Jeffrey G. Catalano

Assistant Professor
Ph.D. Stanford University, 2004

Environmental Geochemistry and Mineralogy

Professor Catalano studies the geochemistry of mineral-water interfaces and how these interfaces control the occurrence and speciation of elements in modern environments. Reactions occurring at mineral-water interfaces affect many processes important to and influenced by humans, including contaminant fate and transport, biogeochemical element cycling, ore deposit formation, biomineralization, and nuclear waste disposal. Professor Catalano combines laboratory-based analytical and microscopy tools with synchrotron-based X-ray spectroscopic and scattering methods to obtain a fundamental understanding of the nature of mineral-water interfaces and the reactions that occur here. Currently, Professor Catalano is investigating how water order on the surfaces of iron and aluminum oxides, how contaminant ions such as arsenic adsorb on these surfaces, and how ferrous iron can activate dynamic structural changes of iron oxide surfaces.
