Kimin Lee
I'm a research scientist at Google Research. Previously, I was a postdoc at UC Berkeley (advised by Pieter Abbeel), and I received my PhD at Korea Advanced Institute of Science and Technology (advised by Jinwoo Shin). During PhD, I also interned and collaborated closely with Honglak Lee at University of Michigan.
