I'm an integrated M.S.–Ph.D. student in Data Science at Seoul National University, advised by Yohan Jo in the HOLI Lab.
AI agents can already solve many real-world problems. I believe making them better takes more than improving task performance: we also need to understand how they behave, what guides their decisions, and how they respond to people. My long-term goal is to build agents that understand people and act in line with their goals and values.
