I am now a Researcher at Biomedical Artificial Intelligence Research Unit, Institute of Innovative Research, Tokyo Institute of Technology, hosted by
Prof. Kenji Suzuki. I got my Ph.D. degree from Graduate School of Information Science and Technology, Hokkaido University in March 2023, supervised by
Prof. Masayuki Ikebe.
My main interests are in Medical Image Analysis, Multi-modal, Explainable AI, and Computer Vision.
