Dr. Sylvia Sleep is an Assistant Professor in the Department of Civil Engineering at the University of Calgary. She received her PhD in Civil & Mineral Engineering at the University of Toronto with research focused on applying life cycle assessment to evaluate the greenhouse gas mitigation potential of new oil sands technologies. Prior to starting her faculty position, she completed an Eyes High postdoctoral fellowship in Chemical and Petroleum Engineering at the University of Calgary with a focus on systems-level assessments of carbon capture and utilization technologies. She completed her undergraduate studies in Civil Engineering and Economics at Queen’s University. Her research interests are centered around the development of new methods to assess the life cycle environmental and economic implications of new technologies to aid in decision-making under uncertainty.
