Tohoku University

Visiting associate professor at the institute of fluid science (IFS). Conducted basic and translational research on the hemodynamics and mechanobiology of intracranial circulation​[1–3]​. Co-designed and analyzed PIV experiment series for cerebral aneurysm hemodynamics, ultrasound velocimetery and CFD simulations of cerebral aneurysm​[4]​, carotid stenosis and Moyamoya disease.
