I'm a PhD candidate in the Department of Computer and Science at Tsinghua University. My research interests include human-computer interaction and pervasive interaction. More specifically, I develop novel sensing mechanisms and power schemes to enable better interaction experience in ubiquitous computing environments like smart home.  I'm advised by Prof. Yuanchun Shi at HCI lab.
