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. The geologic record provides unique opportunities to observe how natural systems respond to changing climate. We are especially interested in documenting the past responses -- and thereby estimating the future sensitivity -- of mountain glaciers, continent-sized ice sheets, and cold-adapted ecosystems to climate change. 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. For details, see my RESEARCH and PUBLICATIONS pages, my CV, lab news below, or this short VIDEO.

The Quaternary Sediment Lab hosts microscopy facilities and cold storage for sediment cores, and is equipped for geochemical, physical and paleoecological analyses of lake cores and other sediments.

for analysis in the Quaternary Sediment Lab.

My COURSES at Northwestern address Earth's climate system and climate history, methods in Quaternary geology, Earth surface processes, and the physical science of human impacts on the environment. For a taste of topics, read from students in my Energy & Climate Change class.

I am committed to sharing science beyond academia. For example, see my Op-Eds on cold winters and climate change and the future of the Arctic.
