Yunxin Liu
LEAD RESEARCHER
.

I received my Ph.D. in computer science from Shanghai Jiao Tong University in 2011 (through the SJTU-MSRA joint PhD program), M.S. degree in computer science from Tsinghua University in 2001, and B.S. degrees in mechanical engineering and computer science from University of Science and Technology of China in 1998.

I joined Wireless and Networking Group, Microsoft Research Asia (MSRA), in July 2001. My current research interests include mobile systems and networking. I am a member of the IEEE and the ACM.
