Personal profile
Biography
I received my MSc from McGill University in Canada in 2012 and my PhD from the University of Western Australia in 2019. Between completing my MSc and starting my PhD, I worked as an exploration geologist in Australia for three years.
My PhD research focused on using a multidisciplinary and multi-scale approach to investigate the formation of high-grade gold mineralisation at the world-class Callie gold deposit in the Tanami region of the Northern Territory, Australia.
I worked as a Research Fellow at the Centre for Exploration Targeting (UWA), where my research investigated the mechanisms of gold transport and deposition associated with high-grade gold accumulation in orogenic deposits. My focus was to contribute to a deeper understanding of high-grade gold systems that can support mineral exploration.
I am currently a Research Fellow at the John de Laeter Centre, working with the Geoscience Atom Probe (GAP) Facility at Curtin University.
