excluding references)

What to include

LSE describes the proposal as "a crisp and concise statement of the research you're undertaking" that should:

1. Identify a gap in preceding scholarship
2. Articulate the significance of the gap
3. Create space for yourself within the field

Specific questions to address:

• What is your general topic?
• What questions do you want to answer?
• What is the key literature and its limitations?
• What methodology do you intend to use?
• What theoretical/conceptual framework will you adopt?

Two separate documents

LSE requires a Statement of Academic Purpose (1,000-1,500 words) AND a Research Proposal. The Management Department explains the distinction: the SoAP is about you and your fit; the research proposal is about the project and its scholarly merit.

A living document

Once admitted, "your research proposal will be considered a 'living document' throughout your time with the Department, and not a fully binding commitment."

University College London PhD proposals

UCL typically expects proposals of 1,000-1,500 words, though some departments allow up to 3,000.

Structure

UCL proposals should include:

• A title
• An overview of existing scholarship
• Specific research questions and methodology
• A clear statement about your methodological approach
• A provisional chapter outline
• Only key references (not a lengthy reference list)

The proposal should "clearly state the research question and its importance, provide specific details of experimental or other kinds of studies, and demonstrate logical thinking, clear design, and relevant methodological knowledge."

Supervisor contact first

UCL typically expects you to contact a potential supervisor before applying. From their guidance: "Enquiries to potential supervisors should be accompanied by a CV and initial research proposal."

ETH Zurich doctoral applications

ETH Zurich works fundamentally differently from UK universities. There is no centralized research proposal at the application stage.

"You must find a professor at ETH Zurich who will offer you a doctoral position. It is only possible to register for a doctorate once you have found a doctoral position."

Motivation letter

• ETH AI Center Doctoral Fellowships: 1-2 pages outlining research area of interest
• GTA Doctoral Programme: Should state how the doctorate supports your career and why ETH is a suitable host

Project outline (GTA Programme)

The GTA programme provides detailed requirements:

• Maximum 5 pages (including tables, images, footnotes; excluding bibliography)
• Must include: objectives, hypothesis/research question, methods, scientific relevance, intended outputs, and a schedule for completion within three years

KU Leuven: the supervisor-first model

KU Leuven operates on a supervisor-initiated model that's common across Belgian and Dutch universities.

"You cannot initiate the application procedure yourself. Your KU Leuven supervisor will start up the application procedure on your behalf."

Two routes to a supervisor

Route 1: Apply for a vacant PhD position on the KU Leuven jobsite.

Route 2: Contact a potential supervisor directly. Email your research proposal, motivation letter, CV, and transcripts.

Proposal requirements

The proposal must be:

• Original and innovative
• Clear, focused, and feasible within 4 years (48 months)
• Positively evaluated by the doctoral committee

How the proposal relates to your SOP

This is the critical question. The answer depends on the university:

The general rule: your SOP/personal statement explains who you are and why this program. Your research proposal explains what you will study and how.

Don't duplicate content between them.

Common mistakes to avoid

1. Using a US-style SOP as your proposal — A narrative about your research interests is not a research proposal
2. Ignoring department-specific requirements — Word limits vary from 800 to 15,000 within the same university
3. Vague research questions — "I'm interested in studying X" is not a proposal
4. Missing feasibility — You must convince readers the project can be completed in 3-4 years
5. No literature engagement — Show you know what's already been done
6. Not contacting supervisors — At most UK/EU universities, this is expected before you apply
7. Combining SOP and proposal when they should be separate (or vice versa)
