Biographical Sketch

Dr. Markowitz has been credentialed by the Board of Pharmaceutical Specialties in Psychiatric Pharmacy since 1997. Following his training, Dr. Markowitz served for a number of years as a hospital-based Clinical Specialist in Psychiatry within the Institute of Psychiatry at the Medical University of South Carolina (MUSC) in Charleston, South Carolina. He eventually entered into a primary faculty research position in the MUSC College of Pharmacy’s Department of Pharmaceutical & Biomedical Sciences with a dual appointment in the Department of Psychiatry and Behavioral Sciences where he had remained prior to joining UF in 2009.

Research Interests

  • Dr. Markowitz’s research program has encompassed both in vitro and in vivo investigations including normal volunteer pharmacokinetic studies directed at the assessment of drug-drug interactions in psychopharmacology, botanical-drug interactions, as well as their associated clinical effects. More recently, the research program has focused on variability in drug metabolism, disposition, and therapeutic response as a consequence of genetic variability which influences both drug transporters and hepatic enzymes. He has received research support from both the pharmaceutical industry and the National Institutes of Health.
