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 and Prof. Jiaheng Wei.

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.
