John V. Walther, professor of Earth Sciences and the Clifford W. Matthews Chair in Earth Sciences, joined the SMU faculty in 1994. He earned a B.A. from Oberlin College and M.S. and Ph.D. degrees from the University of California-Berkeley. Professor Walther's research focuses on experimental as well as theoretical aqueous geochemistry. In particular, he has considered fluid-mineral surface interactions, kinetics of mineral dissolution, and mineral solubility as a function of temperature, pressure and solution composition. In addition to more than 60 publications in refereed journals, he wrote two textbooks: Earth's Natural Resources (2014) and Essentials of Geochemistry (2005, 2009). Professor Walther also co-edited Fluid-Rock Interactions During Metamorphism (1986). He served as the director of SMU's Environmental Science/Studies programs from 2010-2016. Prior to SMU, he was the founding director of Northwestern University's Environmental Science major program, also serving as professor and chair of its Department of Geological Sciences as well as a J. Willard Gibbs instructor at Yale University. Professor Walther retires as Professor Emeritus of Earth Sciences.
