Our research is on the structure and function of networks, particularly social and information networks, which we study using a combination of empirical methods, analysis, and computer simulation. Among other things, we have investigated scientific coauthorship networks, citation networks, email networks, friendship networks, epidemiological contact networks, and animal social networks; we have studied fundamental network properties such as degree distributions, centrality measures, assortative mixing, vertex similarity, and community structure; and we have made analytic or computer models of disease propagation, friendship formation, the spread of computer viruses, the Internet, and network navigation algorithms.
