Director, Center on Housing and Homelessness
Sarah B. Hunter (she/her) is a senior behavioral scientist, professor at the Pardee RAND Graduate School and director of the RAND Center on Housing and Homelessness (CHHLA). Over a decade ago, Sarah started working in the field of supportive housing. Since that time, she has led numerous studies documenting the impact of supportive housing on service use and associated costs, including initiatives in Los Angeles County (i.e., Housing for Health and Just in Reach Pay for Success) and beyond (e.g., in the Inland Empire and Pima County, AZ). She has also studied programs that provide rapid-re-housing and employment supports for people involved in the justice system. She recently co-led a longitudinal study of veterans experiencing homelessness in West Los Angeles to better understand service utilization and barriers to housing stability. She currently helps direct several of the Center projects, including research to better understand the needs and preferences of transitional aged youth and unsheltered adults experiencing homelessness. Hunter is active in the Homelessness Policy Research Institute, a joint effort by University of Southern California, United Way Greater LA, and the Conrad N. Hilton Foundation. Hunter received her B.A. from New York University and her M.A. and Ph.D. from the University of California at Santa Barbara.
