Jay Zambito
Associate Professor of Geology, Beloit College
Jay’s research focuses on identifying and characterizing climatically-induced extinction events recorded in the Paleozoic rock record using a combination of paleontology, geochemistry, stratigraphy, sedimentology, and fluid inclusion analysis. His other interests include taphonomy (the process of fossil preservation) and paleontological curation. He has also studied the geochemistry and mineralogy of Cambrian-age frac sand deposits in Wisconsin in order to understand the potential environmental impacts of sand mining.
