    Drew Muscente

    Assistant Professor of Geology

    Drew teaches introductory and advanced courses in sedimentary (“soft rock”) geology. He and his students study the fossil record to better understand the evolution and preservation of ancient marine animal life. This research involves a mix of field and laboratory work on fossil specimens as well as an array of computational methods applied to large databases.

    Emily Walsh

    Associate Professor of Geology

    Teaches courses that include Mineralogy, The Origin of Mountains, and the off-campus course Geology of the National Parks. She has also co-led Greek Archaeology in Greece. Her research focuses on the formation of mountain ranges and the mechanisms involved in subduction zones. In particular, she and her students study the metamorphic reactions, geochronology, and deformation of ultrahigh-pressure rocks from Western Norway to better understand the tectonic history of the Scandinavian Caledonides. Ph.D., University of California at Santa Barbara; B.A., Middlebury College.
