About

Hello! I am a Researcher at the Language Intelligence Lab, ETRI, where I work on autonomous agents. I obtained my M.S. in Artificial Intelligence at Konkuk University, advised by Prof. Harksoo Kim, after a B.E. in Civil & Environmental Engineering at the same university.

My research is on making autonomous systems verifiable: code generation checked by running it, research agents that keep results traceable to their sources, and evaluation methods for LLM tutoring and multilingual dialogue. The common thread is that a model cannot certify its own output, so I build the part that can.
