Over the past decades, global migration has grown to reach unprecedented proportions and this trend is expected to continue, driven by economic forces, social inequities, climate change, and environmental degradation. Massive human flows impact population health in countries of origin, transit, and resettlement. Too often, newcomers face significant barriers to health care and face poor outcomes.

The Dalla Lana School of Public Health (DLSPH) has a long tradition of interdisciplinary scholarship on issues of migration and displacement. Several faculty members are part of well-established research networks and work in partnership with community organizations, government, and international agencies.

Acknowledging the fundamental importance of this phenomenon as a global determinant of health, and in response to growing interest by students and faculty, the School is working to strengthen public health and migration as an area of research and education. Researchers and educators are focusing on both the local and the global, from multiple perspectives, and apply a variety of epistemological and methodological approaches.
