Qing Li

I am an associate researcher at the School of Computing and Artificial Intelligence, Southwest Jiaotong University. Before that, I was a postdoctoral fellow at the School of Software, Tsinghua University. I received my doctoral degree from the School of Informatics, Xiamen University.

My research interests include 3D computer vision and point cloud processing.
