"Sarah Carmichael"Bio:
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, I currently focus on the geochemistry of Late Devonian mass extinctions, manganese geomicrobiology of cave deposits and wetlands, and the geochemistry of manganese ores in the Appalachians. As an Appalachian Studies faculty member, I focus on the environmental impacts and associated politics of energy extraction in Appalachia, from coal to natural gas to lithium to rare earth elements.
