Biography:

Since my first years at university, I have always been fascinated by the close links between geography and history. When I found out that we could study past environments and climatic conditions using natural indicators such as the growth rings in trees, it was like a bolt of lightning. Since that time, and throughout my career as a researcher, I have used the physical and geochemical characteristics of tree rings to reconstruct past climate conditions, study the dynamics of terrestrial processes, document the changes over time of anthropogenic contamination and study its impacts on the environment.

Research and/or project statements

Current Research Projects:

  • Development of biogeochemical indicators to follow the spatial-temporal evolution of forest ecosystems in the Northern Alberta oil sands region.
  • Impact of oil sands development on the nutrient regime and growth of forests in Northern Alberta.
  • Dendroisotopic reconstruction of hydroclimatic conditions of the last centuries in the boreal region of Canada.
