Biography

I am a researcher and Ph.D. Student at Klaus Wehrle’s Chair of Communication and Distributed Systems at RWTH Aachen University. My research interests focus on but are not limited to the optimization of modern network protocols such as QUIC and HTTP/3. This research involves analyzing the current use and adoption of these protocols via Internet measurements, their current performance and how to develop novel mechanisms to optimize this performance in the long run.
