Hamilton has designed, implemented, and directed numerous large-scale evaluations and demonstrations of programs intended to improve the well-being of low-income populations. She currently is leading a random assignment evaluation of SaveUSA, a new tax-time savings program for low-income individuals, and is coleading an implementation evaluation of Project Rise, a new education-conditioned internship program for “disconnected” young adults. She recently served as project director of the Employment Retention and Advancement (ERA) evaluation, a study that mounted — in 18 sites — random assignment tests of innovative strategies to help low-income workers maintain and advance in their jobs. She also led implementation research efforts for a related project — the United Kingdom’s ERA project, which was the first large-scale randomized social policy experiment undertaken in the U.K. Previously, she directed the National Evaluation of Welfare-to-Work Strategies, a random assignment study of more than 55,000 adults and 11,000 children in seven sites. Since joining MDRC in 1983, Hamilton has authored many reports and syntheses, presented research results at numerous conferences, and given briefings for program operators, government officials, policy analysts, and members of the press.
