Yuming Li

I am a PhD student at the University of Hong Kong, affiliated with the Musketeers Foundation Institute of Data Science, where I am advised by Andrew Luo.

I received my Master's degree in Software Engineering from Peking University, where I worked with Shanghang Zhang. Before that, I earned my Bachelor's degree in Computer Science and Technology from Northwestern Polytechnical University.

My research focuses on real-time long video generation, reinforcement learning alignment for diffusion and video generation models, controllable multimodal generation, and embodied world modeling. I am interested in building generative video systems that are fast, controllable, and temporally consistent.

Research

I work on generative video systems for long-horizon, controllable, and real-time generation. My recent work studies structured RL post-training for diffusion models, streaming audio-visual generation, fast video initialization, and multimodal world models.
