Undergraduate student at the University of Rochester

Zhangyun Tan

I am a senior majoring in Computer Science at the University of Rochester, under the supervision of Prof. Chenliang Xu.

My research focuses on multimodal learning, particularly visual/spatial reasoning and video understanding. Beyond that, I am also working on world models and multi-agent systems.
