Professor University of British Columbia, Research Lead on Theme 4: Particulate Emissions & Properties
Prof. Steve Rogak is a Professor of Mechanical Engineering at the University of British Columbia. Prof. Rogak is an acknowledged expert on the morphology, transport properties, and aerosol dynamics of aerosol nanoparticles, with 1,500 citations of his papers on these topics. His early contributions include practical mobility and charging models for aerosol aggregates, critical to the interpretation of measurements by mobility instruments (such as the scanning mobility particle sizer [SMPS]). Over the last 20 years he has developed systematic approaches to the analysis of transmission electron microscope images, applied to particles from furnaces, wood stoves, jet engines, heavy and light duty engines, a variety of burners, and supercritical water oxidation. Recently Rogak and Ph.D. student Ramin Dastanpour discovered that most combustion-generated aggregates show structural variations (previously unreported) that can be considered a “fossil record” of inhomogeneous formation conditions. This new idea will be further tested and extended in the proposed work. Rogak has also done important practical work with Westport Innovations, finding fuel injection strategies to reduce soot emissions from direct-injection natural gas engines. Prof. Rogak is an active member of the Publications Committee for the American Association for Aerosol Research and a frequent reviewer for Aerosol Science and Technology, the Journal of Aerosol Science, Carbon, and SAE. He is based in Vancouver, B.C.
