Research

My research team and I use mineral behaviour (with a focus on crystal chemistry, isotope geochemistry and mineral–fluid–microbe interactions) to understand and manage environmental change in engineered and natural landscapes. Our core interest is in learning how crystal chemistry controls the biogeochemical evolution of landscapes.

We are working to understand and tailor cycling of volatile nutrients, metals and metalloids in natural landscapes, mining environments and ore processing circuits. This allows us to develop new science for recovery of valuable metal resources from mineral wastes, mitigation of metal and metalloid mobility in mining environments, and carbon mineralization (CO2 sequestration) using waste materials. Our applied studies in mining environments are supported by fundamental research including mineral behaviour experiments and field-based studies in natural sedimentary systems, particularly saline lakes and weathered meteorites.

Our technical strengths are in applied and environmental mineralogy (including clay mineralogy), X-ray analytical techniques, aqueous and sediment geochemistry, and stable isotope geochemistry. Our research employs field sampling and laboratory analyses as well as experiments in the field, laboratory and at synchrotron light sources.
