About Me

I’m Tianyuan (Roger) Dai, a Master’s student in Computer Science at Stanford University, affiliated with the Stanford Vision and Learning Lab. I have the privilege of conducting cutting-edge research in embodied AI and robotic learning, advised by Prof. Fei-Fei Li. Previously, I obtained a Bachelor’s degree in Computer Science and Mathematics at the Hong Kong University of Science and Technology (HKUST), where I worked on 3D and multimodal generation, advised by Prof. Chi-Keung TANG and Prof. Yu-Wing Tai.

Special thanks to Prof. Hao Su, whose talk at HKUST in my final undergraduate semester inspired me to transition from computer vision to embodied AI. I am also deeply grateful to Josiah Wong, Yunfan Jiang, Chen Wang, and Ruohan Zhang for their invaluable advice on both research and life.
