Principal Research Manager

About

Yunxin Liu is currently a Principal Researcher and the research manager of Heterogeneous and Extreme Computing (HEX) group at Microsoft Research Asia (MSRA). He joined MSRA in July 2001 and worked in Wireless and Networking (W&N) group, Mobile and Sensing System (MASS) group, and Intelligent Cloud and Edge (ICE) group, before joining HEX group. He received his 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, respectively.

He has broad research interests on mobile computing and edge computing, including power management, security and privacy, sensing, and intelligent edge/mobile systems. His work has been published in top conferences and journals such as MobiSys, MobiCom, NSDI, CCS, TON, TMC, and TPDS; shipped into MS products such as Visual Studio, XBOX XDK, and Windows Phone; and featured in news media including ABC News, The Register, NetworkWorld, and many others. He served as a TPC member of a set of conferences such as MobiSys, WWW and INFOCOM. He received MobiCom 2015 Best Demo Award, PhoneSense 2011 Best Paper Award, and SenSys 2018 Best Paper Runner-up Award. He is a senior member of the IEEE and a member of the ACM.
