Jongmin Lee

I am an assistant professor in the school of Computer Science & Engineering (CSE) at Chung-Ang University (CAU), where I lead the Spatial Intelligence Lab.

I received my Ph.D. degree in Computer Science and Engineering (CSE) at POSTECH, South Korea, where I was a member of the Computer Vision Lab working with Prof. Minsu Cho.

My research interests are detailed here, and recent publications can be found here.
