Geophysical fluid dynamics: I study wave propagation in geophysical fluids (oceans, atmosphere, Earth's deep interior) using simplifying approximations. My most recent work involves wave propagation associated with the behavior of the Earth's magnetic field.

My primary interest is in geophysical and astrophysical fluid dynamics. I use certain approximations to simplify the complicated equations governing these phenomena. The problems I usually work on are related to the generation and behavior of the magnetic fields of various objects, including the Earth, other planets, and the sun. I have a secondary interest (but haven't done much) in mathematically modeling certain biological problems, in particular, some problems in cell signaling.
