I am an M.S. student in the OSI Lab at KAIST AI, advised by Prof. Se-Young Yun. My current research focuses on building fast, cost-efficient, and scalable simulation environments for training agents and improving the transfer of learned capabilities from simulation to the real world. I am also interested in AI safety and AI agents.
