My students and I study climate and environmental change, primarily through the lens of paleolimnology (the study of lake sediments and past lake environments). Our field and laboratory work focuses on understanding the impacts of climate change in Arctic and alpine environments. Periods of past climate change provide opportunities to observe -- via the geologic record -- how natural systems including ecosystems and glaciers tend to respond to changing climate. Much of the research in my lab has focused on the Holocene (the past 11,000 years of Earth's history), but we study timescales ranging from the Pliocene to the present.
