I am a Ph.D. student at Zhejiang University, and a member of USSLab (Ubiquitous System Security Laboratory) led by Prof. Wenyuan Xu. I received my B.S. degree in Electrical Engineering from Zhejiang University, Hangzhou, China, in 2016. My research interests include network security, IoT security, mobile & ubiquitous computing, and human computer interaction.
