Research interests

Personal webpage: http://www.astro.gla.systa-s.com/users/iain/

My research is focused on the physical processes behind the emission we observe in solar flares (or explosive bursts) in the Sun's atmosphere. I study this primarily through multi-wavelength observations combined with theory and numerical simulations. I am particularly interested in the X-ray emission from small active region flares (microflares and smaller) and the quiet sun, investigating how the Sun's atmosphere maintains its high temperature (the coronal heating problem).
