I am a Ph.D. candidate at the H. Milton Stewart School of Industrial and Systems Engineering, Georgia Institute of Technology, advised by Prof. Tuo Zhao. I received my bachelor’s and master’s degrees from the University of Science and Technology of China. My research interests include large language models (LLMs), reinforcement learning with human feedback (RLHF), and point processes. My CV could be found here.
