• Dr. Culhane studies homelessness and housing policy. His research has been instrumental in a national shift in how society addresses homelessness, including expansions of supported housing for people who are chronically homeless, and housing stabilization programs for families and individuals at-risk of homelessness. • Dr. Culhane co-directs the Cartographic Modeling Laboratory (CML), which applies spatial data and spatial analysis tools to the study of how the social and built environments influence health and behavior, particularly in an urban context.
