Research
Roger is a member of the Department of Applied Mathematics and Theoretical Physics atomic astrophysics research group. His current research interests are focussed on imporving modelling of atomic processes in plasma. The improvements lead to better diagnosis of various properties of the plasma, such as temperature, density and chemical abundance. The current focus is improving the modelling normally used in the solar corona to better diagnose ions formed lower down in the solar atmosphere, in the transition region and chromosphere. The initial aim has been to model the effect of higher densities on the ionisation and recombination processes involving free electrons which are already included in the coronal modelling. This has been developed further by adding other atomic processes not normally included in coronal modelling, such as those induced by the solar radiation and those which occur during collisions with atoms and ions. Test are currently being made as to how much the new modelling improves understanding of the plasma in the lower atmosphere.
