Bio

I am currently a Ph.D. candidate at Beihang University, where my research focuses on Deep Reinforcement Learning and Large Language Models. I am fortunate to be advised by Prof. Si Liu. I received my Bachelor's degree from Beihang University in 2021. Currently, I am also a research intern at Tencent, working under the guidance of Zhongwen Xu.
