Gina Livermore (PhD, Economics, University of Wisconsin-Madison) is a senior fellow at Mathematica and director of Mathematica’s Center for Studying Disability Policy. Her work focuses on improving the economic well-being of transition-age youth and working-age people with disabilities and includes numerous studies on the employment of Social Security disability beneficiaries. For more than 25 years, she has evaluated a wide range of interventions and policies affecting the employment of people with disabilities, including evaluations of the Social Security Administration (SSA) Ticket to Work program, interventions implemented by state vocational rehabilitation agencies and American Job Centers, and a customized employment model for individuals with intellectual disability and autism. Her work also includes studies of Social Security Disability Insurance beneficiaries’ access to health care during the Medicare waiting period, health insurance coverage of workers with disabilities, the characteristics and employment of disability beneficiaries with mental health conditions and intellectual disability, the consequences of disability onset among older workers, and studies of long-term poverty and material hardship among adults with disabilities. Dr. Livermore co-directed the Mathematica center that is part of SSA’s Disability Research Consortium and is the project director for the SSA evaluation of the Promoting Readiness of Minors in Supplemental Security Income (PROMISE) demonstration. Before joining Mathematica in 2007, Dr. Livermore served as assistant director of the Cornell University Institute for Policy Research and was a vice president at The Lewin Group. Dr. Livermore co-authored the chapter “Youth Transition” and presented it with David Wittenburg at Lessons from SSA Demonstrations: A State of the Science Meeting.
