Dr. Trepanier's research focuses on indiviudal or breed differences in xenobiotic detoxification, and their effects on the risk of drug toxicity or carcinogenesis. The laboratory's current area of research is the interaction between genetic variants in gluthathione-S-transferases, household environmental exposures, and cancer risk in dogs. She has recently studied mechanisms of idiosyncratic drug toxicity, and has ongoing studies of biomarkers of oxidative stress in dogs and cats.
