Sunset at Dongtai Jinel Lake, Qinghai, China

I am a master's student in Statistics at the University of Wisconsin–Madison, where I am fortunate to be advised by Prof. Xiao Luo. I am currently collaborating with Prof. Yu Zhang at Texas A&M University and Prof. Muhao Chen at UC Davis. I have also collaborated with Prof. Yizhou Sun and Prof. Wei Wang at UCLA. I received my bachelor's degree in Mathematics from Wuhan University.

My research focuses on LLM agents, Agentic LLM Post-training, and AI for Science. I am interested in developing efficient and auditable agentic systems for complex research workflows.

              Outside of research, I enjoy playing tennis 🎾 and watching soccer ⚽, and my favorite player is Kylian Mbappé 🥷🐢.
              This semester, I'm also an intramural soccer referee at UW–Madison.
