About

I began my career at Indiana State University (Indiana, USA), focusing on macro-structural geology, where I also conducted biogeochemical research on the eolian (wind-blown) iron and phosphorus flux record of the Southern Ocean over roughly the past twenty million years. From there, I carried on at Washington University in St. Louis (Missouri, USA), where I continued working in structural geology, and added an experimental component to this by conducting rock deformation experiments, characterizing their seismic properties and relating this back to seismic signatures in subduction zones. From there, I moved to l'Institut de Physique du Globe de Paris, where the majority of my research combined experimental petrology (metal-silicate differentiation), planetary and cosmo-chemistry, examined through the lens of trace element and isotope geochemistry. Here, I focused mainly on volatile elements—those easily vaporized, like Zn and Cu—and their isotopes.

At this time, I also began working in the emerging field of Isotope Metallomics - the application of element and isotope geochemistry techniques to medical research, which aims to use such tactics to identify metabolic pathways and potential diagnostics for diseases such as osteoporosis, cancer and Alzheimer’s. Just prior to arriving at JCU, I conducted similar research at Macquarie University (Sydney, Australia), where I began actively pursuing the research and development of rapid and/or automated trace element and stable isotope geochemistry protocols and workflows.

As part of the Earth and Environmental Science (EES) research team at JCU, I apply all these skills and experiences towards building and cultivating such research initiatives within the University, while also expanding along new horizons, such as developing the use of stable metal isotopes as source/process tracers in ore exploration as a part of the Economic Geology Research Unit (EGRU).

My ethos is to develop a high impact and immensely multi-disciplinary research portfolio along with students, postdoctoral researchers, colleagues and collaborators.

--> I am currently growing my research group and looking for Honours, Master's and PhD candidates. Please feel free to contact me with any questions. <---

Waters of Jericho: Characterizing the Cu isotope compostition of water overlying IOCG-style deposaits in the Mt Isa block (Jericho and Eloise deposits)

Indicative Funding
$41,000 over 1 year
Summary
This project is a pilot study that aims to characterize the Cu isotope compositions of borehole waters in 10 km radius around the Jericho and Eloise IOCG type ore deposits. Cu isotopes can act as an ore vectoiring. However, few studies have focused exclusively on natural water samples as a ameans to vector under cover. Novel, efficient techniques are needed as the demand for Cu increases with population and our transition to green energies. A second aim of the project is to stream line the purification of Cu (needed for analysis) to make this more time and cost efficient, and thus more accessible to industry partners.
