Biography

My research group conducts inter-disciplinary studies in geomatics (e.g. Geographic Information Systems and Remote Sensing), physical hydrology and the biogeosciences.  We focus on the spatio-temporal characterization and modelling of watershed ecosystems at sites throughout Canada’s northern ecozones, including the Boreal Shield, the Taiga Shield and the Arctic tundra, as well as more local sites in central Ontario and the Ottawa-Gatineau region. Some examples of specific topics include snow distribution mapping and modelling, mercury and trace-metal cycling, and wetland classification/hydrologic monitoring with satellite, airborne and UAV-based remote sensing.

I teach courses at all levels in the Department of Geography and Environmental studies, and supervise a team of graduate and undergraduate students. I also co-lead the recently funded Water and Ice Research Lab (WIRL) at Carleton, which specializes in field-data collection and geo-computation for water and ice research.  Finally, I work with government, industry, not-for-profit partners and community groups, and welcome new research opportunities and consultancies that fall within my broad areas of interest.
