About Me

Hello! This is Huishuai Zhang. I am an assistant professor at Wangxuan Institute of Computer Technology, Peking University starting from Jan. 2024. Before joining academia, I was a Principal Researcher at Microsoft Research Asia. Before that, I have spent 5 years in Syracuse University, 3 years in Chinese Academy of Sciences and 4 years in University of Science and Technology of China (USTC). My research work aims at large language models, differential private machine learning and optimization.
