Associate Professor, Public Administration and International Affairs


Sarah Hamersma is an Associate Professor of Public Administration and International Affairs and a Senior Research Associate in the Center for Policy Research. She taught at the University of Florida before coming to Syracuse University. Much of her most recent research focuses on health and nutrition programs, examining their consequences for food insecurity, health outcomes, and labor supply. New work funded by the Cornell Population Center and Center for Aging Policy Studies (Syracuse) will investigate food assistance and labor market decisions over the life cycle in New York State. An additional new project, funded by the USDA through the University of Kentucky Center for Poverty Research, will use the Panel Study of Income Dynamics to study the intergenerational transmission of food insecurity and the role of higher education and food assistance in breaking such transmission. Sarah received her Ph.D. in economics from the University of Wisconsin-Madison in 2004
