Hi! I’m a final year undergraduate student from Department of CSE, South China University of Technology, majoring in Computer Science and Technology. I am honored to be supervised by Prof. Li Liu from AI Thrust, HKUST (Guangzhou) and Prof. Tong Zhang from DSAIL, South China University of Technology. I’m about to join HKUST as a M.Sc student in fall 2025.

My current research interest focuses on Trustworthy Machine Learning, particularly on Backdoor Learning. I’m interested in security issues across all domains of AI, including Computer Vision, Audio & Signal Processing and Large Language Models.
