Biography

Since Januar 2023, I work as an Engagement Manager for Akamai. Before, I was a researcher at the Chair of Communication and Distributed Systems at RWTH Aachen University. As a member of the Network Architectures group, my research was mainly focused on network protocols, their real-world deployment, the resulting performance implications, and optimization.
