I study climate and environmental change, primarily through the lens of paleolimnology (the study of lake sediments and past lake environments). My current work is aimed at 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 my research has focused on the Holocene (the past 11,000 years of Earth's history), but I study timescales ranging from the Pliocene to the present.

**NEWS** Construction of Northwestern's new Quaternary Sediment Lab was completed in November 2012. The 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. Instruments for elemental analysis, spectrophotometry, and magnetic susceptibility measurements are on the way.
