Dr. Kostiuk is recognized nationally and internationally for his engineering achievements in combustion. These include world leading research on industrial flares to create models that quantify emissions to guide operators and regulators to reduce greenhouse gas emissions and protect the environment from the 135 billion cubic meters of natural gas flared annually. He has also contributed fundamental research on flame physics. Dr. Kostiuk has provided effective service to the engineering profession through leadership roles in the NSERC Grant Selection processes, the Canadian Engineering Accreditation Board, the Canadian Section of the Combustion Institute, and the Canadian Society for Mechanical Engineering (Fellow 2011). As Department Chair, Dr. Kostiuk demonstrated academic and educational leadership.
