Research Interests

  • Cardiovascular Pharmacotherapy
  • Pharmacogenomics
  • Pharmacodynamics and Pharmacokinetics
  • Drug Metabolism

Research Projects

My research interests are focused on optimizing the use of therapeutic agents used for the prevention and treatment of cardiovascular disease by investigating pharmacogenetic, pharmacokinetic and pharmacodynamic sources of variability in response. Although primarily interested in cardiovascular Therapeutics (eg the GOLDN Study), my investigations have included environmental sources of variability in response as well as therapeutic agents used to treat conditions other than cardiovascular disease. We are also interested in research related to ethnicity-based sources of drug response variability. Understanding sources of variability in drug response may prove helpful in optimizing the achievement of therapeutic targets - a goal which is common to all those interested in optimizing clinical outcomes.
