David A. Broniatowski is a Postdoctoral Fellow in the Center for Advanced Modeling in the Social, Behavioral, and Health Sciences in the Department of Emergency Medicine in Johns Hopkins University. His research integrates social and computer sciences to study group- and population-level behaviors. He actively collaborates with computer scientists, engineers, experimental psychologists, physicians, and sociologists in order to develop data-driven theories of risky decision-making and group behavior. In particular, his research examines how members of different social and demographic groups construct meaning in public health settings. He uses techniques ranging from natural language processing applied to social media and meeting transcripts, to more conventional survey and experimental designs to study the interactions between behavior and disease dynamics.
