I am an incoming Ph.D. student at UC San Diego HDSI, advised by Prof. Hao Zhang.

I am a Software Engineering Intern at Google, starting June 15, 2026.

I work on agentic inference and reinforcement learning for language models.

About

My work focuses on building useful AI agents and scalable systems for LLM reinforcement learning, especially rollout infrastructure, digital environments, and agent evaluation.

Previously, I received my B.S. in Data Science from UC San Diego and worked with Prof. Hao Zhang and Prof. Haojian Jin on AI agents and LLM reinforcement learning.
