I received my M.S. degree in Computer Technology and B.E. degree in Computer Science and Technology from Xi’an Jiaotong University in 2016 and 2013. Now I am a Ph.D. candidate at Peking University and supervised by Prof. Daqing Zhang. My research interests include ubiquitous computing and wireless sensing.
