I am an undergraduate student at Sun Yat-sen University, majoring in Intelligent Science and Technology. My research focuses on video generation, world models, and multimodal spatiotemporal understanding. My research began with graph learning and has grown toward video and 4D scenes. I am particularly interested in how models represent objects, maintain their states over time, and use generation to understand and interact with the world. I collaborate with researchers at HKUST, Shanghai Jiao Tong University, and Westlake University on video generation and embodied intelligence. I am also part of InkMind.AI, where we explore multimodal understanding and generation, along with tools and workflows for AI-assisted research. I welcome research collaborations in generative modeling and embodied intelligence. Feel free to contact me.
