My research examines how human activities drive ecological and biogeochemical change in aquatic ecosystems, including the use of lake sediment cores (the field of paleolimnology)to study recent aquatic ecosystem change over the context of the last several hundred years. I work in both temperate and high latitude regions throughout Canada, and currently have a strong focus in the Northwest Territories.
