In the Environmental and Aquatic Biogeochemistry Laboratory we conduct research to understand the impacts of environmental stressors such as contaminants, nutrients, and climate change on aquatic ecosystems, focusing primarily on the Arctic and Boreal ecoregions. A biogeochemical perspective is required because many environmental problems, including heavy metal pollution, eutrophication and climate change, are caused by anthropogenic disturbances to natural biogeochemical cycles. Our research is interdisciplinary - integrating physical geography, environmental chemistry, limnology and ecology - and combines emerging analytical techniques, ecosystem-scale field studies and controlled experiments to elucidate how humans impact the natural world we live in.
