I am currently a Senior Researcher at Tencent Media Lab.

Before I join Tencent,  I got my PhD degrees in Department of Computer Science and Technology, Tsinghua University, under supervision of Prof. Yong Cui. I was visting School of Electrical and Computer Engineering, Purdue University, during September 2016 to October 2017, under advisor Prof. Y. Charlie Hu. My research interests include mobile systems/networks, cloud computing and cloud storage. I received my B.E. in 2013 in Department of Computer Science and Technology, University of Electronic Science and Technology of China.
