Recent research has been directed at understanding sources, transport and transformations of fluorotelomer and perfluorinated compounds in the environment using LC/MS/MS and GC/MS.
Past research areas include: 1) characterizing redox potential and controls on electron-exchange reactions in environmental systems; 2) controls on mobility and transformations of agricultural nutrients, especially nitrogen; 3) quantifying thermodynamic properties and hydrolysis rates of volatile organic compounds as well as analytical modeling of these compounds in the environment; and 4) elucidating geochemical controls on the concentrations and distribution of radionuclides and metals in the environment. Analytically, this research entailed ion and gas chromatography, spectrometric, fluorescence and phosphorescence detectors, as well as other conventional analytical methods.
