Hi! I am Haoyang, a M.Sc. student in Computer Science and research assistant at TASR-Lab@HKU supervised by Prof. Ka-Ho Chow. Before that, I was a visiting student at PR-Lab@NJU under the supervision of Prof. Yueming Lyu and Dr. Yi Liu. I obtained my B.Eng. degree at School of Cyber Science and Engineering, Nanjing University of Science and Technology (NJUST) adviced by Prof. Zhichao Lian and Dr. Shuangquan Zhang. In addition, I had a wonderful time at Tencent exploring AI governance, security, and privacy.
My research interests mainly focus on the security and privacy of trustworthy large models, including jailbreaking, poisoning, member inference, data extraction (…) attacks and developing effective defenses to secure LLM, RAG, Agent systems, etc.
