About

I am a Ph.D. student in the School of Computing at KAIST. I work with Juho Kim as a member of KIXLAB.

My research interest lies in the intersection of human-computer interaction (HCI) and natural language processing (NLP). I aim to support people to learn from and make sense of dense information (e.g., content in lecture videos, scientific articles) by creating diverse scaffoldings (e.g., QAs, dialogues, explanations) using AI models. Recently, I have been interested in generating outputs that align with diverse human characteristics and evaluating how well this alignment is performed.
