My research interests are in the characterization and regulation of microsomal monooxygenase enzymes (Cytochromes P450 and Flavin-Containing Monooxygenases) active in drug metabolism and their involvement in the detoxication and/or bioactivation of drugs, xenobiotics and endogenous compounds. In addition, a major focus of current research efforts is on diet and cancer. These studies employ both trout, mouse and human cell culture models to address mechanistic questions. Currently, we are working on a model that addresses the issue of maternal diet on cancer risk for the fetus in later life
