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.
