Hi there Welcome to my Homepage!

I am a fourth-year undergraduate student at Tianjin University of Technology, advised by Prof. Jianhua Zhang and Prof. Xu Cheng. I will pursue my M.S. degree at the Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS), with research training at the Institute of AI for Industry (IAII), under the supervision of Prof. Chunhe Song. I am also involved in research on world models and embodied intelligence with Prof. Kai Xu at IAII, and work as a research assistant with Prof. Hao Tang at Peking University.

🎯 My research interests include world models, embodied AI, and reinforcement learning. My long-term goal is to build generalizable world models for robotic agents, enabling them to better understand, predict, and interact with the physical world, and ultimately serve humans in real-world scenarios.
