About

I am a Researcher at the Language Intelligence Lab, ETRI, working on autonomous agents. I obtained my M.S. in Artificial Intelligence at Konkuk University, advised by Prof. Harksoo Kim.

I build AI that can be trusted to act on its own, whether it is writing software or running research. For me that trust comes from grounding: a system that checks its work against the world, rather than against its own reasoning, is one you can actually leave running.
