Research Focus

Toxicology, halogenated hydrocarbons, dioxin

My research is aimed at elucidating the mechanism of toxicity of chlorinated aromatic hydrocarbons (CAH) and related compounds. The cause of 2,3,7,8-tetrachlorodibenzo-r-dioxin-induced death in rats is a combination of appetite suppression and inhibition of gluconeogenesis, whereas in mice it appears to be inhibition of gluconeogenesis alone, leading to a lethal hypoglycemia. Currently three lines of research are being pursued: 1) elucidation of the molecular mechanism(s) of action leading to CAH-induced enzyme inhibition; 2) investigation of the subchronic and chronic toxicities of TCDD and its higher chlorinated homologues as well as other heterocyclic analogues such as chlorinated phenothiazines (CPT), and 3) studying female reproductive toxicity of both CAH and CPT.
