Our lab takes an interdisciplinary "Communication Neuroscience" approach to link neural activity to behaviors at the individual, group and population levels. Specific lines of work in the lab include predicting behavior change following exposure to persuasive messages and understanding what makes successful ideas spread (e.g. through social networks, through cultures). At present, much of the research in our lab focuses on health communication, and the design of better interventions, programs and policies. Recent work explores neural predictors of increased sunscreen use, neural predictors of tobacco cessation, and links neural responses to health messages to population level behavioral outcomes; other areas of interest include political communication, cross-cultural communication, and the spread of culture, social norms and sticky ideas.
