Chaehyun Kim

I am an integrated M.S./Ph.D. student of KAIST CVLAB under Prof. Seungryong Kim and a research intern at Naver Cloud, with a focus on generative world modeling.

My research interests lie at the intersection of computer vision and embodied agents, focusing on developing semantically rich perception and generative models to advance robot perception and world modeling.

If you have any questions or suggestions, please feel free to contact me via email (kchyun@kaist.ac.kr) or LinkedIn!
