My research interests are in understanding nonlinear dynamical phenomena observed in the evolutions of incompressible fluid motions;

(1) Topological fluid mechanics (Topological Flow Data Analysis)
(2) Dissipative weak solutions of the Euler equations and Turbulence theory
(3) Vortex Dynamics (Point Vortex on Closed Surface)
(4) Flow control of vortex dominated flows
(5) Singularity formation and long-time behavior of vortex dynamics
(6) Applied and Computational Complex Analysis
(7) Interdisciplinary Studies (Mathematical Meteorology, Math Clinic at Kyoto U)
