Student Researcher @ Google


CV | Google Scholar | | |


I am a 5th-year PhD student at Yonsei University, advised by professor Seong Jae Hwang in the Medical Imaging & Computer Vision Lab. I am also starting as a Student Researcher at Google (Mountain View, CA Office), working on Efficient Video Representation Learning, hosted by Li Zhang.

I am broadly interested in learning algorithms that bridge visual understanding and multi-modal generative modeling, with a particular focus on label-efficient semantic segmentation, medical-image foundation models and multimodal generation, including image and video generation.
