Dena Bravata is a practicing internist and a CHP/PCOR research associate. Her research expertise is primarily in the development of methods for the synthesis of medical evidence, such as systematic reviews and meta-analysis. In past work, she has performed comprehensive meta-analyses of the safety and efficacy of low carbohydrate diets; of the quality of life, employment, and alcohol use among liver transplant recipients; and of the differences between dermatologists and primary care physicians in their ability to accurately diagnose melanoma. Over the past several years, she has been an active contributor to the Stanford-UCSF Evidence-based Practice Center's efforts to synthesize evidence related to bioterrorism preparedness. In this capacity, she recently directed a project to prepare a comprehensive evidence report on the regionalization of services for bioterrorism preparedness and response. She received a BS in biology from Yale University and an MD from Columbia University. At Stanford she completed a residency in internal medicine and earned an MS in health research and policy.
