Anson Tsun On Kwok

I am a first-year MPhil student in the Department of Computer Science and Engineering at The Hong Kong University of Science and Technology, supervised by Prof. Yangqiu Song. Previously, I earned my B.Sc. in Computer Science from The Chinese University of Hong Kong.

My research interests lie in the security and trustworthiness of large language models and their applications. I am currently working on developing watermarking frameworks for agent memory and mitigating context-aware adversarial vulnerabilities.
