PhD Student in Artificial Intelligence

I am a first-year PhD student at Peking University. My advisor is Prof. Chi Zhang (张驰). My research focuses on generative evaluation and agentic reasoning in open-ended and dynamically generated environments.

My academic journey began at age 15 in the Wu Jianxiong Honor College at Southeast University, followed by a Master’s from UCAS, where I served as Student Union President. Prior to returning to academia, I spent four years as a Deep Learning Researcher at Baidu’s Autonomous Driving Department, leading the development of retrieval-based planning and self-supervised frameworks.

My recent work develops generative and augmented evaluation frameworks for frontier AI systems, including UniCode (ICML 2026) for code reasoning and MCU (ICML 2025 Spotlight) for open-ended game agents.
