Dr. Ellen J. MacKenzie holds a joint appointment in emergency medicine and physical medicine and rehabilitation at the Johns Hopkins School of Medicine. She is the Fred and Julie Soper Professor, the Bloomberg Distinguished Professor and chair of the Department of Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health. She also holds a joint appointment in biostatistics at the Bloomberg School of Public Health.
An expert in health policy and management and biostatistics, Dr. MacKenzie serves on the faculty of the Johns Hopkins Center for Global Health, Center for Health Services and Outcomes Research and Center for Injury Research & Policy.
Dr. MacKenzie's research focuses on the impact of health services and policies on the short- and long-term consequences of traumatic injury. She has contributed to the development and evaluation of tools for measuring both the severity and outcome of injury, which have been used to evaluate the organization, financing and performance of trauma care and rehabilitation.
Her work has advanced the knowledge of the economic and social impact of injuries and our understanding of how personal and environmental factors influence recovery and return to work.
Most recently, Dr. MacKenzie has joined colleagues from around the country to establish the Major Extremity Trauma Research Consortium (METRC). The overall goal of METRC is to produce the evidence needed to establish treatment guidelines for the optimal care of the wounded warrior—and ultimately to improve outcomes of both service members and civilians who sustain high-energy trauma to the extremities.
An honorary fellow of the American Association for the Surgery of Trauma, Dr. MacKenzie was recognized in 2012 by the Centers for Disease Control and Prevention as one of 20 visionary leaders who have transformed the field of violence and injury prevention in the past two decades.
Her other professional honors include the A.J. Mirkin Service Award from the Association for the Advancement of Automotive Medicine; the Ann Doner Vaughan Kappa Delta Award from the American Academy of Orthopaedic Surgeons; the Distinguished Career Award from the American Public Health Association (Injury Control and Emergency Health Services Section); and the American Trauma Society's Distinguished Achievement Award.
Among her many national-level activities, Dr. MacKenzie has chaired the National Advisory Committee for Injury Prevention and Control and served as president of the American Trauma Society.
Dr. MacKenzie earned her Ph.D. and M.S. in biostatistics at the Bloomberg School of Public Health.
She joined the Johns Hopkins faculty in 1980.
