Postdoctoral training with emphasis on human metabolism of environmental chemicals and identification of human population at risk in the laboratory of Dr. Ernest Hodgson, North Carolina State University, Raleigh, North Carolina, 2005-2008.
My research of interest involves the development of in vitro system to study xenobiotic metabolism of humans and animals using biochemical technology and their application to safety and risk assessment of environmental chemicals. The central goal of these efforts is to develop reliable methods for in vitro to in vivo extrapolation using human biological values and reducing our dependence on laboratory animals in toxicity testing. Current research efforts are focused on the qualitative/quantitative measurement of all of the phase I and phase II metabolic products of phthalate and parabens with varying tissue fractions of human and laboratory animal, recombinant drug metabolizing enzymes (DMEs) and primary cell systems.
