About

I’m an M.S. student in the Natural Language Processing (NLP) Group, working with Prof. Gary Geunbae Lee and Prof. Hyounghun Kim at POSTECH. Before joining POSTECH, I completed a B.S. degree in Electrical Engineering at Hanyang University ERICA.

My current research focuses on reasoning agents. In addition, I explore retrieval-augmented generation and question answering.
