Jisang Han

Graduate Student @ CVLAB, KAIST AI

Hi, I'm Jisang Han 👋

I am a Ph.D student at KAIST AI advised by Seungryong Kim. Currently a Student Researcher at Google DeepMind. Prior to that, I spent a wonderful summer at AI4CE Lab, NYU. I am also closely collaborating with Sony AI, Tokyo.

My research interests lie in the intersection of computer vision and machine learning, particularly in 3D computer vision and robot learning. My goal is to solve fundamental problems in 3D computer vision and apply them to real-world scenarios.
