Kyungyoon Kim

I am an M.S. student at the Graduate School of Artificial Intelligence, Korea University, where I am a member of the Decision Making Lab (DM-Lab) advised by Prof. Byung-Jun Lee.

My research centers on reinforcement learning and generative models. I am especially interested in the intersection of the two—leveraging generative models to advance reinforcement learning. I am also drawn to robotics as a setting where these methods come together.

Before joining Korea University, I completed the Naver BoostCamp AI Tech program (Computer Vision track) and earned a B.B.A. from Kyung Hee University. Feel free to reach out via email.
