Jason Markesich

Senior Director, Health Policy Assessment Division

Jason Markesich manages a growing team of survey researchers and statisticians in the Health Unit’s Policy Assessment Division and helps establish and implement the strategic vision of that division. He leads various initiatives to improve operational efficiencies and data quality. Before joining the Health Unit, Markesich served as the director of survey operations from 2007–2015. In this role, he oversaw telephone and field-related data collection activities performed out of Mathematica’s Survey Operation Centers (SOCs), set up satellite data collection facilities and managed vendor partnerships, and implemented the SOCs’ state-of-the-art contact center management system.

In addition to his management responsibilities, Markesich specializes in the design and direction of large-scale multimode and longitudinal surveys and evaluations. He has particular expertise in studies that survey vulnerable and hard-to-reach populations (such as low-income families and people with disabilities) and qualitative research methods. Currently, Markesich is the project director on the National Beneficiary Survey. This study, sponsored by the Social Security Administration’s Office of Retirement and Disability Policy, collects data on the employment-related activities of working-age Social Security Disability Insurance and Supplemental Security Income beneficiaries. He has held leadership roles on studies funded by the U.S. Department of Health and Human Services, the Centers for Medicare & Medicaid Services, and the Assistant Secretary for Planning and Evaluation.

Markesich, who joined Mathematica in 1999, presents his work widely at professional conferences, such as the American Association for Public Opinion Research annual conferences, the Federal Computer-Assisted Survey Information Collection workshops sponsored by the Bureau of Labor Statistics and the Census Bureau, the International Conference on Methods for Surveying and Enumerating Hard-to-Reach Populations, and the Interagency Subcommittee on Disability Statistics conference. He has published in Survey Practice and is the author of several publications on how to make surveys more accessible for people with disabilities, including a chapter in Counting Working-Age People with Disabilities: What Current Data Tell Us and Options for Improvement. He holds an M.S. in public policy from Rutgers University.
