Cariboo portrait I am an Associate Professor and the Canada Research Chair in Biogeochemistry of Sustainable Mineral Resources. I lead the EEGL in the Department of Earth and Atmospheric Sciences at the University of Alberta.

I’m a biogeochemist whose work focuses on environmental aspects of economic geology and on chemical sedimentology. I use mineral behaviour, with a particular focus on crystal chemistry, to understand and manage environmental change in engineered and natural settings.

The team at the EEGL and I are developing strategies to tailor element cycles for carbon, metal and metalloid sequestration/recovery in mining environments, mineral processing circuits and other engineered landscapes. The group and I study analogous natural systems, and draw upon ideas from chemical sedimentology and soil science, to inform our applied work.

I’m currently focusing on (1) pilot-scale implementation of enhanced weathering for Carbon Capture Utilization and Storage in mining environments and (2) non-classical mineral behaviour in sedimentary systems, including the amorphous-to-crystalline transition, water-efficient gas–mineral reactions, and the impact of path dependence during mineral phase transitions on trace element and stable isotope inventories in sediments. My research employs fieldwork, laboratory analyses, and experiments in the field, laboratory and at synchrotron light sources.
