I am a PhD student (full scholarship) in the Department of Computer Science at City University of Hong Kong (CityU), supervised by Prof. Ka-Chun Wong. Prior to this, I received my M.S. degree (Rank 1/232) from the University of Electronic Science and Technology of China (UESTC), and my B.E. degree from Southwest Jiaotong University (SWJTU).

My research interests include Adversarial Machine Learning, AI Security, and Evolutionary Computation, with a focus on adversarial attacks/defenses for DNNs and LLMs, graph model poisoning, and evolutionary optimization.
