Minjae Oh

I am a Ph.D. student in Data Science at Seoul National University, advised by Prof. Yohan Jo in the Human-Oriented Language Intelligence (HOLI) Lab. My research centers on reinforcement learning and reasoning with large language models. Recently, I have been looking into physical AI and world models with reasoning.
