Informatics Research Seminar: Networks Diffusion and Health, Open Problems

November 13 @ 4:00 – 5:00 pm


Speaker: James Moody, PhD
Presented from Duke University


This presentation examines how health & health behavior are shaped by social networks. In the last 20 years, there has been a dramatic rise in “network science,” characterized by the recognition that many fields use similar graph-based tools and aimed at leveraging these tools for cross-disciplinary gain. Here, I examine how network tools contribute to our understanding of health behavior, focusing on diffusion problems (spread of sexually transmitted diseases, for example, but also peer norms affecting behavior). This survey suggests that, while promising, there is still much work to be done and I lay out a set of strategies for future work.


Professor James Moody teaches in the Department of Sociology at Duke University.  Dr. Moody’s research focuses on the structural dynamics of social networks. The substantive contexts of his work range widely, from adolescent social network structure to the spread of HIV/AIDs. His current projects include a book on the visual history of social networks, collaborations on the dynamics of youth networks, and mapping the dynamics of science networks.
