I am a first-year M.S. student in the Graduate School of Artificial Intelligence at Pohang University of Science and Technology (POSTECH), advised by Prof. Sangwoo Mo.

My research interests lie in Physical AI, including Vision-Language-Action (VLA) models and multi-agent systems. I am interested in developing embodied agents capable of generalizing to unseen tasks and collaborating effectively to solve complex tasks.
