Dr. Graham J. Pruss uses mixed-methods to study direct outreach, social services and public policy development regarding unhoused and displaced communities, specifically vehicle residents. Graham joined the Benioff Homelessness and Housing Initiative at the University of California San Francisco’s Center for Vulnerable Populations as a Postdoctoral Scholar in 2020, after receiving his PhD from the University of Washington Department of Anthropology. Dr. Pruss brings diverse perspectives to anthropological and ethno-archaeological research in these topics, as a former social service outreach specialist for vehicle residents (2013-2015) and previous recipient of social welfare programs as a homeless youth and teen parent in the early 1990s. He directed the Vehicular Residency Research Program (VRRP) at Seattle University from 2012 to 2013, where field researchers mapped anonymous vehicle residence settlement patterns correlated with parking restrictions and enforcement. Dr. Pruss developed a vehicle residence identification methodology during this research, that was later adopted for the annual official King County Point-in-Time counts of "unsheltered" people. Pruss presented on the state of vehicle residency to Seattle City Council in 2012, and in 2015 joined All Home - the (US HUD mandated) Seattle/King County Continuum of Care coordinating agency - where he served on the Executive Board, Governing Board and as co-Chair of the Policy Committee. Graham has worked as a Liaison for the Unhoused Community with the City of Seattle, served on the Mayor of Seattle's Innovation Advisory Council, and led the documentation of regional vehicle residency for the annual point-in-time count of unsheltered people from 2017 to 2020.
