Biography

Dr. Dirszowsky obtained his undergraduate and graduate degrees in Geography from the University of Toronto. He also taught extensively in the Department of Geography at the University of Toronto and at Queen's University as an Advisory Research Committee/Principal's Development Fund Postdoctoral Fellow. He taught for one year at Carleton University before taking up a permanent position at Laurentian University where he is now appointed to the School of the Environment and a research associate of the Cooperative Freshwater Ecology Unit. His teaching interests are in the Earth and Environmental Sciences with emphasis on connections between sub-disciplines and other areas of Environmental Studies. He has taught introductory courses in Physical Geography, Earth Sciences, GIS, Geomorphology and Pedology, Hydrology and Climatology, and advanced courses in Quaternary Paleoclimatic Reconstruction and Physical Geography and Earth Science Research Methods and Field Methods. His research activities and interests focus on sediment production/movement in watersheds and lacustrine systems, landscape evolution, environmental change and paleolimnology. He is currently working to distinguish natural (climate change) and anthropogenic impacts on the sensitive and, in some cases, highly disturbed boreal shield landscapes near Sudbury in northeastern Ontario. Additional research is or has been carried out in Alberta, British Columbia and the Northwest Territories, the Antarctic Peninsula region, the French/Italian Alps and Venezuelan Andes.
