About
I am a master student from The Hong Kong University of Science and Technology. I earned my bachelor degree from School of Computer Science & Engineering, South China University of Technology, majoring in Computer Science. I was honored to be supervised by Prof. Li Liu from AI Thrust, HKUST (Guangzhou) and Prof. Tong Zhang from DSAIL, SCUT during my bachelor study.
My research interest lies on Trustworthy Machine Learning. Currently, I focus on the security of LLM agent, including Prompt Injection and Backdoor Learning. I'm also interested in security issues in other domains of AI, including Diffusion Model, Audio and Computer Vision.
