David Wittenburg is an expert in interventions to promote employment for people with disabilities, particularly interventions that serve youth as they transition into adulthood. He has two decades of experience in evaluation design and program evaluation for several federal agencies.
Wittenburg leads business development activities related to disability projects. He recently worked in senior leadership roles on three Social Security Administration demonstration projects, helping to design and implement experimental and nonexperimental approaches to assess the efficacy of return-to-work interventions for people with disabilities.
Wittenburg, who joined Mathematica in 2005, presents his findings to diverse research and policy audiences, including in congressional testimony, conference presentations, reports, and journal publications. He edited two special journal volumes on employment topics related to people with disabilities for the IZA Journal of Labor Policy and the Journal of Disability Policy Studies. A member of the National Academy of Social Insurance and formerly a senior associate at the Urban Institute and the Lewin Group, he holds a Ph.D. in economics from Syracuse University.
