I am a geoscientist interested in the links between plate tectonics, supercontinent cycles and mineral systems, and the cyclical and secular changes of these through time. I am particularly interested in isotope geochemistry and using computational techniques to analyse large datasets both temporally and spatially.

I am currently a Postdoctoral Researcher with the Geological Survey of Canada and Laurentian University, based in Ottawa, Canada. I am working on a global compilation of isotope data (primarily Pb-Pb and Sm-Nd) to unravel the secular changes in mineral deposits and tectonics throughout Earth’s history. This work aims to understand the relationship between the Pb isotopic evolution of terranes and their mineral endowment, with a focus on the Superior Province in Canada.

I completed my PhD at the University of Adelaide (Australia) in 2019. I primarily used isotope geochemistry, structural geology and statistical/computational techniques to construct models for the tectonic evolution of Madagascar and India during the Precambrian. My research involved integrating large datasets of isotopic data to understand the tectonic evolution of Madagascar from the Archean to early Cambrian. This research contributes to broader aims of reconstructing tectonic plates of the entire Earth from the Neoproterozoic to present using GPlates. I have collaborated with members of the EarthByte Group at the University of Sydney who are working towards these reconstructions.

I worked as a geochronologist/mineral systems geologist at Geoscience Australia from 2014 to 2015, where I worked on the geochronology and geochemistry of the Tasmanides in Eastern Australia. I completed my honours at Monash University in 2013, where I used geophysics, drillcore data and 3D modelling to interpret the structural evolution of a Cu-Au deposit in South Australia.
