Grounded in public health policy, economics, demography, history, law, and the practical application of systems thinking, the Center promotes the convergence of the diverse disciplines required to understand and build capacity to work across sectors and levels of organization. We focus on practical approaches to reducing health inequities and provide a scholarly basis for the development of healthy urban centers and a deeper understanding of the linkages between the health of immigrant, refugee and migrant worker communities and the persistence of health disparities.
