👨‍🎓 About Me

I am a third-year Ph.D. student at Peking University, advised by Prof. Xuejun Yang and Prof. Wenjing Yang. I earned my B.S. degree at China University of Geosciences in 2023. Prior to that, I served for two years in the People’s Liberation Army.

My primary research interest focus on Foundation Models for Multimodal Learning. I am also interested in Causal Inference and Reinforcement Learning. My overarching research goal is to build reliable and generalizable multimodal intelligence, with a focus on developing principled methods that integrate vision, language, and structured reasoning under real-world conditions.

Currently I am working on Efficient Pretraining and Fine-tuning of Multimodal Large Language Models.

I am actively seeking research discussions and collaboration opportunities, so feel free to contact me! 😄
