Juyong Lee


I am a PhD(/MS int.) candidate at KAIST, advised by Kimin Lee. I received a B.S. degree with a double major in both mathematics and computer science/engineering at POSTECH. I have an experience as an exchange student at Stanford.

My recent study focuses on building autonomous agents with LLM and RL for digital device control.
