Current Students

Mara Cloutier '16 - Master's Thesis (Biology)

Mara is culturing and sequencing biomineralizing fungal and bacterial populations in southern Appalachian caves in an attempt to determine the geochemical constraints on the enzymes that may control Mn oxidation, particularly multicopper oxidase.
co-advised with Dr. Suzanna Bräuer

Cameron Batchelor '15 - Senior Thesis

Cameron is working on a geochemical study of the Late Devonian mass extinction, using 87Sr/86Sr measurements to provide information about depositional setting and diagenesis, and looking for zircons in sediments to help constrain biostratigraphic ages. When she is not on the scanning electron microscope at Appalachian, she is working in the Geochronology and Isotope Geochemistry lab run by Dr. Drew Coleman at UNC-Chapel Hill.
co-advised with Dr. Johnny Waters

John Granholm '18 - Independent Study

John is trying to decipher the causes and mechanisms of microbialite formation in Late Devonian sediments from Mongolia.
co-advised with Dr. Johnny Waters

Kieran Krommes '18 - Independent Study

Kieran will be working on sediments that encompass the Late Devonian Hangenberg Anoxia Event in Vietnam to better understand their tectonic significance as well as the severity of anoxia.
co-advised with Dr. Johnny Waters

Travis Hartney '16 - Independent Study

Travis is attempting to characterize vocanic clasts from Oldonyo Lengai in Tanzania to map the extent and direction of mudflows at the Engare Sero early hominid footprint site.

Benjy Strauss '16 - Independent Study

Benjy is working on mapping garnets and magnetite inclusions in hydrothermally altered ultramafic rocks in the Ashe Metamorphic Suite in the southern Appalachians.

Robert Thomas '17 - Independent Study

Robert is working on a project to determine the uplift timing of CAOB sediments in Mongolia using apatite fission track dating.
co-advised with Dr. Gabe Casale
