Yoonseok Choi
I'm a third-year Ph.D. student at the Yonsei University Medical Imaging AI Lab (MILAB) advised by Prof. Dong-Hyun Kim. Also, I'm researching in Vision & Learning Lab (VLLab) at UC Merced, supervised by Prof. Ming-Hsuan Yang during 2025 as a visiting scholar. My research interests include medical image analysis, computer vision. Specifically, I have an interest in developing deep learning techniques to address clinical unmet needs, particularly in solving the missing modality issue.
I am always open to collaboration with like-minded individuals. If you are interested in working together or discussing ideas, please feel free to reach out to me via email anytime!
