About me

Currently, I work as a Research Professor at the Korean Campus of Ghent University, mainly focusing on two areas: (1) image-based self-supervised learning, especially with vision transformers, and (2) explainable AI, frequently applied to biomedical imaging.

Here’s a brief overview of my career, along with my current and past research focus:
