COLLIN PHILLIPS

Senior Lecturer, Mathematics Learning Centre


My research field is Magnetohydrodynamics (MHD). MHD concerns the interplay of conducting fluids and magnetic fields within the Earth, planets, the Sun, stars and galaxies. My research addresses an important unsolved aspect of MHD — modelling physically relevant parameters of the Earth's core (and the interior of stars) with motion that is considered to be turbulent, small scale and rapid. I have developed, with Dr David Ivers, a method of modelling the parameterised effects of these small scale fields on the larger computationally resolvable dynamos of the Earth and stars. This parameterisation of anisotropic diffusion is one of three current approaches addressing this problem of dynamo theory.
