Jim came to Beloit College in 2002 from the National Museum of Natural History at the Smithsonian Institution where he was a Post Doctoral Fellow. Jim's teaching interests include physical geology, mineralogy, and petrology.  His research incorporates petrology and geochemistry to learn about the role of fluids in the Earth's crust in both metamorphic and low-T environments.

Professor of Geology and Department Chair
Weeks Chair in Physical and Human Geography
Chair of Natural Sciences

BA, Gustavus Adolphus College; MS (Geology), MS (Water Resources Management), PhD, University of Wisconsin-Madison
phone: 608-363-2132, fax: 608-363-2052

Prior to joining the faculty in 2001, Sue worked in the environmental consulting industry and at the Wisconsin Geological and Natural History Survey. She also spent two years in the Peace Corps teaching high school math and science in Lesotho, southern Africa. Sue's teaching interests include environmental geology, hydrogeology, geomorphology, and geographic information systems (GIS).  Her research interests include wetlands hydrogeology, spring flow, and heterogeneities in sedimentary bedrock aquifers. She also has interests in the effects of urbanization on surface water and groundwater resources. In Fall 2007, Sue directed the Associated Colleges of the Midwest Ecology and Human Origins program in Tanzania.

Jay ZambitoJay Zambito

Associate Professor of Geology
BS, SUNY College at Brockport; MS, SUNY University at Buffalo; PhD, University of Cincinnati
phone: 608-363-2223, fax: 608-363-2052

Jay began at Beloit College in 2018, after spending five years as a Research Professor at the Wisconsin Geological and Natural History Survey, University of Wisconsin. His teaching interests include Earth and life history, paleoclimatology, stratigraphy, and ancient environments. Jay's research focuses on identifying and characterizing climatically-induced extinction events recorded in the Paleozoic rock record. 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.
