Before coming to Carleton, I studied geography and biology at Queen’s University at Kingston, and geography and environmental studies at the University of Toronto. I was a faculty member at the University of Toronto for one year, and worked on several research projects there in addition to my doctoral studies. In 2003 I joined Carleton University and the Department of Geography and Environmental Studies.
I am a co-director of Carleton’s Geomatics and Landscape Ecology Laboratory, and most of the graduate students I work with are based in that facility. We work on a range of projects analyzing and developing analysis tools for impacts of spatial patterns on environmental processes. Some more specific research projects include:
- the role of spatial and temporal heterogeneity in farmland on regional biodiversity; we first studied this in eastern Ontario, and our approach has been replicated in various locations in Europe. See http://www.farmland-biodiversity.org/index.php?sujet=1&lang=en. Our official (funded) projects are now over but the resulting database still fuels fascinating projects;
- primary productivity patterns in agricultural areas, including natural grasslands, under contemporary conditions and climate change or alternative management scenarios;
- impacts of alternative climate scenarios, especially with respect to changes to extreme weather, on Ontario’s agricultural sector. A lot of my current research effort is to further develop and demonstrate the potential of crop-specific extreme weather indices, and a spatial scenario modelling framework to study this.
