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 am currently a Volcanic Fluid Geochemist in the Volcanology Team at Te Pū Ao | GNS Science and part of the Technical Team for Volcanica, the Diamond open-access journal for all things volcano-related. 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  Te Pū Ao | 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. Following that, I was a postdoctoral scholar in geology in the Division of Geological and Planetary Sciences at Caltech.

I like hiking, cycling, climbing, and travelling.


What’s new? (as of 11/08/2021)

I’ve joined the Volcanology Team at Te Pū Ao | GNS Science as a Volcanic Fluid Geochemist!

New pre-print on the geochemistry of basalts from the Okataina Volcanic Centre, Taupō Volcanic Zone, Aotearoa New Zealand.
