About Purvi

Purvi Sevak's expertise includes quantitative research and using large survey databases to conduct public policy research related to health and disability program participation and employment.


Sevak is currently leading the Survey of Disability and Employment, funded by the National Institute on Disability and Rehabilitation Research (NIDRR) in the U.S. Department of Education. The survey, fielded to 3,000 recent vocational rehabilitation applicants, is designed to identify barriers and facilitators to employment for people with disabilities. Also for NIDRR, she is leading several research projects examining the role of individual and environmental characteristics in explaining disparities in employment outcomes among people with disabilities. In addition, Sevak is leading an impact analysis of two Health Care Innovation Awards-Primary Care Redesign awardees to assess improvements in the coordination, efficiency, and quality of patient care.


Sevak came to Mathematica in 2013 from Hunter College, where she was a professor in the economics department for more than a decade. Much of her research has been on retirement-related issues, such as labor supply decisions, savings behavior, and long-term care, or on issues related to disability. Her work includes studies of the impacts of recession on Supplemental Security Income participation and on workers with chronic health conditions, and the effects of Medicaid policies on private savings. Sevak holds a Ph.D. in economics from the University of Michigan. She is a member of the Association for Public Policy Analysis and Management and the American Economic Association.
