Research Interests I study sediments to reconstruct past climates and environments. The work is highly interdisciplinary because lake sediments result from complex biogeochemical interactions, plus the records have applications to many fields. My skill sets and research interests cross into the fields of physics, biology, chemistry, geography, and archaeology. I am particularly interested in varved sediments from glacial (annually deposited layers.) By studying glacial varves, we can learn how ice sheets responded to climate change on annual time scales. The study of glacial varves should be integrated with the study of glacial landforms, therefore my research interests have grown to include using ArcGIS.
