Dennis P. Culhane

Dr. Dennis P. Culhane is a leading thinker and researcher with primary expertise in the field of homelessness and assisted housing policy. He is considered 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. His work has influenced a national shift in how cities address homelessness and support the needs of people experiencing housing emergencies. His research includes studies of vulnerable youth and young adults, including those transitioning from foster care, juvenile justice, and residential treatment services. Dr. Culhane is the Director of Research for the National Center on Homelessness among Veterans at the United States Department of Veterans Affairs. He also co-directs the Intelligence for Social Policy initiative (ISP), a MacArthur-funded project to promote the development of integrated database systems by states and localities for policy analysis and systems reform.
