Yuchen Yang

彼一如我 ——木心

Hello!

My name is Yuchen Yang or you can call me Charles, Charrrrrlie (with a long drawl, as the unique site).

I am currently a Ph.D. candidate of Fudan University and Shanghai AI Laboratory in a co-supervised project, under the supervision of Xiao Sun, Yu Qiao, and Xiaoou Tang. During my Ph.D., I had the honor of working with Zhihang Zhong and Xing Gao, who provided invaluable guidance and support.

Before that, I obtained my Bachelor’s degree at Wuhan University, supervised by ZhenZhong Chen.

My research interests lie in: Human-Centric Scene Perception and Understanding
Especially: Spatial Intelligence of VLMs, Human Pose and Motion, and Sports Understanding.
~~Previously: 3D Perception in Autonomous Driving.~~
