For my masters degree (MSci) in Earth Sciences I worked with Marie Edmonds and Alexandra (Sasha) Turchyn, compiling and analysing a database of carbon and helium isotopes from over 80 arc volcanoes. Using this dataset we were able to show that arc volcanoes with the highest (most carbonate-rich) carbon isotope signatures also have low helium isotope values and the highest CO2 emissions, suggesting that remobilisation of crustal carbon may dominate arc emissions. Our work also has implications for estimates of fractional organic carbon burial and therefore Earth's habitability over geological time (see link to paper below). 

My PhD research focuses on metal emissions from arc volcanoes and how processes deeper in the magmatic system such as the affinity of metals for different phases (melt, vapour, sulphide), as well as the timing of this partitioning produce the compositional fingerprint seen at arc volcanoes. I am also interested in understanding how and why these processes differ at other tectonic settings.
