Research interests

My research primarily focuses on the modelling and interpretation of optical spectral lines from solar flares. I specialise in radiative transfer with time-dependent atomic populations outside of local thermodynamic equilibrium, and also the application of machine learning to invert this problem in observations in a computationally tractable manner.
