General interests:
  • Patterns in fluid flows and their stability to perturbations.
  • Transition to turbulence and chaos in shear flows.
  • Generation of magnetic fields by the motion of fluids, e.g. the geodynamo.
  • Founder of openpipeflow.org.

How about a PhD with me?

I am always looking for motivated students who would like to apply and broaden their mathematical skills. As the focus of my projects is usually on the development of mathematical methods and the study of dynamical systems, I expect you to be familiar with differential equations and vector calculus, but you do not need to have taken advanced courses on fluids.

The modelling of fluid flows is perhaps the traditional test-bed for the development of new methods. Often, even simple-looking setups exhibit all sorts of interesting phenomena, 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 in modelling flows in the interior of planets. The latter is usually responsible for the generation of planetary magnetic fields.

For further information please contact me. The following links to snippets of my work may also be of interest: Turbulence. Dynamos.
