Ph.D. Student

Graduate School of AI, KAIST

Hello, I am a Ph.D. student in Language & Knowledge Lab at KAIST Graduate School of AI. I am fortunate to be advised by Minjoon Seo. Before KAIST, I obtained a B.S. in Electrical & Computer Engineering, and Biological Sciences at Seoul National University.

My academic goal is to understand the acquisition and processing of knowledge by intelligent systems from complex patterns. Specifically, my recent focus lies in analyzing language models to understand how they encode, transfer, and utilize knowledge for reasoning and inference. I am open and passionate about studying and integrating concepts from other fields involved in studying intelligence and knowledge (computational neuroscience, complex systems, philosophy, linguistics, psychology, etc.) to deepen my understanding of intelligent systems.
