CURRENT S&T / RESEARCH - Conduct research on the impact of anthropogenic stressors on biodiversity of aquatic ecosystems

  • Analysis of hydro-climatic factors on biodiversity and the functioning of animal communities in fluvial environments
  • Functional relationship between diversity and productivity of fish assemblages in fluvial environments
  • Analysis of the impacts of alien invasive species on aquatic freshwater ecosystems
  • Distribution, recruitment and colonization of alien species in fluvial environments
  • Environmental and toxicological evaluation of ballast water treatment methods


Aquatic ecology of rivers and estuaries and the effects of physical factors on variations in the diversity and abundance of aquatic fauna

Ecology and impact of introduced species in fluvial environments and the effectiveness of control methods to reduce the risk of species introductions and transfers

Co-chair of the "Water Quality Improvement" committee of the St.Lawrence Action Plan (2011-2016)
