Integrated M.S./Ph.D. Student in Electrical and Electronic Engineering at Yonsei University, working on computer vision and machine/deep learning for video.
My research centers on scene understanding and vision-language multimodal learning, including video temporal grounding, video scene graph generation, and video large language models. I am interested in building models that reason about motion, long-range temporal structure, and language for real-world video understanding.
About
I am an Integrated M.S./Ph.D. student in Electrical and Electronic Engineering at Yonsei University, in the Image and Video Pattern Recognition Lab (MVP Lab), advised by Prof. Sangyoun Lee. I received my B.S. in Electrical and Electronic Engineering from Korea University.
My research lies in computer vision and machine/deep learning, with a focus on scene understanding, video temporal grounding, and video scene graph generation, as well as vision-language multimodal learning for video large language models.
I am interested in models that can understand dynamic visual content, reason about motion and long-range temporal structure, and connect vision with language for robust real-world video understanding.
