I am an Oxford-Radcliffe Scholar at University College, University of Oxford researching subduction zone geochemistry in the Lesser Antilles. I graduated with an MEarthSci from the University of Oxford in 2024. During my integrated Master’s programme, I won the Keith Cox Prize for best 2nd Year Mapping exercise in Assynt (2022), the Gibbs Prize for Best Mapping Project (2023), and an Academic Scholarship at St Anne’s College for all four years of study. In Summer 2022, I won a NERC Research Experience Placement with the C-Clear DTP where I researched the impact of polar atmospheric ozone loss due to bromine chemistry with Xin Yang as part of the Atmosphere, Ice and Climate team at the British Antarctic Survey and University of Cambridge. My Master’s research investigated whether the behaviour of sulphur during the 2020-2021 eruption of La Soufrière volcano (St. Vincent) could be used to determine the cause of the eruption style transition from effusive to explosive in this event using erupted projects from both this and the 1979 eruption, under the supervision of Elena Melekhova and Michal Camejo-Harry. During Summer 2024 I worked as a research assistant with Jon Blundy and Elena Melekhova, University of Oxford, to classify and analyse the St Vincent xenolith sample suite, collected over several field campaigns in the 2010s, to determine the abundance and distribution of sulphide-bearing lithologies.
Current Research
My research focuses on understanding variations in the formation and accumulation of crustal sulphides along volcanic arcs. Previous work has shown that the copper content of magmas erupted in volcanic arcs varies in response to crustal thickness. This DPhil project examines whether crustal sulphide composition and abundance vary consistently along-arc with crustal thickness, using a range of elemental and isotope analyses on crustal xenoliths to calculate a crustal sulphur budget for different locations along the active Lesser Antilles Arc. This work will contribute to a better constraint of the sulphur budget of intra-oceanic volcanic arcs, with an application to global models of the sulphur cycle, as well as gaining insight into how variations in subduction zone parameters, specifically crustal thickness, impacts magmatic processes and the behaviour of sulphur.
