Biography

I am a researcher in Shanghai AI Laboratory. I obtained my Ph.D degree from THUNLP Lab, Dept. of Computer Science and Technology, Tsinghua University, advised by Prof. Zhiyuan Liu. Before that, I obtained my B.S. degree of Mathematics and Physics, Tsinghua University in 2019.

My research interests lie at LLM alignment and reinforcement learning. Previously, I did some research on representation learning on graphs, especially graph neural networks and their application.

We are hiring! If you are interested in building large reasoning models with reinforcement learning, please drop me an email (thu.cgq AT foxmail.com).
