Research Interests:

My interests involve reactive fluid flow and mineralization in sedimentary and volcanic systems in both ancient and modern environments, as well as microbially mediated reactions at the Earth's surface. As a National Geographic Explorer and one of the Explorers Club 50, my fieldwork focuses on the geochemistry of Late Devonian mass extinctions, manganese geomicrobiology of cave deposits and wetlands, and the geochemistry of manganese ores in the Appalachians. My laboratory work associated with these projects involves the analysis of micron-scale mineral textures and the interplay between microbes and minerals. As an Appalachian Studies faculty member, I teach about the environmental impacts and associated politics of energy extraction in Appalachia, from coal to natural gas to lithium to rare earth elements.

If you are looking for MS/PhD/Postdoc opportunities: Appalachian State University's Department of Geological and Environmental Sciences is an undergraduate-only program, and does not have positions for graduate students or postdoctoral scholars. However, I can act as a committee member for MS and PhD students at other universities, if the university allows external faculty to serve on thesis committees.

  • If you are interested in graduate work with the manganese geomicrobiology research team, you must have a background in microbiology and apply to the MS in Biology program. Please contact Dr. Suzanna Bräuer in the Department of Biology for more information.

  • If you are looking for a postdoctoral fellowship or visiting researcher position, at this time I am only able to accommodate those from universities which already have an international exchange agreement with Appalachian State University.
