Looking for a thesis?

I always seek motivated students doing a bachelor’s or master’s thesis at COMSYS. If you are interested in privacy-preserving methods or the security of distributed systems, we should get in touch! You can expect cutting-edge research topics, extensive supervision and regular feedback. Usually, I also invite motivated students to co-author follow-up paper projects.

Still unsure or trying to figure out a good idea? No problem! Email me two sentences on your motivation and general research interests. Also include a recent transcript of records or another reference and we might find a suitable thesis topic together.
