I received a B.A. in Astrophysics and Computer Science in 1995, and my Ph.D. in Computer Science in 2003 from the University of California at Berkeley. Although my dissertation was on novel FPGA architectures, I also was highly interested in Computer Security, including postulating the possibility of very fast computer worms in 2001. In 2003, I joined ICSI, first as a postdoc and then as a staff researcher. My primary research focus is on network security, notably worms, botnets, and other internet-scale attacks, and network measurement. Other areas have included both hardware acceleration and software parallelization of network intrusion detection, defenses for DNS resolvers, and tools for detecting ISP-introduced manipulations of a user's network connection.
