Dr. Blanton Johansen is a Professor of Biology and PI in the Center of Excellence for Field Biology. Her research interests include the systematics, biogeography, evolution, and conservation, of freshwater fishes and crayfishes. She received her Ph.D. from Tulane University and M.S. from Eastern Kentucky University. She also serves as the Curator of Fishes in the David Snyder Museum of Zoology.
