I am now an Associate Professor at Research Center for Advanced Computer System (ACS), Institute of Computing Technology, Chinese Academy of Sciences (ICT-CAS). I got my Ph.D. degree in January 2016 in Institute of Software, Chinese Academy of Sciences, advised by Prof. Tao Huang. I received my bachelor degree in Computer Science from University of Sciences and Technology of China in 2009.
Research interests:
My research research interests include operating systems, distributed systems, cloud computing and now with a focus on software defined cloud computing.


I am recruiting self-motivated interns (Ph.D., M.S. or undergraduate students) to work with me on cloud computing, distributed systems and performance models. Please send me an email with your resume if you are interested.
