- Honorary Research Fellow (School of Mathematics and Statistics)
My main research interests lay in the field of fluid dynamics, and in particular the nonlinear dynamics of turbulent flows. I have focused on the nature of turbulence in very low temperature systems, where quantum mechanical effects become very important. Here the absence of friction, and the quantization of vorticity dramatically change the nature of the turbulence, allowing us to make new insights into the problem. I am also interested in the complex motion of electrically conducting fluids, and the self-generation of magnetic fields due to a fluid dynamo. Most recently I have been involved in the mathematical modelling of prehistoric population dynamics, with applications to the spread of farming in the Neolithic epoch.
