Yu Shang 商宇

I am a researcher at Tongyi Lab, Alibaba Group. Before that, I received my Ph.D. and B.E. degrees in the Department of Electronic Engineering from Tsinghua University, and a second B.E. degree from the School of Economics and Management at Tsinghua University.

My current research focuses on world models and unified multimodal models, with the goal of building intelligent multimodal systems that can integrate perception, reasoning, and action.
