I am a geoscientist with CanmetENERGY-Ottawa. I conduct research on the geological storage of CO2, the integrity of oil and gas wells, and geothermal energy.

Current research and/or projects

My research is focussed on determing the purity requirements for CO2 stored in the subsurface, developing novel wellbore remediation technologies, and advancing geothermal energy development in Canada.

Research and/or project statements

  • Technology Roadmap to Improve Wellbore Integrity.
  • Effect of impure CO2 streams on geologic storage of CO2.
  • Use of biomineralization to fix leaky oil and gas wells.
  • Advancing geothermal energy in Canada.

Professional activities / interests

  • I jointly led, in collaboration with the Wellbore Integrity and Abandonment Society, the production of a Technology Roadmap to Improve Wellbore Integrity.
  • I have been a key contributor to supporting NRCan's efforts to advance our geothermal energy resources. 
  • My work involves collaborating with universities and other research institutions, including the universities of Alberta, Waterloo, Ottawa, and Uppsala; Alberta Innovates - Technology Futures, and the US Department of Energy.
