Summary

I am a research fellow in the Fourier-transform Spectroscopy laboratory (group webpage), working with Prof. Juliet Pickering as part of the Space and Atmospheric Physics (SPAT) group. I was awarded my PhD in Laboratory Astrophysics from Imperial College London in 2018 and before that my BSci (Hons) in Physics from the University of Bath in 2009.

My research is focussed on the measurement of fundamental atomic data for astrophysically-important elements using high-resolution spectroscopy.
