Theoretical and computational astrophysics, including solar and stellar convection, magnetic dynamo action within stars, turbulence in many settings, and helioseismology. Central to this is theoretical work involving modern fluid dynamics, often based on 3-D simulations on supercomputers, that can be challenged and tested by astrophysical observations.
