I am a Ph.D. student at the School of Computer Science, Peking University, advised by Prof. Boxin Shi. I am currently working closely with Shuchen Weng at the Beijing Academy of Artificial Intelligence (BAAI). I received my B.S. degree from the Turing Class at Peking University in 2025.

My research interests include world models, embodied intelligence, video generation, and computational photography. I am currently an intern at XLab, AI² Robotics.

Previously, I worked with Prof. Tianfan Xue at Shanghai AI Laboratory and Prof. Hao Dong at the Center on Frontiers of Computing Studies, Peking University.

I am looking forward to internship and collaboration opportunities, especially in world models and embodied intelligence. Feel free to get in touch!
