About

Hi, there! I’m Yifei, a second-year Ph.D. student affiliated with Berkeley AI Research (BAIR). I’m advised by prof. Sergey Levine.

These days, I am most interested in interactive decision-making/reinforcement learning with LLM/VLMs (i.e. LLM/VLM agent). In particular, I am interested in large-scale self-improvement where the agent improves itself through open-ended reinforcement learning without any human supervision.

I graduated from Cornell as an undergrad where I have am fortunate enough to have been working with prof. Yansong Feng at Peking University, prof. Wen Sun at Cornell University, and prof. Sernam Lim at Meta AI.
