Daniel Welsh

Daniel Welsh leads complex surveys and large-scale data collection for federal agencies, foundations, and other partners seeking actionable evidence to improve human services programs and policies. His work focuses on multimode surveys and data collection strategies for engaging diverse populations.

Since joining Mathematica in 2018, Welsh has held leadership roles on projects for the Food and Nutrition Service (FNS), Social Security Administration, and major foundations including the Gates and Walton Family Foundations. He currently serves as survey director of the National Institutes of Health–funded MyGoals Long Term Study, overseeing collection of multimode surveys and biospecimen data for a study examining employment coaching and health outcomes. He is also deputy survey director of the FNS-funded Women, Infants, and Children (WIC) and Farmers’ Market Nutrition Program (FMNP) Modernization Evaluation, leading recruitment strategy and survey implementation across WIC and FMNP agencies nationwide. Previously, Welsh directed the Massachusetts Economic Conditions and Household Opportunity Survey, a multimode survey of 33,000 households that generated baseline estimates of family wealth across Massachusetts.

Before joining Mathematica, Welsh worked in legal aid organizations where he provided legal rights education and direct services to workers and families with low incomes. Those experiences continue to shape his approach to research in complex service environments. Welsh holds a BA in anthropology and Spanish from DePauw University and is a certified Project Management Professional.
