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.

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.
Dwayne 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.

Michelle's 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.
Kayla completed her B.Sc. at McMaster University where her research focused on the influence of tree harvesting techniques on soil respiration rates. Kayla's current research uses isotopes to explore the downstream impact of stormwater control measures on urban stream hydrology.
Wai Ying Lam joins the group from McMaster, where her undergraduate research focused on freshwater ecology and biomonitoring tools. Wai is working on her Masters in EnSciMan, examining the impacts of stormwater control measures on stream biogeochemistry and ecological function.
Ela's research focuses on developing an automated approach to identify and map impervious areas in the highly urbanized Black Creek watershed using high resolution aerial imagery and LiDAR data.
Krystal research focuses on understanding the relationship between hydrologic connectivity metrics within a watershed and mercury concentrations in fish, throughout Ontario.

Arsh is interested in studying the effects of near shore vegetation using remote sensing on Innisfil Creek. He also assists the group with fieldwork and is an excellent swimmer.
Doug 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.
EUS; 2016-2017; undergraduate research assistant
Sammy is in her fourth year of the Environment and Urban Sustainability (EUS) program and working as an Undergraduate Research Assistant. Sammy assists the group in the field and lab, collecting and filtering water samples, preparing, organizing data and assisting where needed. She also is behind capturing the work that is happening through photos.
September 2016-August 2017; research technician; now a Water Resources Technician with Hatfield Consultants in Ft. McMurray
Felix Chan worked as a research technician for the group from September 2016 to August 2017. He was primarily responsible for establishing the field program and protocols for the Innisfil Creek water quality monitoring project. Felix is now working for Hatfield Consultants as a Water Resources Technician in Fort McMurray.
Mallory's research focused on modelling chloride fluxes for the East Holland River watershed using INCA-Cl. Mallory's research was funded through an Environment Canada Lake Simcoe/Southeastern Georgian Bay Clean-Up Fund grant.
