Short CV

Since November 2021, I am a researcher at the Chair of Communication and Distributed Systems. Before, I graduated with an M.Sc. in Computer Science at RWTH Aachen University. I am part of the Security and Privacy Group, and my research centers around privacy-preserving methods such as confidential computing, homomorphic encryption, and trusted execution environments.

Looking for a Thesis?

Great! I always seek motivated students interested in improving privacy-preserving methods in today's distributed systems and analyzing their security. Email me two sentences on your motivation and research interests. Also, include a recent transcript of records or another reference, and we might figure out a suitable thesis topic together.

Due to high demand, I typically hand out a quick introductory challenge before starting a new thesis. Prepare for about one week of preliminary work before starting to work on your thesis.
