I am a PhD candidate in the Computer Science Department of University of California, Los Angeles, supervised by Prof. Songwu Lu. Prior to joining UCLA in Sep 2009, I had worked as an associate researcher in the Wireless and Networking Group at Microsoft Research Asia (MSRA). I got my B.E and M.E (both with greatest honors) in 2002 and 2005, respectively, both from Automation Department of Tsinghua University in China.
My research interests include mobile systems, wireless networking, cloud computing and network security.
