About

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

I build AI that can be trusted to write software and run research on its own. The trust comes from checking its work against the world instead of its own reasoning. That makes it a partner you can delegate to rather than a tool you have to watch.
