🔥 Biography

I am a Postdoc at Nanyang Technological University, working with Prof. Yang Liu. I received my Ph.D. Degree from University of Chinese Academy of Sciences, advised by Professor Xiaochun Cao. My research interests include computer vision, adversarial attack, adversarial training and reinforcement learning etc. At present, I am focused on issues related to the security of large models, including jailbreaking attacks on LLM (Large Language Models), adversarial transferability on VLM (Vision Language Models), and so on.
