About

I am a PhD student at KAIST (MLAI Lab), working under the supervision of Sung Ju Hwang.

My research focuses on computer vision and deep learning, particularly generative tasks using multimodal foundation models like text-to-video models. Currently, I’m interested video generative models and the applications of generative foundation models toward complex capabilities like world modeling as physical simulator and world action models (WAM).
