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. Culhane is a nationally recognized social science researcher with primary expertise in the field of homelessness. He 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. His homelessness work has positioned him as an early innovator in the use of administrative data for research and policy analysis, particularly for populations and program impacts which are difficult to assess and track. Culhane’s work has resulted in federal legislation requiring all cities and states to develop administrative data systems for tracking homeless services in order to receive HUD funding. Culhane’s currently working with colleagues in New York City, Boston, and Los Angeles County to conduct a multi-site data-based analysis of health care utilization and long-term care use by individuals who are aged 55 or over and experiencing homelessness.
