About

I am a Ph.D. student at The Hong Kong Polytechnic University, advised by Prof. Qing Li and Prof. Wenqi Fan. I received my B.Eng. in Computer Science and Technology from Harbin Institute of Technology, Shenzhen (HITSZ), advised by Prof. Jing Li.

I am currently a research intern at Tencent Youtu Lab. My research interests lie in Large Language Models (LLMs), Agentic RL, Long Horizon Reasoning, and Post-training.

I have published papers at top-tier venues including ICML and ACL.
