I am a fifth-year PhD student in Computer Science at University of Wisconsin-Madison, where I am fortunate to be advised by Frederic Sala. Before that, I was a master’s student at Seoul National University, where I was lucky to learn deep learning, exploratory data analysis, and information theory from Wonjong Rhee. Prior to that, I received B.A in Psychology and B.S. in Computer Science and Engineering from Seoul National University.

My research focuses on data-centric AI, with an emphasis on programmatic weak supervision and weak-to-strong generalization in foundation models. Additionally, I am developing techniques that enable zero-shot adaptation of foundation models without fine-tuning, addressing challenges related to data distribution shifts.
