Mengfei Li

Bio

I am a PhD student at The Hong Kong University of Science and Technology, advised by Prof. Yike Guo and Prof. Wenhan Luo. My research focuses on real-time interactive video generation and AI games, with interests in action-conditioned video modeling, generative gameplay, and 3D/4D vision. Before that, I received my B.S. in Computer Science and Technology from Sun Yat-Sen University.

Research Interests

Real-time Interactive Video Generation, AI Games, 3D/4D Vision.
