Von Nebbit's practice and research experiences are in the areas of urban African American children and youth, with a primary research agenda of increasing empirical and theoretical knowledge of the effects of living in urban public housing on minority adolescents’ health and well-being. His research assesses how exposure to community and household violence, peer networks, and social cohesion and belonging are related to the mental, behavioral and physical health of adolescents.
In addition, Nebbitt authored the book "Adolescents in Public Housing: Addressing Psychological and Behavioral Health," a first volume to use data collected from youth in public housing living multiple U.S. cities. His research has garnered support from the National Institute of Drug Abuse, National Institute on Minority Health and Health Disparities, the Silberman Foundation and the MacArthur Foundation.
Prior to this position, Nebbitt was an associate professor at the Jane Addams College of Social Work at the University of Illinois at Chicago. He also served as director of the Cochran Community Center of the St. Louis Housing Authority.
