Hello! I am a first-year Ph.D. student in Data Science and Analytics at The Hong Kong University of Science and Technology (Guangzhou), advised by Prof. Xinlei He.

My research interests are in AI security & privacy, with a focus on vision segmentation models, LLMs/VLLMs, and image watermarking. In particular, I study backdoor attacks and jailbreaking of modern foundation models, as well as attack/defense for image watermarking systems.

Before that, I received my M.Sc. in Computer Science from City University of Hong Kong and my B.Sc. in Computer Science (Database Systems) from The University of New South Wales.
