University of Science and Technology of China (中国科学技术大学)
I am a tenure-track professor at the School of Cyber Science and Technology, University of Science and Technology of China. My research interests include digital watermarking, AI security and AI-agent security. My current research focuses on multimedia watermarking and agent security. Prior to joining USTC, I was a postdoctoral researcher at National University of Singapore, working with Assoc. Prof. Chang Ee-Chien. I obtained my Ph.D. (2021) from USTC under the supervision of Prof. Yu Nenghai and Prof. Zhang Weiming.
