Ben Cornwell is associate professor of sociology at Cornell University, where he teaches introduction to sociology, the sociology of disasters, and research methods. Professor Cornwell's research interests include sociology of health and aging, social network analysis, organizational sociology, and social stratification. His current research focuses on the implications of socially networked and sequenced social processes for individuals and organizations--and, in particular, how such processes shape social stratification. His most recent work on social sequence analysis demonstrates how the ordering of social phenomena affects a variety of phenomena, including the stress process and the creation of social networks.
