Ryusuke Nakai   |  Senior Lecturer  |  Biomedical Engineering / Biological Information Engineering

My research investigates and develops methods of image acquisition, image analysis, and biological simulation to analyze the functions of biotissue (brain, nerve, muscle, joint, etc.) with more precision, using MRI and medical imaging. I hope to develop and improve ways to examine brain functions at Kokoro Research Center.
