About Me

I'm a final-year Ph.D. student at City University of Hong Kong, co-advised by Dr. Weitao Xu and Dr. Qingchuan Zhao. Previously, I obtained my M.S. degree at Australia National University (ANU), and my B.E. degree at at Shanghai Jiao Tong University (SJTU), advised by Prof. Xinbing Wang.

My research interests include cyber-physical system security, contactless side channels, low-power wireless sensing, and vulnerability discovery (mobile apps, cloud, IoT, VR/AR, and LLMs).

News

Currently, I'm doing my final-year Ph.D. study and looking for postdoctoral or tenure-track faculty opportunities. If you have any suitable positions, please contact me taoni2-c@my.cityu.edu.hk.
