Professor, Department of Mathematics, Kyoto University and Chief coordinator, Math Clinic at Kyoto University.

My research interests are in understanding nonlinear dynamical phenomena observed in the evolutions of incompressible fluid motions; I am also intersted in interdisciplinary mathematical studies (Math. Metorology, Math. Modeling etc); I am the chief cordinator of Math Clinic Program (MACS Program)

I am awarded a JST PRESTO research fellowship for the project, href="presto19/presto.html"> "Dynamical Systems Theory for Hydrospheric Environments"(2007-2010) and the sequel project of JST Math CREST, "Towards a Paradigm Shift Created by Mathematics of Vortex-Boundary Interactions" (2010-2016).

  • Dissipative weak solutions of the Euler equations and Turbulence theory
  • Vortex Dynamics (Point Vortex on Closed Surface)
  • Flow control of vortex dominated flows
  • Singularity formation and long-time behavior of vortex dynamics
  • Applied and Computational Complex Analysis
  • Interdisciplinary Studies (Mathematical Meteorlogy, Math Clinic at Kyoto U)
