Ian Power

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

Welcome to, the website for the Power Environmental Geochemistry Laboratory at Trent University in beautiful Peterborough, Ontario, Canada!  I'm an Assistant Professor and Tier 2 Canada Research Chair in Environmental Geoscience as well as a Professional Geoscientist (P.Geo.).  I study natural systems where carbon mineralization processes trap and store CO2 in mineral form, a stable long-term sink for this greenhouse gas. I 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 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.


Carlos Paulo

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.   

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

Applications are invited for M.Sc. and Ph.D. positions with Prof. Ian Power (Tier 2 Canada Research Chair in Environmental Geoscience) in the Environmental & Life Sciences (EnLS) Graduate Program at Trent University to study mineral-water interactions and CO2 mineralization within mine wastes and natural systems.  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.  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, 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 ( providing a cover letter describing your qualifications, resumé, and unofficial transcripts.  All qualified and interested students are welcome!
