Work with me!
PhDs: I am interested in supervising motivated students with a strong mathematical background, in applying their knowledge and learning new techniques for the study of dynamical systems. An excellent setting for new methods, perhaps the traditional test-bed, is the modelling of fluid flows. Unexpected transitions in flow patterns and chaotic behaviour are commonplace, and our understanding of nature is greatly enhanced through numerical simulation and experiments. I am particularly interested in the appearance of turbulence in fluid flows, and modelling of the flows inside planets. The latter is usually responsible for the generation of planetary magnetic fields. For further information please contact me. The following links may also be of interest
