Dr. Iain D. Stewart is a Postdoctoral Fellow at the Global Cities Institute in the Daniels Faculty of Architecture, Landscape and Design, University of Toronto. He is the lead researcher on a Toronto-based interdisciplinary study of the urban metabolism of megacities. Before coming to Toronto, Iain was Postdoctoral Research & Teaching Fellow at The University of British Colombia (UBC Vancouver), where he completed his PhD in Geography in 2011. Iain’s research interests include the energy, water, and waste flows of cities and their effects on sustainable urban development; and the influence of urbanization on local and microscale climates, especially the urban heat island effect. Iain’s research at UBC helped to establish scientific guidelines and standardized methods for urban climate studies, in particular for the exchange of air temperature data among cities worldwide. His research has been published in the International Journal of Climatology, the Bulletin of the American Meteorological Society, and The Canadian Geographer. Iain is twice recipient of the William P. Lowry Memorial Award, given for his advances in climate methodology by the International Association for Urban Climate.
