Learn MoreDennis P. Culhane
Dr. Dennis Culhane is a Professor at the University of Pennsylvania, where he is also the Dana and Andrew Stone Chair in Social Policy and Co-Principal Investigator for Actionable Intelligence for Social Policy. Dennis also serves as Director of Research for the National Center for Homelessness Among Veterans at the U.S. Department of Veterans Affairs.
Dennis’ primary area of research is on the use of data to understand the nature of homelessness and design cost-efficient policy approaches to serving individuals and families experiencing homelessness. His work in this area 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. Dennis’ 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. His work has also been instrumental in a national shift in how cities address chronic homelessness and family homelessness.
Dennis’ recent research includes studies of vulnerable youth and young adults, including those transitioning from foster care, juvenile justice, and residential treatment services. For the past 15 years, he has also served as Co-Principal Investigator, with Dr. Jill Khadduri, of the Annual Homeless Assessment Report to Congress. Together with Dr. Cortes, he is leading efforts to develop a DataHub that will make data on homelessness more accessible and useful to practitioners.

Learn MoreMarybeth Shinn
As a professor at Vanderbilt University, Dr. Marybeth (Beth) Shinn focuses on ways to prevent and end homelessness and create opportunities for groups that face social exclusion.
She is co-principal investigator of the Family Options Study, a 12-site experiment comparing the success of different strategies to house families experiencing homelessness. Conducted together with colleagues at Abt Associates, the study followed 2,300 families for three years to understand how the strategies affected housing stability, self-sufficiency, family preservation, and adult and child well-being. Beth and students also analyzed qualitative interviews with 80 of the families across four study sites to understand families’ experiences in the homeless service system, how they make housing decisions, and why so many parents become separated from their children.
One of Beth’s particular areas of expertise is developing tools to predict who among populations in deep poverty and experiencing various forms of psycho-social distress will become homeless. With her students, she has developed targeting models to help New York City direct homeless prevention services available through the HomeBase program to the people most likely to become homeless without them. With colleagues at the Urban Institute, she is also studying whether supported housing can avert child out-of-home placement among families where homelessness contributes to risk.
Past collaborations with community organizations and research institutes include an experimental study of the Pathways Housing First intervention with adults who experience both chronic homelessness and serious mental illness, a survey of older adults in poverty to understand why some become homeless, an evaluation of New York City’s street count, and an experiment to determine whether rapid re-housing with transitional services fostered positive outcomes for children who were homeless with their families.
