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.
- Program evaluation
- Use of administrative and survey data for research on working-age people with disabilities
- Employment and Training
- Medicaid and CHIP
- Human Services
Purvi Sevak’s primary research interest is in policies to support the employment and well-being of people with disabilities and chronic conditions. Her work spans the fields of health, employment, and program evaluation.
Through Mathematica’s Center for Studying Disability Policy, Sevak has partnered with state vocational rehabilitation (VR) agencies, centers for independent living, and other community based organizations working to help people with disabilities achieve their employment and independent living goals. She has worked with state VR agencies to help them leverage data and technology to improve service delivery and outcomes for youth with disabilities as they transition to adulthood. This includes the development and support for the Vocational Rehabilitation Program Evaluation Coach, a free web-based tool that assists VR agencies with evaluation to inform program improvement. Sevak has co-edited two special volumes of the Journal of Vocational Rehabilitation.
Sevak has extensive research and program evaluation experience. She is currently leading the impact evaluation of a work-based learning demonstration for transition aged youth in Vermont. She has designed or led the quantitative evaluation of several notable federally-funded interventions including two Health Care Innovation Awards for CMS and the Substantial Gainful Activity Demonstration for the Rehabilitation Services Administration. Her published research has included studies examining SSI program participation, geographic variation in employment and program use, barriers and facilitators to employment, retirement and savings behavior, the ability of intensive care management to improve outcomes for Medicare beneficiaries with complex health needs.
Sevak holds a Ph.D. in economics from the University of Michigan. She has been at Mathematica since 2013 and was previously a professor in the Economics department at Hunter College, in the City University of New York.

High-Intensity Care Management Program Shows Promise for Reducing Hospital Use and Spending for Super Utilizers
Recently published findings from an evaluation conducted by researchers at Mathematica found that a high-intensity care management program modeled on the Camden model led to substantial reductions in short-term service use and spending for a small group of super utilizers in four states.
