James Moody is Robert O. Keohane Professor of Sociology at Duke University. His research focuses on social networks in multiple contexts. These include friendships among adolescents, the correspondence between social networks and neighborhood, the spread of sexually transmitted diseases, and social relations on the Internet. Moody is interested in extending network techniques to large-scale social networks (1000s of nodes), which includes developing efficient methods for sampling networks and identifying how social networks change over time. Moody also directs the Duke Network Analysis Center.
