His research program is part of an emerging field in the social sciences aimed at connecting micro-level local dynamics (e.g., social influence) with large-scale social phenomena (e.g., the emergence of collective memories). Using experimental methods in conjunction with computer simulations and social network analysis, this research program is aimed at investigating complex social, cultural, and political phenomena. Research from his lab has revealed how selective media coverage has deleterious consequences on people's knowledge about diseases, how socio-cognitive processes triggered in dyadic interactions lead to the formation of shared memories, and how information propagation in social networks affects the emergence of collective memories in small-scale networks.
