Researchers and students interested in the connections between health, sociology, psychology, and epidemiology will want to explore Yale University's Human Nature Lab. Directed by social scientist and physician Nicholas Christakis, the lab takes an "interdisciplinary - or transdisciplinary approach to understanding human behavior." The Human Nature Lab is currently committed to exploring the relationships between social networks and health. On this website, visitors can learn more about the Lab's research and read publications. Research is organized into six major categories, which visitors can explore via the Research tab. These areas include the Biology of Social Interactions (an examination of the factors - including genetic and evolutionary factors - that inform why and how people form social networks); Experiments with Face-to-Face Networks (investigations of how personal interactions can influence health behaviors); and Network Methodology (which focuses on improving the interdisciplinary process of researching social networks). In addition, visitors to this webpage can read about previous research initiatives at the lab.
