AI agents are joining human society. I build better social agents by and how they navigate our social world, and them into social and user simulations that help people make better decisions.
EvaluateI build benchmarks and evaluation methods that reveal where AI agents fall short in social settings: whether they cooperate and reason well together, hold implicit biases, and stay loyal to the people they serve.

ImproveI develop agent harnesses and post-training methods that fix these failures, making agents more robust and more faithful to the people they serve.

IntegrateI build social and user simulations with LLM agents, along with the methods and interfaces to validate, steer, and oversee them, so people can test decisions before making them in the real world.

I’m a third-year PhD student in the Human-Computer Interaction Institute at Carnegie Mellon University, where I’m advised by Hirokazu Shirado and Sauvik Das. Before CMU, I received my BS in Computer Science from
Tsinghua University in 2024. I’ve spent time as a research intern at Microsoft Research AI Frontiers,
Microsoft AI, and UC Berkeley. My first-author work has appeared at both AI and HCI venues, including ICML, EMNLP, UIST, and FAccT, and has been . I’ve also enjoyed sharing my work through invited talks at places like CMU, Georgia Tech, Tsinghua, KAIST, HKU, and Microsoft.
