I am doctoral student in computer science at UC Berkeley, where I have the good fortune of being advised by Vern Paxson. I also have an office at the International Computer Science Institute (ICSI), where I collaborate with folks from the networking group. Before moving to California, I received a B.S. and M.S. from the Technische Universität München.
My research interests primarily cover large-scale network intrusion detection and high-performance traffic analysis. Most of my current work focuses on network forensics in conjunction with the Bro network security monitor.
