Student Theses

We are constantly offering topics for student theses. Most topics can be adapted, no matter if you are looking for a Bachelor's, Master's, or Diploma thesis, or even a research-related module (e.g., INF-PM-FPA). In fact, we highly recommend combining your thesis with a research project or seminar that already works toward your thesis.

If you are interested, please check the remarks below, and make sure to review the formal application requirements and familiarize yourself with the application procedure at the examination office. You are also encouraged to approach a member of our chair. You can contact Florian Tschorsch for an initial consultation, or you can make an appointment with the supervisor of the respective topic directly. It is good practice to get in touch well in advance of your planned starting date.

Requirements and Expectations

We expect that students have substantial knowledge related to privacy and security, typically demonstrated through successful completion of our courses. In addition, candidates for a Master’s thesis should have knowledge in a sub-field related to our research topics and experience with associated research methodologies. Before you start, make sure that you allocate sufficient time for your research work. Our expectation is that you work full time on your thesis project.

The thesis should demonstrate your ability to solve problems independently and document results according to scientific standards. While Bachelor’s theses can be more practical (approx. reflecting the state-of-the-art), Master’s theses should offer new insights (approx. we learn something new). The Bachelor’s thesis can be written in German and English, typically comprising 30-40 pages. The default language for Master's theses is English, typically comprising 60-80 pages.

Supervision

Thesis writing is an interactive process, involving discussions with your supervisor and potentially other members of our research group. Candidates often spend part of the time at our chair. Ideally candidates contribute to our research projects or even publish their results in scientific forums together with us. If you need feedback or assistance, we expect you to take initiative and contact your supervisor.

Research Proposal

Students are expected to draft a research proposal (aka exposé) outlining the motivation, goals, and planned approach, based on discussions with their supervisor. The proposal is a concise description of your work in running text (max. 3 pages excluding bibliography), possibly supported by meaningful tables or figures. The proposal is crucial for making expectations transparent. It basically serves as an agreement on the topic, which aligns all involved parties and minimizes misunderstandings.

As part of writing a research proposal, students are expected to carry out preliminary research to ensure that the chosen topic aligns with their interests and complements their existing skills.

Your research proposal should include the following information:

  • Your understanding of the topic (problem statement)

  • The status quo with references to academic literature (related work)

  • Research question(s) and your planned approach and method

  • Discussion of risks or ethical considerations, if necessary (and how to deal with them)

  • A rough timeline with 2-3 non-trivial milestones

Please note that the above points also suggest a structure for your research proposal. When writing your research proposal, please define the topic as precisely as possible and also specify what is out of scope to manage expectations. Keep in mind that drafting a research proposal is an iterative process involving your supervisor. It may require some time and should already follow an academic style of writing. Your supervisor must accept your final proposal.
