Genetic influences on medication outcomes in psychiatry and cardiovascular medicine

Pharmacogenetics – the influence of genetic variability on medication outcomes – is an aspect of precision medicine. Genetic variability can affect efficacy, tolerability, and dose requirement. For several medications, the evidence for pharmacogenetic influence on outcomes is sufficient for routine use in clinical practice. My research program seeks to appropriately use these established associations to tailor treatment, and to identify new associations that could be used in the future. I have a particular interest in psychiatric medications and cardiovascular medications.
