Dennis Culhane is the Dana and Andrew Stone Professor of Social Policy at the School of Social Policy and Practice at the University of Pennsylvania. He is a nationally recognized social science researcher with primary expertise in the field of homelessness. Dennis is a leader in the integration of administrative data for research and directs the Actionable Intelligence for Social Policy (AISP) initiative, a MacArthur-funded project to promote the development of integrated database systems by state and local governments for policy analysis and systems reform. He is an early innovator in the use of administrative data for research and policy analysis, particularly for populations and programs which are difficult to assess and track. His work resulted in federal legislation requiring all cities and states to develop administrative data systems for tracking homelessness services in order to receive HUD funding. Culhane’s current work with colleagues in New York City, Boston, and Los Angeles County analyzed healthcare utilization and long-term care use by individuals who are aged 55 or over and experiencing homelessness.
