Hi! I am Chufan Shi, a PhD student at the University of Southern California since 2025, fortunate to be advised Prof. Xuezhe Ma.
Prior to USC, I earned my master’s degree from Tsinghua University, advised by Prof. Yujiu Yang and bachelor’s degree from University of Electronic Science and Technology of China.
Currently, I am interested in LLM Pre-Training and (M)LLM Post-Training.
Listed are my first and co-first author papers; see my Google Scholar profile for the full list.
