Research interests

I am primarily interested in astrophysical fluid dynamics and nonlinear phenomena with particular interests in magnetohydrodynamics (MHD). This branch of fluid dynamics involves the study of the interaction of magnetic fields with electrically conducting fluid dynamics and is particularly important in explaining the solar activity cycle.


Research Topics








butterfly diagram

This is a colour-coded image of a butterfly diagram for a computer-generated solar dynamo model The model is of a "mean-field" dynamo where the nonlinearity is the back-reaction of the mean magnetic field on the differential rotation.
