Research: Igneous Petrology; Mantle Geochemistry; Role of Volatiles in Magmatic Processes; Deep Earth Geochemical Cycling of Volatiles
Dr. Dixon's research interests focus on the role of H2O and CO2 in the generation and evolution of basaltic magmas with an emphasis on submarine volcanoes. Her work includes solubility studies of H2O and CO2 in basaltic melts, vapor saturation and degassing models, and modeling of volatile contents in primary magmas and the mantle. Study areas have included the mid-ocean ridge system, Hawaii, the Galapagos, and the Easter Salas y Gomez Seamount Chain. Dr. Dixon received a NSF Early Career award in 1997 for excellence in research and education. In 2007, EPSL acknowledged one of her papers (Dixon et al., 2004) as one of their top-50 most cited articles.
From 1992 through 2010, Dr. Dixon was a professor at the University of Miami, where she was as a professor at the Rosenstiel School of Marine and Atmospheric Science and in the Geology Department within the College of Arts and Sciences. At UM, she served as Director of the Abess Center for Ecosystem Science and Policy's Undergraduate Program ('03-'08), Senior Associate Dean for the Life and Physical Sciences ('06-'10), and Interim Dean of the College of Arts and Sciences ('09-'10). Dr. Dixon became Dean of the College of Marine Science at USF in 2011. She currently serves on the Executive Board of the Consortium of Ocean Leadership.
