I am an Associate Professor and head of the EEGL in the Department of Earth and Atmospheric Sciences at the University of Alberta.
I am a biogeochemist who works on environmental aspects of economic geology. I use mineral behaviour, with a focus on crystal chemistry and isotope geochemistry, to understand and manage environmental change in engineered and natural settings.
I develop strategies to tailor element cycles for carbon, metal and metalloid sequestration/recovery in mining environments, mineral processing circuits and engineered landscapes. I draw upon analogous natural systems, and ideas from chemical sedimentology and soil science, to inform my applied work. My research employs fieldwork and laboratory analyses as well as experiments in the field, laboratory and at synchrotron light sources.
