Kimin Lee

I am an assistant professor at the Graduate School of AI at KAIST. Before joining KAIST, I was a research scientist at Google Research. I completed my postdoctoral training at UC Berkeley (working with Pieter Abbeel) and PhD at KAIST (advised by Jinwoo Shin). During PhD, I also interned and collaborated closely with Honglak Lee at University of Michigan.
