I am a Principal Research Scientist at Microsoft's Office of Applied Research.
Before Microsoft I was a scientist at Airbnb working on ML and NLP problems.
I obtained my Ph.D. at University of California, San Diego
(UCSD), advised by Prof. Julian McAuley. Before
that, I received my master's degree in Statistics
from University of Illinois at Urbana-Champaign, and my undergraduate degree in Statistics from Peking University. I was also a student from the
liberal arts college program (Yuanpei
Program) at Peking University.
My current research focuses on LLM-Based Human-AI Interactive Systems.
Technical topics I'm interested in include LLM Alignment, Complex Reasoning and Planning, LLM Orchestration and Routing, User Simulation, LLM Agents and Agentic Systems.
We are hiring both 2025 spring and summer research interns, FTE researchers and postdocs at Office of Applied Research. Feel free to send me an email if you're interested.
