Bio

I am now an Assistant Professor (Tenure-Track) at Department of Computer Science and Technology, Peking University. Before joining PKU, I worked at Institute of Computing Technology, Chinese Academy of Sciences (ICT-CAS) from Septemper 2017 to May 2020, and at Huawei Future Network Theory Lab (based in Hong Kong) from September 2015 to September 2017. I got my Ph.D. degree in August 2015 in Department of Computer Science and Engineering, The Chinese University of Hong Kong, advised by Professor Patrick P. C. Lee. I received my bachelor degree in Computer Science from Peking University in 2011.
Research interests:
My research mainly focuses on distributed stream processing and network measurement. I'm also interested in areas including distributed systems, computer networks, operating systems, cloud computing, randomized algorithms and machine learning.
