Overview of Research :

My broad research interests are on the chemistry and fate of inorganic contaminants in the environment. My specific interests are in the development and application of hyphenated techniques, with ICP-MS as an element specific detector, to study the spatial distribution, size fractionation and chemical speciation of trace elements in environmental or biological media. Techniques used included: Laser ablation-ICP-MS to study elemental spatial distribution at the micron scale, field flow fractionation-ICP-MS to study metal interactions with soil and sediment colloids, size exclusion chromatography-ICP-MS to study metal-humic interactions in surface and groundwaters and metal-biomolecule interactions in tissue extracts, and ion chromatography-ICP-MS to study arsenic and selenium speciation in environmental and biological samples.
