Sarah is a Professor of geology and Director of GeoFORCE Alaska, a field-based, summer geoscience program for rural Alaska high school students. She teaches undergraduate and graduate courses, including Historical Geology, Paleobiology, and Palynology. Her research involves identification of pollen and spores preserved in sediment cores in order to reconstruct past vegetation and climate. This summer, she’ll be collecting cores from the Bering Sea Shelf in search of sediment deposited in lakes and ponds on the Bering Land Bridge during the last ice age.
