News and publications
Over the past twenty years I have worked at the intersection of behavior change and informatics to develop and evaluate social network based interventions. While there is an emerging evidence base on how social networks impact behavior, less is known or understood about how they can be manipulated to create change. My work has demonstrated feasibility of the approach, demonstrating that networks can be characterized, that diffusion of interventions can be implemented, and that effective interventions can be created. I served as either the primary investigator or co-investigator on all of these studies.
