Research interests

Personal webpage: http://www.astro.gla.ac.uk/?p=123

My research interests are in the field of solar coronal and flare physics. I work on the analysis of imaging and spectral data from solar space missions, such as RHESSI, Hinode and SDO, solar image processing, numerical simulation of fast particle transport in magnetised plasmas, and flare and active region magnetic field structure.
