Academic Degree
Doctor of Philosophy in Science
Field of Specialization
Fluid dynamics, nonlinear physics
Outline Activities
While the nonlinear phenomena take on highly complex aspect, there are some coherent structure --- vortex, solitary wave etc. My research aims to understanding of this structure. I investigate, theoretically,numerically and experimentally, two-dimensional interaction of the solitary waves and waves generated in the flow by topography etc.
