Biography

• I belong to the Ubiquitous System Security Lab (USSLAB) and work with Prof. Wenyuan Xu. I joined the Department of Electrical Engineering at Zhejiang University as an assistant professor in 2016.

• I work on IoT Security, including sensor/sensing security, AI security, and smart-grid security. Especially I am now interested in sensor-oriented security, including sensor measurement security, sensor-induced AI security, as well as sensor-oriented protections such as privacy enhancement.
