CS PhD @ Princeton

Hello! I am an incoming Ph.D. student in Computer Science at Princeton University, advised by Prof. Danqi Chen. Prior to that, I received B.S. in CSE from Seoul National University, where I was fortunate to be working with Prof. Eunsol Choi.

My research focuses on NLP, where I am interested in making large language models better utilize dynamic information and acquire meaningful knowledge. Current areas of interest include retrieval-augmented generation, multi-turn interactions, and web agents.
