  About Me
I'm currently a Software Engineer in the Platforms Group of Google, in Mountain View, working on next generation of the super cluster in Google using Software Defined Networking (SDN) technology.

Previously, I was a Ph.D. student in Computer Science and Engineering at the University of Michigan, Ann Arbor. I work with Professor Z. Morley Mao. My research interests include smartphone related research topics, such as the performance and power related research for 3G/4G networks. I'm also interested in designing and implementing systems that give smartphone users better experiences.

I got my B.S. in Computer Science from Tsinghua University, Beijing, China in 2008. In 2006, I'm selected to be a member of Special Pivot Yao Class supervised by Turing Award winner, Prof. Andrew Chi-Chih Yao (only 24 of all undergraduate students at Tsinghua University selected).

I interned in Microsoft Research Asia in 2007, Microsoft Research Silicon Valley in 2010 and AT&T Labs - Research in 2012.
