The world around us is filled with string-like structures, from micro to macro-scales, and even to space and the galactic scales. They are fluid vortex filaments, elastic strings, or magnetic flux tubes. It is not difficult to imagine that the nonlinear and unsteady dynamics and their stability play a major role in shaping the world. Vortices hold a key to unlocking secrets of the universe and controlling nature. From the view that "vortices" and "waves" are ingredients constituting fluid motions, I am developing mathematical methods for calculating vortex motion and its stability, with the aid of numerical calculations. They provide a cutting-edge knowledge about the speed of motion of vortex rings and vortex tubes and the three-dimensional stability of vortex rings.

In the magnetohydrodynamics (MHD), the magnetic fields share, with the vorticity fields, a common property that, for ideal fluids, they are frozen into the fluid and thence are carried by the flow. This topological aspect should be distinguished from the dynamical aspects expressed in terms of the momentum and the energy, and the former are better expressed in Lagrangian rather than Eulerian terms. The Lagrangian descriptions that trace the motion of individual fluid particles have traditionally been avoided as being redundant, but recently we have demonstrated that the Lagrangian description is powerful and even essential in calculating vortex motion and stability. Our major goal is to construct vortex motion using Lagrangian descriptions and use them to model complex wave turbulence.

Since around 2010, I have been working on industry-academia collaborative research and interdisciplinary research with other fields. I am working on materials informatics in collaboration with chemical material manufacturers, and on slope disaster (landslides) prediction and prevention with geotechnical engineers in academia and companies. For our research on analysis of groundwater flow using Darcy's law, we were invited as a problem presenter a problem at the European Study Group of Mathematics in Industry ESGI 135 (June 2023, Ireland).
