I am a second-year Ph.D. student at [Stanford CS](https://www.cs.stanford.edu/), advised by Professor [James Zou](https://www.james-zou.com/) and [Stefano Ermon](https://cs.stanford.edu/~ermon/). Before that, I received my B.S. in Math and Computer Science at Yuanpei College, [Peking University](https://english.pku.edu.cn/), under the advice of Professor [Liwei Wang](http://www.liweiwang-pku.com/) and [Di He](https://dihe-pku.github.io/).

- (Nov. 2025) We released NVIDIA [Cosmos-Predict2.5](https://research.nvidia.com/labs/dir/cosmos-predict2.5/), the Cosmos World Foundation Models specialized for video generation. I am responsible for designing the RL algorithm and performing large-scale post-training (1K+ GPUs) for the release. The algorithm paper will be publicized soon.
