Pascal Badiou, Ph.D.

Research Scientist

Pascal Badiou joined IWWR in 2006. In general his research focuses on the ecology of wetlands and large shallow lakes. In particular, he’s interested in the role wetland restoration and conservation can play in regulating water quality and quantity in agricultural watersheds of the Canadian Prairies. He is also interested in how the interaction of multiple stressors such as invasive species, increased nutrient loading, pesticides and climate change affect wetland ecosystems.

Additionally, Pascal has been conducting research to determine the importance of wetlands in carbon cycling and how these systems can be managed to mitigate against climate change. He’s also interested in the use of constructed wetlands for the management of stormwater and treatment of sewage effluent to improve water quality at the watershed scale within urban environments.
