Patricia Tennis

Global Head of Epidemiology, RTI-HS

Patricia Tennis, PhD, came to RTI in 2002 from the pharmaceutical industry, where she helped design and implement drug safety studies and risk management activities related to use of medications. She has focused on drug safety, collaborating on studies of vaccine safety and on safety studies of medications in neurology, psychiatry, respiratory, and metabolic diseases. She has overseen numerous epidemiology studies and participated in regulatory discussions of drug safety issues with U.S., Canadian, and European agencies. Dr. Tennis has been the lead epidemiologist on studies that required implementation of a common protocol across multiple patient-centric databases, international pregnancy exposure registries, and projects to evaluate risk evaluation and minimization strategies. She is a leading researcher in pharmacoepidemiology and a fellow of the International Society for Pharmacoepidemiology.
