Updated on 2022/05/19
My research mainly focuses on nonlinear partial differential equations describing the motion of viscous fluids. I am interested in the application of some abstract functional analysis and harmonic analysis.
I received the Ph. D. degree in science from Waseda University in 2020 under the supervision of Prof. Yoshihiro Shibata. I am currently an Assistant Professor in the Global center for Science and Engineering at Waseda University.
