Hello! I am a first-year Ph.D. student at Seoul National University, advised by Prof. Gunhee Kim. Before that, I received my B.S. in CSE from POSTECH in 2025.

My long-term ambition is to contribute to solving problems that are genuinely important for the future of humanity. During my Ph.D., I aim to build an independent mental framework by learning A. how to identify important problems, B. how to solve them effectively, and C. how to clearly communicate and justify my solutions to others.

I am particularly focused on methods for enabling language models to tackle difficult problems by leveraging textual, non-parametric knowledge—currently through research on AgenticRAG. Looking ahead, my interests include: 1) utilizing additional forms of knowledge beyond text (e.g., multimodal or experience), 2) improving LMs to address challenging known-unknowns (e.g., scientific reasoning problems)

Beyond research, I love discussions on a wide range of topics and exchanging diverse perspectives. If you’d like to connect, please feel free to book a 30-minute conversation through my calendar.
