Xavier de Souza Briggs’s creative application of social science to pressing social problems has made him a trusted adviser to policymakers and philanthropists alike. His research on housing opportunity, spatial segregation, social capital, and the “geography of opportunity” have influenced housing and urban-planning policies at both local and federal levels. While working in the U.S. Department of Housing and Urban Development and the White House Office of Management and Budget, Briggs expanded funding for social science research on policy effectiveness and led key developments in public and low-income housing. More recently, he has studied job quality and equitable climate action.
