I am a member of the COSEC research group led by Prof. Sheng Zhong. I got my Ph.D. and B.S. degree in Computer Science from Nanjing University. My research interests include but are not limited to the security and privacy of artificial intelligence, networks, and systems.

Our group is recruiting students interested in research on security and privacy preservation. If you have a study plan, please contact us by email.
