I am a Project Researcher at the Department of Civil Engineering, Graduate School of Engineering, The University of Tokyo. My research focuses on computational fluid dynamics (CFD), specifically the development and fundamental mathematical analysis of the Smoothed Particle Hydrodynamics (SPH) method. In addition, I apply these mesh-free particle methods to complex problems in both Earth and planetary sciences and civil engineering.

Featured Research: LS-SPH Method

I have developed a generalized SPH framework based on the moving least-squares method, referred to as the Least-Squares SPH (LS-SPH) method. This method overcomes the fundamental limitation of the classical SPH method (zeroth-order consistency), demonstrating high-order accuracy through several fluid benchmark tests.
