I am a second-year PhD student (2024-2028) at City University of Hong Kong under the supervision of Prof. Dapeng Oliver Wu. I received my Bachelor and Master degrees from Beijing Institute of Technology (2017-2024) under the supervision of Prof. Chi Harold Liu.
I am now working on LLM reasoning, post-training, and deep reinforcement learning. I have published several papers
