My research interests can be broadly classified as geophysical and astrophysical fluid dynamics (GAFD). Some of the problems in which I’m interested are the generation of planetary magnetic fields via the inductive action of turbulent motions, and the physics of fluid motion in planetary atmospheres. Research in GAFD requires an interdisciplinary approach that draws on many areas of classical physics such as mechanics, thermodynamics and electrodynamics, in addition to relying on several areas of applied mathematics.
