Astrophysical fluid dynamics with emphasis on convective dynamics and scale selection, turbulence, the excitation of the solar/stellar p-modes, and the origin of solar/stellar irradiance variations.
Investigations range from studying highly simplified turbulent analogs based on point vortex motions to highly realistic simulations of radiative magnetohydrodynamics, spectral synthesis, and spectropolarimetric inversions.
Also involved in the development of the Critical Science Plan for the National Solar Observatory's (NSO's) upcoming 4m solar telescope, the Daniel K. Inouye Solar Telescope (DKIST).
