Michio YAMADA is working on Nonlinear Dynamics including Fluid Dynamics and its related applied mathematical methods. He is particularly interested in those problems related to turbulence and chaos theory, geophysical fluid dynamics, motion of small creatures in fluids and application of wavelet analysis. Recently he has been interested in flow pattern formations in Navier-Stokes fluids on a rotationg sphere, Hamiltonian formalism of fluid equations and its applications. Data analysis method is another topic he is interested in, including application of wavelets and network theory to scientific and social data.
