Hi, welcome to my homepage! I’m a second-year PhD student in Computer Science at the University of California, San Diego, advised by Prof. Prithviraj (Raj) Ammanabrolu at Pearls LabπŸ§‹.

My research focuses on building capable, adaptive, and trustworthy LLM agents that can reason, use tools, collaborate, and improve from experience. I am especially interested in:

Across these directions, I develop methods that help agents:

  • Infer user intent through interaction and translate it into scalable reward and evaluation signals
  • Learn and be evaluated on tasks where success is hard to verify automatically
  • Coordinate in multi-agent settings via reinforcement learning for better human-agent and agent-agent collaboration

I previously interned at Tongyi Lab Logo Alibaba Tongyi Lab with Dr. Liuyi Yao, working on role-play agents and reasoning. Before UCSD, I completed my Master’s in Interdisciplinary Data Science at πŸ’™ Duke University, working with Prof. Brandon T. Fain and Prof. Bruce W. Rogers, and received my Bachelor’s degree from the πŸ‡¦πŸ‡Ί University of Melbourne in Economics and Finance with a minor in Statistics.
