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").

With Antonello Provenzale, I have also organized the Gran Combine Summer School, at Aosta in Italy. The theme of the school was "Geomorphological Fluid Dynamics," which draws together ideas and mathematical technology from a variety of problems including the evolution of river basins, the sculpting action of glaciers and volcanic landforms -- see the school's lecture notes which was published by Springer-Verlag as part of the Lecture Notes in Physics Series.

I recently organized a number of activities as part of a Collaborative Research Group on "Complex Geophysical Fluid Dynamics", which was supported by P. I. M. S.
