About Me

I am a Second-year PhD student at The Chinese University of Hong Kong (CUHK) supervised by Prof. Pheng-Ann Heng and Prof. Chi-Wing Fu. My research interest lies in building a robotic foundation model that realizes an intelligent robot architecture with the capabilities to ‘Understand, Think, and Act’. Therefore, my current research directions mainly include Vision-Language-Action Models, World-Action Models, and Multi-Modal Learning. Feel free to reach out - I’m always open to discussions and potential collaborations! 😄
