Research

I am a member of the Department of Applied Mathematics and Theoretical Physics  Atomic Astrophysics research group. My current research interests are on energy transfer processes in the solar corona.

Atomic physics calculations and plasma diagnostic techniques applied to XUV spectroscopic observations allow the measurements of plasma parameters such as electron density, temperature, chemical abundances. In conjunction with modeling, they can help us in understanding how magnetic energy is transferred into heat in all varieties of solar coronal features, from active region loops to solar flares.

I have also been working on measuring the solar EUV irradiance and its variations during the last solar cycle, and how these variations can be modeled and models applied to other stars.

I contributed to atomic data calculations (within the UK APAP network), to line identifications and benchmarking atomic data against laboratory and astrophysical spectra, to atomic data distribution via the CHIANTI atomic database and VAMDC.
