LYLE FEARNLEY lives and works in Tianjin, China. He received a Bachelors degree in Anthropology from Columbia University in 2005. Currently, his work focuses on the development of syndromic surveillance, a technology designed to detect emerging epidemics without relying on diagnostic reports, which has emerged as a site where security and health practices are under re-formation. His research combines inquiry into the history of disease surveillance in the United States with contemporary investigations, including ethnographic work among syndromic experts in local health departments.
