Specialization: Coastal processes; Beach/Dune Interaction; Coastal Management
I completed my PhD in Geography at the University of Toronto in 1975 and joined the Department of Geography at the University of Guelph in 1976. I retired from active teaching in September 2009 but have continued to be active in research, consulting and advising since then. I taught courses at the undergraduate and graduate level in Physical Geography, Geomorphology, Coastal Processes and Sediment Transport and supervised 35 MSc. and 6 Ph.D. students. During my career my research was funded primarily by grants from NSERC as well as various government agencies. The focus of my research has been primarily on coastal processes, including: morphodynamics of nearshore and intertidal bars; nearshore erosion on cohesive bluff coasts; salt marsh dynamics in the Bay of Fundy; beach/dune interaction; and aeolian sand transport on beaches and coastal dunes. Most of my research has been carried out collaboratively with my graduate students and with a number of colleagues. I have also been involved in applying my research to several aspects of coastal management including serving on two International Joint Commission (Canada/USA) studies and on a working group of the Ontario Ministry of Natural Resources that Produced the Technical Guidelines for management of the Ontario Great Lakes shoreline.
I completed a book on ‘An Introduction to Coastal Processes and Geomorphology’ which was published by Cambridge University Press in January 2010. The book is designed as a text for a senior level undergraduate course in coastal geomorphology and can also be used at the first year Master’s level. It is also designed to serve as a useful review of the field for other coastal scientists and engineers and for coastal managers.
