Trustworthy AI / LLM Agent

I am an Applied Scientist at AWS Applied AI Solution, where I build and evaluate production-ready AI agents for customers. My ongoing research interests span statistical learning in LLMs, including its applications in machine unlearning and bias mitigation, and also LLM agent optimization through recursive self-improvement and agentic reinforcement learning.

Previously I was a member of Cognitive AI Lab (CAIR) at the University of Minnesota-Twin Cities, where I was honored to be advised by Prof. Serguei Pakhomov. Before that I graduated my bachelor degree from Zhejiang University in 2017 and received my M.S. from Duke University in 2019.
