Mathematica is one of two policy research centers that lead the SSA's Disability Research Consortium. The DRC fosters new research from a team of disability policy experts from Mathematica and three universities.
Disability policy analysis and program evaluation
Qualitative and quantitative research
Housing for people with disabilities
- Employment and Income Support
- Human Services
Denise Hoffman’s research focuses on the employment, program participation, health insurance, and housing of adults with disabilities. Her current research includes an analysis of the Benefit Offset National Demonstration, which tests the effects of an alternative benefit schedule on Social Security Disability Insurance (DI) beneficiaries’ employment and DI benefit receipt. In addition, she is conducting several analyses as part of the Social Security Administration Disability Research Consortium, including an analysis of work-related overpayments to DI beneficiaries and, separately, an assessment of the extent to which Medicare and private insurance meet the employment-related health care needs of people with disabilities.
Hoffman’s past research includes impact analyses of federally-funded initiatives intended to help people with disabilities become self-sufficient, including Ticket to Work, the Demonstration to Maintain Independence and Employment, and the Non-Elderly Disabled Housing Voucher Program. She also used the American Housing Survey to conduct quantitative analyses comparing the housing and neighborhood characteristics of people with and without disabilities.
Hoffman, who joined Mathematica in 2010, serves on the AcademyHealth Disability Research Interest Group Committee. She holds a Ph.D. in economics from the University of North Carolina at Chapel Hill.
