I obtained a Ph.D. in aqueous and sedimentary low-temperature geochemistry from Michgan State University in 1989. My dissertation was on the geochemistry and evolution of Michigan Basin brines. I have considerable experience with groundwater and surface water geochemistry of major ion and trace metal including numerical modeling of speciation and transport, and analytic methods. I have been with the USGS since 1994 and have been involved with projects that include bio-remediation and air-sparging of chlorinated hydrocarbons in groundwater; evaluating loads of dioxins, PCB, pesticides and other organic and inorganic compounds in the tributaries to Newark and Raritan Bays; mercury and arsenic in soils, rivers, and lakes; , pesticides in human wastes and waste water treatment effluent; and most recently, nutrient and sediment fluxes in Barnegat Bay, NJ.
