Research Statement

Dr. Hennessy’s primary field of interest is pharmacoepidemiology, which is the study of the use and effects of medications in populations. Within pharmacoepidemiology, he has a particular interest in studying the clinical importance of drug-drug interactions. Dr. Hennessy’s research has been funded by the Agency for Healthcare Research and Quality (AHRQ), the National Institutes of Health (NIH), pharmaceutical companies, and private foundations. He is currently leading a NIH-funded study on the clinical importance of drug-drug interactions. He is the principal investigator of Penn’s AHRQ-funded “Developing Evidence to Inform Decisions About Effectiveness” (DEcIDE) center, and of Penn's Center in the FDA-funded Scientific Program to Support Epidemiology Investigations.

In addition to his research, Dr. Hennessy teaches clinical epidemiology to medical and graduate students, and is active in promoting evidence based practice at Penn, directing its Ambulatory Drug Use and Effects Program, and serving on its Pharmacy and Therapeutics Committee. Dr. Hennessy’s clinical program has received two Quality and Safety Awards from the University of Pennsylvania Health System. Dr. Hennessy received the 2005 Young Alumnus Award from the University of the Sciences in Philadelphia, and the 2007 Lean I Goldberg Young Investigator Award from Pharmacology and Therapeutics.
