I'm a Master's student in the School of Computing at KAIST.
I'm working in Collaborative Social Technologies Lab(CSTL) and KAIST Interaction Lab(KIXLAB), where I'm advised by Prof. Joseph Seering and Prof. Juho Kim.
I am interested in Human-AI Interaction and Human-centered AI.
My research aims to support dynamic alignment between humans and AI agents, grounded in mutual understanding and structuring.
I approach this from two complementary directions: (1) from the human's perspective, by building interactive interfaces that help people understand, evaluate, and structure actionable feedback on AI behavior, and (2) from the agent's perspective, by improving its ability to understand user intent and context and to structure what actions to take.
I'm excited to explore how we can design the collaboration betwen humans and AI agents, with interface implementation and data-centric approaches!
