My research interests are in explaining the variation of mineralogical and geochemical properties in both natural and synthetic systems. My work is environmental in nature and has primarily focused on phyllosilicates, oxhyroxides, phosphates, metals and industrial minerals in sedimentary systems and geotechnologies. Current specific interests include development of defense related geotechnologies, mineralogical variation of shales in space and time, gold and native metal mineralization, rare earth element mineralization, urban pollution. I work extensively with graduate students and undergraduate student on numerous projects often involving transmission electron microscopy, scanning electron microscopy and bulk chemistry and field work. Current field areas are central Nevada, the Mexico-U.S. border, and the Midwest.
