Research themes: GHG exchange in managed and modified systems
Our primary interest is around the role that human activity has on the greenhouse gas exchange in ecosystems. We continue to examine ecosystems that have been modified directly through a land-use change or indirectly through climate change. We also are examining ecosystems that are managed for food production.

Our work with Hydro Quebec in the eastern James Bay boreal forest involved examining the net effect of a land-use change. Flooding the boreal forest to create a hydro-electric reservoir alters the net exchange of carbon and water with the atmosphere.
Our work with the Canadian Sphagnum Peat Moss Association at locations in Quebec and Alberta involves examining the net changes in carbon cycling resulting from drainage, peat extraction and restoration.
We are examining the controls on, and fate of, CO2 and CH4 from a temperate freshwater marsh that is part of the Mer Bleue wetland complex near Ottawa, Ontario.
Our collaborative work on Agricultural systems focuses on the movement of GHGs from various components of agroecosystems.
