My research interests are in applied mathematics, which means just about anything. Most problems are interesting, and many of them can be couched in a mathematical language that provides insight into them. More specifically, my interests have in the past focused on astrophysics, chaos and dynamical systems, and fluid mechanics with particular application to geophysical fluids.

Depending on my current level of funding, I am happy to take on graduate students for both a M.Sc. and Ph.D. Look here for more information

I am closely associated with the Geophysical Fluid Dynamics summer school, Woods Hole Oceanographic Institution, and have directed various summer programs ("Astrophysical and Geophysical Flows as Dynamical Systems", "Stirring and Mixing", "Conceptual Models of the Climate", "Non-Newtonian GFD", "Tides", "Perspectives and Challenges in GFD", "Swirling and Swimming in Turbulence").

Short descriptions of some of my current research themes follows below, together with links to some relevant articles:

Non-Newtonian Fluid Dynamics And Applications In Geophysics
