Hi, I'm Ruiming!

I am a Ph.D. student at the Institute of Automation, Chinese Academy of Sciences (CASIA), advised by Prof. Jinqiao Wang. I am also a research intern at Tsinghua AIR, advised by Dr. Xianyuan Zhan. My goal is to build intelligent agents that can perceive, simulate, and interact with the physical world.

Currently, I am working on:

(Generative Models for Decision-Making) Leveraging diffusion and flow-matching models for planning, spanning autonomous driving, embodied manipulation, and RL-based post-training of large models.
(Multimodal Generative Models) Building generative world models that integrate vision, language, action, and 3D structure for practical AI agents.
(Embodied AI) Developing intelligent agents that understand, simulate, and interact with the physical world.

I am always excited to connect with like-minded researchers and explore potential collaborations. Feel free to reach out to me via email or connect with me on GitHub!
