Jun Ki Lee


I just completed my PhD from the Department of Computer Science at Brown University where I was advised under Prof. Michael L. Littman. My research focuses are in reinforcement learning especially in its explainability, machine learning, robotics, and humand robot interaction (HRI).

Previously, I finished my Master’s in the Media Arts and Sciences at MIT Media Lab. I worked at the Personal Robots Group led by Prof. Cynthia L. Breazeal. I received my Bachelor of Science in Computer Science and Engineering at Seoul National University.
