About

I am a Ph.D. student at ALIN Lab advised by Prof. Jinwoo Shin and Prof. Kimin Lee at Korea Advanced Institute of Science and Technology (KAIST). Previously, I received B.S in Electrical Engineering from KAIST in Feb. 2020. My main research question is to solve challenging decision making problems via RL (e.g., long-horizon tasks, robotic manipulation). Relevant topics include hierarchical RL and representation learning for RL. I am also broadly interested in diverse areas of reinforcement learning, such as goal-conditioned RL, model-based RL, and multi-agent RL. Prior to that, I worked on machine learning for drug discovery.
