Dr. Barth is a glacial geologist and paleoclimatologist. His research explores geological and climatological questions through a multifaceted approach using methods related to geochronology, geomorphology, sedimentology, and field mapping. He focuses on Quaternary geology as it relates to climate change and the reconstruction of the glacial histories of multiple regions through surface exposure dating of boulders deposited by ice sheets, glaciers, and outburst floods of ice-dammed lakes. Broadly his lab aims to understand how climatologically important bodies of ice on Earth changed and behaved in the past so that we might better predict how similar features might change in the future.
