Hi, I am a Ph.D. student in Industrial and Systems Engineering at KAIST, advised by Dabeen Lee. I received my B.S. in Electrical Engineering and Computer Science from GIST, with a minor in Mathematics.
My research focuses on safe reinforcement learning (RL) and sequential decision-making under constraints. I develop algorithms that learn to make effective decisions while respecting safety and resource constraints, with provable guarantees in challenging settings such as adversarial and non-stationary environments, function approximation, and infinite-horizon problems. I am also broadly interested in bandits, online learning, and their real-world applications.
