Research Interests

Current research interests include the development of quantitative methods for the analysis of pharmaceuticals, personal care products, and nanomaterials in foods and environmentally relevant samples.   Of particular interest is the interaction and effect of food components (such as polyphenolics or similar antioxidants) on the stability and bioavailability of such environmental pollutants.
