Pharmacogenomics is the study of how an individual's genetic code affects the way the body responds to drugs. The field of pharmacogenomics is relatively new with the promise that medications can be tailor-made for each individual through a better understanding of the mechanisms underlying the genetic variability and its response to therapy. At Indiana University, there are many researchers who are doing pharmacogenomics research to better understand the relationship between genomics and drug response to improve the practice of medicine by enhancing the personalization of therapy.

The Indiana Institute for Personalized Medicine, in collaboration with the IU School of Medicine Department of Medical and Molecular Genetics, has developed a CLIA certified pharmacogenomics lab testing for clinical and research application.
