B.Sc. and Ph.D. (Western University), P.Geo. (BC)

Welcome to PowerGeoLab!  I'm an Assistant Professor and Tier 2 Canada Research Chair in Environmental Geoscience as well as a Professional Geoscientist (P.Geo.).  My team is researching a wide variety of geochemical, mineralogical, and geobiological processes related to CO2 mineralization and carbon cycling. We employ controlled laboratory experiments and detailed mineralogical and geochemical analyses to understand the drivers and limitations of geologic processes that sequester CO2. One practical and novel application involves trapping CO2 within mine wastes to reduce GHG emissions of mining, an industry that contributes significantly to Canada’s economy.

My interdisciplinary approach to science crosses conventional research boundaries to discover, understand, and harness processes that have the potential to reduce GHG emissions while training a new generation of scientists to tackle these pressing environmental issues.

B.Sc. (Trent University)

I'm a M.Sc. student researching mineral carbonation processes, where CO2 is trapped and stored in stable carbonate minerals. I am conducting fieldwork in South Africa and laboratory experiments that will help to further understand mineralogical processes related to CO2 sequestration in mine wastes. I am interested in the reactivity of mine waste to determine if there is potential for CO2 sequestration and rates of passive (unintentional) carbonation occurring at active diamond mines. My goal is to develop processes that will offset greenhouse gas emissions in the mining industry.

Ph.D. (University of Toronto)

I am a Postdoctoral Fellow working on strategies to enhance mineral carbonation in ultramafic mine tailings. A key aspect of my research is the assessment of the chemical reactivity of mine tailings with atmospheric carbon dioxide. Towards this goal, I am designing laboratory-scale experimental tests to estimate carbonation rates, as well as favorable geochemical conditions for carbonate precipitation in mine tailings. These laboratory technology demonstrations will provide crucial information for the development of field pilot projects.

Remy K-Pow

I am a lab labradoodle, rock hound, and the official mascot of the PowerGeolab *bark* My research interests include digging holes, sniffing out rocks, taste analyzing dirt minerals, and testing nutrient amendments on grass and carpet *ruff* I am part lab, but my true passion is fieldwork where I can assist my team members by lifting morale, hauling samples, and warning of danger (when I get bigger)!

recruiting undergraduate, M.Sc. and Ph.D. students

We’re recruiting enthusiastic students for M.Sc. and Ph.D. theses to study mineral-water interactions, CO2 mineralization within mine wastes, enhanced weathering, natural analogues for carbon sequestration, and biocementation.  Research will consist of laboratory experiments and fieldwork to understand geochemical and mineralogical processes relating to CO2 mineralization, a process by which CO2 is sequestered within carbonate minerals.  Fieldwork may include campaigns to Canadian and international localities including South Africa.  Prospective students should be highly motivated, preferably hold a degree in either geoscience, geography, environmental science, chemistry, or closely related field, and must meet the entry requirements for graduate research in EnLS at Trent University. The ideal candidate will have a strong academic standing, field and laboratory skills, knowledge in geochemistry and mineralogy and related disciplines, excellent communication (written and oral) skills, strong work ethic, and a passion for science.  Research experience at any level is highly advantageous.  

Interested in joining the team?  Please email Dr. Power ( to learn more about the exciting research that we’re doing in the PowerGeolab!  

All qualified and interested students are welcome!
