Overview
I specialise in the formation of magmatic-hydrothermal ore deposits, with expertise in integrating macro-scale field observations with multiple layers of micro-scale textural, geochemical and geochronological data. My PhD focused on unravelling the archetypal Yerington porphyry system of Nevada, with publications including a Scientific Reports’ ‘Top 100’ of 2022, and I gained Post-Doc research experience on the EU Horizon 2020 GREENPEG project (see https://www.greenpeg.eu/ for more information). Prior to moving into magmatic-hydrothermal systems, I worked for BP in Operations, Wellsite, and Well Planning geology roles after completing an MSc in Mining Engineering and BSc in Applied Geology at Camborne School of Mines. I continue to provide exploration and research consultancy services to major-, mid-tier-, and junior-mining companies around the globe.
