Hi, I'm
Researcher @ Tencent WXG · Tsinghua University M.S.
I research Large Language Models, Generative Recommendation, and Agentic Reinforcement Learning. Currently at Tencent WeChat Channel (WXG), working on LLM and Agent for live streaming recommendation.
I received my M.S. from Tsinghua Shenzhen International Graduate School, advised by Prof. Kaichen Dong and co-supervised by Prof. Yansong Tang. Prior to that, I obtained my B.E. in Mathematics from Xi'an Jiaotong University.
