Research interests
As a mineral physicist, I employ cutting-edge materials science characterization approaches such as multiscale tomography (x-ray, focused ion beam, scanning transmission electron microscopy and atom probe tomography) and machine learning algorithms to address fundamental questions about the evolution of the Earth and interactions of life with its environment. My expertise has its foundation in my background as a nanofabrication researcher1–3 and a statistical process control engineer with the FEI Company. I have applied my experience with state of the art electron microscopy techniques to advance the characterisation and understanding of ancient Earth and planetary materials4–8. Multiscale correlative approaches have been key in determining the extent to which Archean zircons record primary magnetic signals on the early Earth and hence establish the earliest time for life to develop. Recently, I have advanced the correlative microscopy methodology, through the development of correlative microanalysis.9 By connecting multiple microscopy data types, I am able to demonstrate mineral phase relationships in quantitative and data driven approach. These insights work to inform and contextualise geochemical and paleomagnetic understanding. Currently, I am applying these methods to examine, Archean terrains, meteorites and energy critical element mineral relationships.
