Our laboratory explores the fate of contaminants in temperate and polar ecosystems in order to better predict their mobility and toxicity. Microbes exhibit tremendous and fascinating metabolic diversity. As such, we use them as sentinels of environmental perturbations and aim at a better understanding of their role as actors shaping the environment around us. Our current research topics focus on mercury (Hg), a potential potent neurotoxin, and iron (Fe), a key element in cellular and geochemical processes.
