I use experiments, modelling, and natural samples to understand the behaviour of magmatic volatiles in igneous and atmospheric processes and Earth and other bodies – at the moment particularly sulphur and its isotopes during degassing on Earth and Io! I use these techniques to investigate the influence of volatiles on eruption dynamics, how to interpret gas emission data for volcano monitoring, and model planetary-scale volatile cycling.

I’m currently a postdoctoral scholar in geology in the Division of Geological and Planetary Sciences at the California Institute of Technology. I did my undergraduate at Pembroke College, University of Cambridge, in Natural Sciences (specialising in Earth Sciences), where my master’s thesis investigated how peralkaline magmas fragment despite their low viscosity. I did my PhD at the School of Earth Sciences, University of Bristol, with  GNS Science (New Zealand) where I combined novel microanalytical technique development, experimental petrology, and melt inclusion analysis to understand changes in magma composition prior to eruption.

I like hiking, cycling, climbing and travelling.


What’s new? New paper on understanding how to measure iron and sulphur oxidation states in silicate glass and the effects of beam damage.
