Research Interests:Drug hypersensitivity. Drug and carcinogen detoxification. Pharmacogenetics.


 Dr. Trepanier’s research is on genetically determined differences in drug biotransformation and their effects on the individual risk of drug toxicity or cancer outcomes. The major focus of her laboratory is on the mechanisms of risk for sulfonamide drug hypersensitivity reactions in immunocompetent and HIV-infected patients.
