The main focus of my research is magnetohydrodynamic (MHD) modelling of three-dimensional magnetic fields, with applications to astrophysical plasmas. I am particularly interested in the theory of magnetic reconnection in three dimensions. I am part of the MHD research group - click here to visit the MHD Group Homepage.
In 2011 I was awarded a Philip Leverhulme Prize.
