Hi! My name is Nanjun Zhou. I’m a graduate student from CSE, The Hong Kong University of Science and Technology. Previously, 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, South China University of Technology during my bachelor study.

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 LLM agent, Diffusion Model, Audio and Computer Vision.
