I am a research associate at the CMAND lab at the Naval Postgraduate School in Monterey, California. Prior to that, I was a PhD student and postdoc at the Internet Network Architectures (INET) group, Technische Universität Berlin.
My research centers around data driven analyses of the Internet: topology, routing and traffic.
