Short Bio and Research Interests

I joined the School of Engineering at Cardiff University in 2010 after postdoctoral studies mainly at RIKEN, UCLA and University of Cambridge. I received my Ph.D in Mathematics at Hokkaido University. I am studying computational fluid dynamics (CFD) mainly
  • Numerical methods in multiphase flows: Level set methods, Volume of fluid (VOF) methods, coupled level set and volume-of-fluid (CLSVOF) methods, THINC schemes, continuum surface force (CSF) models, discrete element method (DEM), Dynamic contact angle models
  • Numerical algorithms: Hyperbolic equation solvers (ENO, WENO), Multi-moment methods (CIP-CSL method, CIP method, VSIAM3), Multigrid method
  • Free surface flow phenomena: Droplet splashing, Droplet impact, Dynamic contact angle, Inkjet, Blood flows, Hydraulic jumps
  • Machine learning.
    If you are interested in our research, please email me.

    A fully funded PhD studentship is available for UK/EU students (Deadline: April 19, 2019)
