My research focuses on assessing the impact of changing climatic conditions and industrial development on northern boreal-tundra freshwater landscapes in Canada. Water in these regions plays a central role in maintaining the ecological integrity of ecosystems, economic development and prosperity, and traditional use of the land and its resources by indigenous communities. However, insufficient knowledge of hydrological and ecological variability over space and time has historically impeded informed stewardship of water resources in these remote landscapes.
To fill this knowledge gap, my research integrates contemporary hydroecological studies spearheaded by the use of water isotope tracers with quantitative long-term (past centuries to millennia) records of hydroecological changes derived from analyses of lake sediment cores using state-of-the-art analytical techniques. The spatial and temporal insight gained from these approaches has been critical to inform stewardship of these important landscapes.
