Yongjian Fu「付永健」

I am a Ph.D. candidate in the CSE department at the Central South University, advised by Prof. Yaoxue Zhang and Prof. Ju Ren. Prior to that, I received my bachelor degree from Central South University in 2021. I worked closely with Prof. Lili Qiu at MSRA from 2023 to 2024, and with Prof. Xinyu Zhang at UCSD as a visiting scholar from 2024 to 2025.
