Researcher biography

Grant has degrees in both Chemistry and Earth Sciences and is presently focused on assessing the environmental impact of fluid-rock interactions on groundwater chemistry. This entails a variety of rock characterisation techniques (elemental, mineralogical, petrophysical), benchtop sequential extraction experiments, and pressure vessel experiments that mimic in-situ conditions deep underground, with data then fed into geochemical modelling software. The analytical equipment that Grant has operated to achieve his research outcomes includes ICP-MS, ICP-OES, SEM-EDS, Microprobe, XRF, Synchrotron XFM beamline, Petrographic Microscopes (both scanning and standard), Gas Permeameter, Helium Pycnometer, Pressure Vessels, etc. Grant also has an active interest in the geological storage of carbon dioxide, both via injection into deep geological formations and direct atmospheric capture facilitated by rock weathering to form stable carbonate rocks (mineral trapping of CO2). In the past, Grant has studied natural carbonate mineralisation (both veins and cement) throughout the Great Artesian Basin, to explore the variety of natural conditions that promote the transformation of CO2 into minerals. Early in his research career, Grant participated in paleo-climate research projects that involved botanically describing and assessing the cell morphology of fossil woods, coal petrography, studying coral cores, and picking foraminifera recovered from the sea floor.
