David Broniatowski, Ph.D., Director of the Decision Making and Systems Architecture Laboratory, conducts research in decision making under risk, group decision making, system architecture, and behavioral epidemiology. This research program draws upon a wide range of techniques including formal mathematical modeling, experimental design, automated text analysis and natural language processing, social and technical network analysis, and big data. Current projects include a text network analysis of transcripts from the US Food and Drug Administration's Circulatory Systems Advisory Panel meetings, a mathematical formalization of Fuzzy Trace Theory -- a leading theory of decision-making under risk, derivation of metrics for flexibility and controllability for complex engineered socio-technical systems, and using Twitter data to conduct surveillance of influenza infection and the resulting social response. Dr. Broniatowski was recently awarded a large prestigious grant ($1.55m) by the National Institutes of Health for his work on vaccination and big-data mining. His work has been widely reported in both local and national media sources, including Slate.com, The Daily Beast, New York Magazine, The Washington Post, CBS, and Men's Health.
