I am a geologist with a background in industry, research, and academia. My work focuses on ancient sedimentary systems with potential for base-metal mineralisation and energy resources. I use novel and traditional geochemical and geochronological tools to understand when basins form, what environments they formed in, and whether or not they have been altered afterward. By constraining these processes, I can help better define what controls the accumulation of sediment-hosted economic targets. The tools I specialise in include new in situ applications of the Rb-Sr and U-Pb methods, stable isotopic systems (eg. C, Ca, and Sr), and redox-sensitive trace element proxies.
I was awarded my Bachelor of Science majoring in Geology and Geophysics at the University of Adelaide in 2018 with First Class Honours. I began my career as a geologist working on vein-hosted gold systems and iron-oxide-copper-gold deposits in the Northern Territory and South Australia, respectively. I returned to the University of Adelaide to undertake a PhD in Earth Sciences, completing my thesis in 2023. My PhD research was on the sedimentary geochemistry and geochronology of the Proterozoic greater McArthur Basin, northern Australia.
