About
I am an AI Researcher at the Language Intelligence Lab, ETRI. I received my M.S. in Artificial Intelligence from Konkuk University, advised by Prof. Harksoo Kim, and my B.E. in Civil & Environmental Engineering from the same university. My research concerns the fundamental decision-making of large language models and the factors that shape it, such as emotion and culture, as well as the use of LLMs as agents in domains like code and science.
