I joined the Computer Science Department at the Univeristy of Arizona in 2005. I
received my PhD from UCLA in 2003, and BS from Peking University, China in
1995. Before coming to Arizona, I spent two years as a postdoc at USC/ISI-East
and UCLA.
Research
My research area is computer networks and I'm interested in large-scale
networked systems in general. I have been working on Internet routing
architecture and protocols, Internet topology, routing security, multicast and
overlay networks.
