During his tenure, Thomas led the development of New York’s GIVE (Gun-Involved Violence Elimination) Initiative, which employs evidence-informed, data-driven approaches to reduce violence. He also established the Research Roundtable on Criminal Justice, a statewide criminal justice community connecting research with policy.

Before his work in New York, Thomas served as Chief of Staff to the Office of Justice Programs at the US Department of Justice, where he worked with the nation’s principal criminal justice grant-making and research agencies to integrate evidence, policy, and practice. He played a lead role in establishing the National Forum on Youth Violence Prevention, a network of federal agencies and local communities working together to reduce youth and gang violence. Thomas was also founding member of the Neighborhood Revitalization Initiative, a place-based development effort that was recognized by HKS as one of the Top 25 Innovations in Government for 2013.
