Earth & Environmental Systems Lecture Series presents Sheri Fritz

Earth & Environmental Systems Lecture Series presents Dr. Sheri Fritz, University of Nebraska-Lincoln Department of Earth & Environmental Systems. Dr. Aldrich will present "The Cenozoic evolution of biotic and geophysical diversity in the tropical Andes and Amazon."

Sheri’s interests lie at the interface of geological, ecological, and atmospheric sciences and focus specifically on the interaction of lakes with the atmosphere and the land surface, both in contemporary times and during the Quaternary. She specializes in the application of diatom analysis to questions of environmental change, although her current projects complement diatom-based reconstructions with geochemical and geomorphic approaches. Her research also combines studies of lacustrine stratigraphic records with descriptive and experimental studies of modern lakes as models for interpretation of fossil sequences. Her current research projects focus on long-term hydrologic variability in tropical South America and in the Great Plains and Rocky Mountain regions of North America.
