Qinghua Liu

I am a researcher at OpenAI, working on posttraining for ChatGPT.

I received my Ph.D. from Princeton, advised by Chi Jin. My PhD research focused on fundamental theories in reinforcement learning (RL), including partially observable RL (POMDP, PSR, Survey), multi-agent RL (Stochastic Game), and RL with large state spaces (Function Approximation). After that, I spent a wonderful year as a postdoctoral researcher at Microsoft Research NYC, where I explored language model research.

During summer 2022, I interned at DeepMind, working with Csaba Szepesvári and Gellért Weisz. Previously, I received a B.E. degree in Electrical Engineering and a B.S. degree in Mathematics from Tsinghua University.
