Seongyun Lee

Ph.D. Student

Hi, I’m Seongyun Lee!

I’m a Ph.D. student at KAIST AI, co-advised by Hyunwoo Kim and Minjoon Seo. I previously received my M.S. in Artificial Intelligence from KAIST AI and my B.S. in Computer Science from Korea University.

My research aims to make evolving AI systems safe and aligned with human values as they face new challenges and risks. I’ve worked on multimodal learning, evaluation, hallucination mitigation, safety, and alignment and these days, I’m especially interested in tackling misalignment issues in agent systems.
