Paul J. Ferraro is the Bloomberg Distinguished Professor of Human Behavior and Public Policy at Johns Hopkins University. Dr. Ferraro has a joint faculty appointment in the Carey Business School and the Department of Environmental Health and Engineering, a joint department of the Bloomberg School of Public Health and the Whiting School of Engineering. Ferraro’s research focuses on building a credible evidence base about the environmental and social impacts of public and private programs. Combining the approaches of epidemiologists, with their naturally occurring data, and clinical trial health scientists, with their randomized controlled trials, Ferraro seeks to identify the causal links between the actions we take to improve our world and the impacts of those actions. He also has broad interests in behavioral science and causal inference. Because these research areas are multi-disciplinary and applied, he collaborates with scientists and engineers from a variety of social, natural and physical science disciplines, as well as practitioners in the field.
