Research Interests

Magnetohydrodynamics (MHD)

MHD is a union of fluid dynamics and electromagnetism and plays an important role in our understanding of a broad range of phenomena, from eruptions on the Sun to describing the geodynamo to the stability of fusion plasma devices.


One of my main research interests is astrophysical fluid dynamics, where MHD has a very important position. I have worked on, and continue to research, dynamic phenomena in the solar atmosphere.  Much of my work has focussed on magnetic flux emergence - the process by which magnetic fields rise through the layers of stars and expand into the atmosphere. This is an interesting blend of many areas of MHD, including instabilities, reconnection, magnetic topology, waves and eruptions. I have also worked on MHD equilibria and reconnection in their own right, with an eye towards solar applications.

My work in MHD is a mixture of analytical and computational modelling. As many of the interesting aspects of MHD are 3D and nonlinear, a numerical approach is required, implying the use of high performance computing.

If you are a potential PhD student and would like to know more about this exciting research area, please look at the Postgraduate opportunities section and/or get in touch with me.
