How to Find a Thesis Topic: Step by Step

To find a thesis topic that works, it should meet four conditions. It must interest you, it must narrow down to a concrete research question, it must be feasible with the data and time available, and a supervisor must be willing to supervise it. If you work through these in this order, you make the decision on a solid basis. This applies equally to a bachelor’s thesis and a master’s thesis.

Key points at a glance

• A topic is an area, while a research question is an answerable question within that area. The thesis needs the latter.
• The best starting points are your own seminar papers, research gaps in recent academic articles and practical problems from a part-time job or internship.
• Check whether literature, data and timeframe are sufficient before you decide. More theses fail on this than on a lack of interest.
• Talk to possible supervisors early. A short exposé makes the conversation much easier.
• Registration deadlines, forms and topic requirements are set out in the examination regulations of your degree programme.

How do you find a thesis topic?

The best place to start is with what you already know. Go through your seminar and term papers, lecture notes and reading lists, and mark anything that kept you busy for a long time. A term paper that left questions open at the end often becomes the best thesis topic, because you already know the basics.

These sources provide usable ideas:

• Your own coursework: Which course or term paper sparked your curiosity? Which question remained unanswered?
• Current academic literature: Articles and dissertations often end with hints about open questions or suggestions for further research. These are ready-made topic ideas.
• Practice: A part-time job, internship or working student role provides concrete problems that can be studied scientifically.
• Chairs: Many chairs publish topic lists or research focuses on their website. It is worth a look before you develop your own ideas.
• Current debates: Social and academic discussions can serve as a starting point, but they need scholarly literature you can build on.

Write down each idea in one sentence without judging it. From the collection, you select the most promising candidates in the next step.

Which topic suits you and your degree programme?

The right topic combines your interest with your methodological skills and the profile of your subject. For each candidate, ask yourself: Do I want to spend half a year on this? Do I trust myself with the necessary method, such as statistics, interviews or text analysis? Does the topic fit what your degree programme accepts as a thesis?

Criterion	Guiding question
Interest	Does the topic keep me engaged even when the work gets tough?
Method	Do I master the method, or can I learn it in time?
Subject fit	Will my examination office assign the topic to my degree programme?
Data and literature	Are there enough sources, and can I access the data?
Supervision	Does someone at the chair know the field?
Prospects	Will the topic help me with applications or my career start?

For a master’s thesis, examiners usually expect more independence in framing the question and choosing the method than for a bachelor’s thesis. How high the requirements are in detail is set out in the module handbook and the examination regulations.

How do you narrow down a topic?

You narrow a topic by focusing it in four directions: by object of study, time period, region or industry, and perspective. The end result is a research question that you can answer with the available material in the time you have.

An example of the path from topic to question: “Sustainability in companies” is an area and far too broad for a thesis. Narrowed to small and medium-sized companies in the German textile industry, it becomes more tangible. Formulated as a research question, it might read: “Which factors determine whether small and medium-sized textile companies in Germany introduce sustainable supply chain practices?”

• Who is involved? Consumers, companies, authorities?
• What should be studied? A behaviour, a process, an effect?
• Where and when? A sector, a country, a period?
• How? Which connections or mechanisms are at the centre?

A good research question cannot be answered with yes or no, and it asks for more than a mere description. If you notice while narrowing that the literature is sprawling, you are still too broad. If there is hardly any literature, you may be too narrow or too new. The article on literature research (in German) shows how to survey the existing research systematically.

Is the topic feasible?

A topic is feasible if literature, data and time are realistically sufficient. Make this check before you register the topic, because afterwards it is often hard to change. The examination regulations set the rules for this.

• Literature: Search specialist databases and the library catalogue. If you find hardly any hits after one to two hours, the topic is too narrow or too new. If you get hundreds, you need to narrow it further.
• Data: Are there public datasets, or do you have to collect your own? Interviews and surveys need enough participants, and this often takes longer than expected.
• Approvals: You need permission to use company data, and some surveys require approval from an ethics committee. Ask what applies at your university.
• Time: Divide the project into phases (research, data collection, analysis, writing, revision) and estimate each one. Plan a buffer.
• Costs: Software licences, travel or printing costs may arise. Find out whether your chair covers anything.

How do you find a supervisor for the thesis?

Write to lecturers whose research area matches your topic and offer a short conversation during their office hours. Go to the meeting with a one-page outline that shows the topic, research question and planned method.

Your chances are good with lecturers whose courses you have attended and who know you. Some chairs assign topics only after registration or application, while others are open to your own suggestions. Check the chair’s website or ask the secretary’s office.

• Include your degree programme, semester and idea in two to three sentences in your enquiry.
• Ask about expectations during the conversation: How often are there meetings, how quickly is feedback given, which formalities matter?
• Record agreements in writing, for example in an email after the meeting.
• If you receive a refusal, ask whether the person can recommend someone for your field.

How do you write an exposé?

An exposé is a short plan of your thesis in which you record the topic, research question, approach and outline. Many supervisors require it before they agree or before you register. Its length varies by chair, so it is worth asking whether there is a template.

1. Starting point: What is the topic about, and why is it relevant?
2. Research question: One central question, possibly with sub-questions.
3. State of research: Two or three key sources that show you know the field.
4. Method and data: How will you answer the question, and where does the data come from?
5. Provisional outline and timeline: Chapter structure and rough milestones.
6. Bibliography: The sources you have used so far.

Even in the exposé, pay attention to clean citations. The article on avoiding plagiarism (in German) explains how to do this.

How do you find a topic with a company?

A thesis written with a company can give you data, practical relevance and sometimes a foot in the door to working life. You find such topics through job boards for theses, the career pages of companies, your part-time job or an unsolicited application.

Three points matter. First, the thesis still needs academic supervision at your university, which must approve the topic in advance. Second, access to data and contact persons in the company should be agreed in writing. Third, the company may request a confidentiality notice, which means the thesis is not publicly accessible. Clarify before you start what is permitted and how company information will be handled.

Do not let yourself be turned into a contract researcher. The academic research question must be preserved, even if the company has a practical interest.

What happens after you choose a topic?

Once your supervision is confirmed, you register the topic with the examination office. Ask about forms, deadlines and when the processing time starts. After that, the actual writing process begins, which the guide to the bachelor’s thesis (in German) accompanies step by step with a timeline.

If you need help along the way, look at support services such as writing centres, student council advice or tutorials. An overview of support for writing your thesis (in German) helps you find them.

Frequently asked questions

How long should I plan for finding a topic?

Start well before your planned registration, and earlier still if you need a practice partner. Brainstorming, a literature check and a talk with your supervisor take time, especially when lecturers are only available during certain office hours. If you start early, you can check alternatives in case a topic does not work out.

Can I propose my own topic?

Usually yes, if a supervisor accepts it and it fits your degree programme. Some chairs only assign their own topics. Ask the secretary’s office or check the chair’s website to see how this is handled before you invest a lot of time in a proposal.

What if my topic is too broad or too narrow?

If it is too broad, narrow it by time period, region, industry or perspective. If it is too narrow, widen it with a comparison, a second case group or an additional perspective. Discuss the change with your supervisor before you register.

Can I still change the topic after registering?

The examination regulations govern this. A change is often possible only within a short deadline or with the approval of the examination board, and sometimes only by returning the thesis. Ask the examination office beforehand so you know the consequences for deadlines.

What to do now

1. Write down five to ten topic ideas in one sentence each, starting from seminar papers, practice and academic literature.
2. Check the three most promising ideas for literature, data and the time required.
3. Formulate a research question and a one-page exposé for your favourite.
4. Arrange appointments in the office hours of suitable lecturers.
5. Read the examination regulations and registration deadlines before you start.
