Graduate

  • Geologically-constrained inversion of airborne EM data over the Athabasca oil sands
  • Time-lapse inversion of electric and EM data for SAGD steam chambers
  • Three-dimensional EM inversion of growth-impeded SAGD steam chambers
  • Detecting and imaging SAGD steam chambers using electromagnetic methods
  • The effect of temperature, saturation, and salinity on the conductivity of heavy oil reservoirs during SAGD processes

Where else you can find me...

Outside of UBC, I'm likely at higher elevations, either mountain biking, snowboarding, or skiing. Throughout summer, I guide mountain bike rides at various levels with my local cycling association TORCA or with the Coquitlam School District mountain bike team. I'm also a director on TORCA's board and primarily focus on writing funding grants, guiding rides, drafting monthly meeting agendas, and working with local and provincial government to legitimize local trail networks. I also volunteer to maintain existing bike trails, plan events, and promote sustainable mountain biking. I am a certified mountain bike instructor and teach at the beginner and intermediate levels with a local start-up company Ozmosis Training. For 2017, I'm an ambassador for Norco John Henry Bikes. Winter equally draws me the mountains, especially on a powder day!
