About me

Hi! My name is Nanjun Zhou. I’m 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, particularly on Backdoor Learning. Currently, I focus on the trustworthiness of LLM agent. I’m also interested in security issues in other domains of AI, including Diffusion Model, Audio and Computer Vision.
