About Me

I am a master's student in Artificial Intelligence at Zhejiang University, expected to graduate in June 2027. I am a member of the Interactive Data Group (IDG) at the State Key Laboratory of CAD&CG, where I am jointly advised by Prof. Yingcai Wu and Prof. Di Weng.

I study long-horizon language agents and recursive self-improvement (RSI), with a focus on AI Business Operations. Drawing on natural language processing, human-computer interaction, and agentic reinforcement learning, I explore how agents learn from feedback to improve their decisions, skills, and tools for autonomous retail operations.
