Professor of Geology and Geoscience Atom Probe Science Leader, Curtin University

Steve Reddy is a structural geologist and geochronologist with research interests spanning large-scale tectonics to nanoscale material transfer processes.

His expertise lies in the advanced characterisation of geological materials, particularly high spatial resolution microstructural and microchemical analyses. This research has involved innovative integration of analytical techniques to understand material transfer processes.

He pioneered the quantitative microstructural characterisation of accessory phases by electron backscatter diffraction (EBSD) and the integration of EBSD with high-spatial resolution geochemistry and geochronology in major and accessory phases. This has led to new ways of dating crustal deformation and the timing of meteorite impacts.

He is currently working on the distribution and redistribution of trace elements in ore minerals and the how this knowledge may be used as to find giant ore deposits and improve the efficiency of precious metal extraction. He is also the Science Leader of the Geoscience Atom Probe, an initiative to develop the geological applications of atom probe microscopy. In this area, he has been investigating the nanoscale characterisation of mineral deformation by the innovative integration of transmission EBSD and atom probe tomography. This work is leading to a new understanding of elemental transport via mineral defects during deformation.
