I am a high temperature geochemist with a background in volcanology and igneous geology. I use isotopes to constrain Earth System processes related to magmas and am currently interested in the processes of metal transport in active systems. As part of the MinEx CRC, I'm working on developing metal isotopes to look for mineral prospectivity in South Australia.
Monogenetic and arc volcanism - How do volcanic deposits reflect magma genesis and ascent?
Basalt geochemistry - what does it tell us about the mantle source and how melts are released?
Mantle heterogeneity - how heterogeneous is the mantle really and on what temporal and spatial scale?
Uranium series chemistry (U-Th-Ra-Pb isotopes) to address timescale questions in igneous systems
Ore deposit genesis (new!) - what are the essential ingredients to form ore deposits and where can we find the next big one?
Much of my research since my MSci in the UK has centred around using the compositions of basalts erupted in small eruptive volcanic centres to understand the composition of the mantle, the way in which it melts and how these are reflected in small-scale volcanic deposits. My PhD work at the University of Auckland (supervised by Ian Smith and Jan Lindsay) focussed on the melting processes which have given rise to a city of miniature, Quaternary-age volcanoes: the Auckland Volcanic Field. During this time I studied the field using several key examples, and worked on its possible end-member basalt compositions with the use of radiogenic and U-series isotopes and major and trace element modelling. ‘Monogenetic’ certainly doesn’t mean ‘monotonous’!
In my 3-year postdoc at the University of Chile (in addition to trialling U-Th dating on geothermal carbonates, as part of my project with the Andean Geothermal Centre of Excellence) I continued the theme of small volume basalts after being awarded a 3-year grant from the government. This time the volcanoes were in a far more complex arc context and in close proximity to large, active stratovolcanoes (the Pucon small eruptive centres close to Villarrica volcano, the Carran-Los Venados field close to Puyehue-Cordon Caulle volcano and the Antillanca volcanic complex, all in the Southern Volcanic Zone of Chile). I worked with Macquarie University in the U-series area of this project which provided important information on competing tectonic and source component-related signatures. I still continue to work with researchers from the Universidad de Chile and SERNAGEOMIN (the geological survey of Chile) on several volcanology-related projects in different areas of Southern Chile.
During my 2.5 year postdoc at Macquarie University I worked on what triggers explosive eruptions, applying the short lived isotopes of 210Pb and 226Ra (in the Uranium series decay chain) to recently erupted rocks from Soufriere Hills volcano in the Caribbean to examine the idea that volatile exchange is a major driver of explosive volcanism.
As part of the MinEx CRC I will be working on developing metal isotopes to look for mineral prospectivity in South Australia.

January 2022- present: ANZIC (Australian and New Zealand International Ocean Discovery Program Consortium) Legacy grant for the project: "Metal isotopes applied to the start of subduction: testing the fluid transfer of copper from slab to surface" in collaboration with Prof Mark Reagan (University of Iowa) and A/Prof Julie Prytulak (Durham University). Awarded $16,500 AUD to analyses a suite of samples from the Bonin oceanic arc which preserve a record of the magmatic products of subduction initiation, sampled by IODP Exp. 352. We will examine the role of the slab in the transition from decompression melting to fluid fluxed melting due to dehydration. Fluid-sensitive Cu isotopes on pristine glasses taken through the forearc to arc transition should fingerprint the first low temperature aqueous fluid contributions from the slab, ultimately determining the source of Cu: the slab or the mantle. This has significance for our understanding of magma petrogenesis during subduction initiation, in addition to processes which may transport and potentially concentrate chalcophile elements.
Previous grants: August 2019 - November 2021: ANZIC (Australian and New Zealand International Ocean Discovery Program Consortium) Legacy grant for the project: "Calibrating metal isotope proxies in modern hydrothermal environments for ancient ore deposit applications". Awarded $19,500 AUD to investigate the metal transport system in modern, active hydrothermal systems using a combination of redox sensitive metal isotopes and radiogenic magmatic-environmental sensitive isotopes. Studying in detail the behaviour of metal species in modern-day oceanic settings allows us to relate chemical behaviour directly to processes, something which is much harder to establish in ancient terrestrial settings, and which is critical for the new age of mineral exploration.
