Scott Frickel is professor of sociology and environment and society at Brown University and community engagement core leader for the Brown University Superfund Research Program. He is also founding editor of the Nature, Society and Culture book series at Rutgers University Press. A recipient of grants from the National Science Foundation and National Institutes of Health, his research and teaching interests focus mainly on intersections of nature, knowledge, and politics. He has published five books, the most recent with Jim Elliott, a study of chemical hazards, changing land use patterns, and environmental inequality called Sites Unseen (Russell Sage Foundation). Two new book projects currently capture most of his attention. One examines the residual nature of environmental chemicals in relation to regulation, health, and social theory. The second book investigates the complicated relationship between science and inequality.
