I received double B.S. degrees in mechanical engineering and computer science from University of Science and Technology of China, HeFei, Anhui Province, P. R. China, in 1998, and M.S. degree in computer science from Tsinghua University, Beijing, P. R. China, in 2001.

I joined Wireless and Networking Group, Microsoft Research Asia (MSRA), Beijing, P. R. China, in July 2001. My research interests include Computer Networking, System Design and Mobile Computing. I am a member of IEEE.

Since Sep. 2006, I am in the joint Ph.D program of MSRA and Department of Computer Science, Shanghai Jiao Tong University, Shanghai, P. R. China.
