The Polson Institute was established this year as a research-outreach facility within the Department of Rural Sociology in Cornell's New York State College of Agriculture and Life Sciences. The institute will promote theoretical and applied research activities related to worldwide development. It will focus on studying social movements, civil society and governance, inequalities and social exclusion, food and agricultural systems, gender and identity transformation, population changes, and community and environment issues.

Philip D. McMichael, Cornell professor and chair of the Department of Rural Sociology, serves as the interim director of the institute. David L. Brown, Cornell professor of rural sociology, will take office as director Sept. 21.

The institute was named for the late Cornell professor of rural sociology Robert Polson and his wife, the late Ruth Polson, Cornell B.S. '42, Ph.D. '51. Robert Polson's career teaching rural sociology at Cornell spanned more than four decades. Ruth Polson taught English and music at Ithaca High School.
