The Leah Zallman Center for Immigrant Health Research partners with immigrant communities, advocates, policymakers, and social and health systems on actionable research to improve immigrant health and well-being.

Led by Dr. Jessica Santos, we are a group of social scientists and public health researchers who conduct rigorous mixed methods research to answer relevant questions about the health of immigrants and communities. We work in partnership with funders, advocates, health systems, and immigrant communities to develop and conduct actionable, high-impact research to advance policy that supports immigrant health and health equity.

The Leah Zallman Center is a research center at the Institute for Community Health (ICH). The Center is proud to build on ICH’s long history of using participatory methods to ensure that community voices in research are amplified to the state and national level as part of evidence-based policymaking.

In February, LZC released Iced In: The Actions and Impacts of U.S. Immigration and Customs Enforcement (ICE) in Massachusetts in 2025. We summarized the background, approach, findings, and calls to action in a poster for easy viewing.
