Dr. John Ezell is an Assistant Clinical Professor in the Department of Geosciences at Mississippi State University (MSU). He obtained his PhD in 2016 in Geology. His research background includes hydrology, biogeochemistry, and karst. He has conducted research at field sites in several southeastern US states, the Gulf of Mexico, and The Bahamas. Dr. Ezell’s research projects have included herbicide research, soil moisture studies, measuring and modeling geochemical responses to hypoxia in bay waters, geochemical changes in karst springs during spring reversals, and tidal influences on the biogeochemistry of Bahamian blueholes, and karst landscape evolution. He has taught geoscience courses for more than a decade and is currently working on improving distance learning course structures.
