Projects for final theses (Bachelor/ Master)

You will find more detailed information on the theses offered under the topics listed below. The contact persons for the respective theses are also listed there. Please apply directly to the contact persons!

If you do not find any information about the respective contact person, you are welcome to contact our secretariat susanne.warth∂ or beate.skolik∂ - your request will then be forwarded internally. Please let us know in your mail which topic you are interested in and in which time frame you plan to do the work. We will get back to you as soon as possible if a suitable topic can be offered for you.

BIW or CIW students can find the registration requirements and more detailed information on the Bachelor's thesis (please scroll down) and the Master's thesis here. The thesis must be registered no later than four weeks after it is started. Here you can find a schedule.

Biologists please register at the examination office before starting the bachelor thesis. The registration conditions and the registration link can be found here and for the master thesis here. For registration please print out the pdf-file and send it together with a current grade transcript to Simone Lepoutre (building 30.43; room 003).

Currently, we offer the following topics, among others:
