Shuwen Xu
I am currently a final-year undergraduate student at the School of Artificial Intelligence,
University of Chinese Academy of Sciences (UCAS),
advised by Prof. Kang Liu and Prof. Jun Zhao.
In the Spring 2026 semester, I was a visiting student in the Department of Computer Science and Engineering at
The Hong Kong University of Science and Technology (HKUST),
working with Prof. Yi R. (May) Fung.
My research interests include LLMs/MLLMs, agentic reinforcement learning, efficient model training, and embodied AI.
