Professor Cornwell's research focuses mainly on social networks among individuals and organizations. Most of his work explores the implications of these networks for individual and organizational outcomes, the production of social capital, and the reproduction of social stratification. He has documented the importance of integration in social networks for individuals' health, social influence, and employment, as well as the reciprocal effects of health and life-course experiences on the ability to achieve and maintain powerful positions within networks. He has also explored the indirect impact individuals' networks have on the influence and success of the larger organizations (e.g., unions) to which they belong. Some of his recent work in economic sociology explores the link between state unemployment rates and the statewide diffusion of influenza, the influence of individuals’ labor force status and workers’ nonstandard work schedules on daily rates of social contact, and the role of voluntary association networks in augmenting cohesion among community elites.
