Research Interests

Lake ecosystems are valuable natural resources, as well as important sentinels of environmental change. An important component of my research uses lake sediment cores as natural archives of long-term environmental change, since lake sediments integrate a variety of biological, physical, and chemical proxies into a stratigraphic profile that can be used to reconstruct past environmental conditions. This long-term perspective on environmental change can also provide insights into aquatic ecology and biogeography, as well as issues relating to lake management. This is especially true in regions where monitoring data are scarce, such as Canada's north, where I have been lucky enough to conduct much of my research over the past decade.
