Dr. Carmichael is a geochemist who specializes in fluid-rock reactions in both ancient and modern environments. Her current research explores the paleogeographic controls on Late Devonian mass extinctions, fluid-rock reactions in carbonates, the geomicrobiology of cave mineral deposits and acid mine drainage sites, and the role of microbes in manganese ore formation.
Dr. Carmichael is also a member of the Appalachian Studies Faculty and teaches introductory, interdisciplinary, and advanced undergraduate classes and is the faculty mentor for first generation students in the GES department. She recently won a Board of Governors Teaching Award in 2020. In addition, she was named a Fellow of the Explorer's Club in 2016 and became a National Geographic Explorer in 2018.
