Dr. Claire Oswald is an Assistant Professor in the Department of Geography and Environmental Studies at Ryerson University in Toronto, ON. Dr. Oswald is a broadly-trained physical geographer with research interests in catchment hydrology, biogeochemistry, pollutant (e.g. mercury, chloride) fate and transport, and dissolved organic matter quantity and quality. These interests span both natural and human-dominated landscapes, from the Boreal forests of northwestern Ontario to constructed wetlands in the Alberta Oil Sands Region to urban and urbanizing watersheds in south-central Ontario. Dr. Oswald holds a PhD (2011) in Physical Geography from the University of Toronto, an M.Sc (2002) in Physical Geography from McMaster University and a B.Sc (1999) in Physics from McMaster University.
Dwayne Keir joins the group from Saskatchewan, where he
previously worked at Environment Canada and as a municipal community planner. Dwayne's Masters research in the Environmental Applied Science and Management (EnSciMan) program is focused on the historical hydrography of Mimico Creek, which flows through the western Greater Toronto Area into Lake Ontario.
Colin Ash is completing his Masters through the EnSciMan program and is co-supervised by Stephanie Melles from the Department of Chemistry and Biology. Colin's research is focused on understanding fine-scale spatial variations in in-stream chloride concentrations across three watersheds that span a gradient of urbanization. Colin's research is funded through an Environment Canada Lake Simcoe/Southeastern Georgian Bay Clean-Up Fund grant.
Michelle Lucas is completing her Masters through the EnSciMan program and is co-supervised by Lynda McCarthy in the Department of Chemistry and Biology. Her research focuses on assessing the potential impacts of elevated chloride concentrations on the abundance and diversity of benthic macro-invertebrates in several urbanizing headwater catchments. Michelle's research is funded through an Environment Canada Lake Simcoe/Southeastern Georgian Bay Clean-Up Fund grant.
Doug Seaborn worked in utility, telecom and local government GIS applications for 30 years around the world before deciding to refresh his technical skills in the Masters of Spatial Analysis (MSA) program housed in the Department of Geography and Environmental Studies. His research is exploring relationships between water quality deterioration and land use changes in the Nottawasaga River watershed. Doug hopes that his work will encourage better stewardship of land use in the years ahead.
Mallory Carpenter is completing her Master of Spatial
Analysis (MSA) with the group and her research focuses on modelling chloride fluxes for the East Holland River watershed using INCA-Cl. Mallory's research is funded through an Environment Canada Lake Simcoe/Southeastern Georgian Bay Clean-Up Fund grant.
Undergradute Research Assistants
Alexis Robinson completed her Master of Spatial Analysis under the joint supervision of Claire Oswald and David Atkinson (Polar Seal Lab) in May 2016. Her thesis is entitled: Spatial and temporal modelling of current and predicted streamflow of a High Arctic watershed, Pond Inlet (Mittimatalik), NU. Alexis is now a PhD student at the University of Toronto.
