Research Interests

My research interests are in two distinct branches of Applied Mathematics. I have an active interest in Mathematical Physiology, in particular, the application of non-linear analysis, singular perturbation and asymptotic methods to study the properties of electrical waves in cardiac tissue and other excitable media. The other major direction of my research is Fluid Dynamics and Magnetohydrodynamics. In this area, I use a combination of analytical techniques and carefully designed numerical experiments to study convection in rotating systems and self-consistent hydromagnetic dynamo action. This research is motivated by applications to geo-, planetary and solar magnetism.
