The department's research themes include environmental and occupational health, health inequality and social determinants of health, health communication, obesity and chronic disease, nutrition and infection, health policy and health care delivery, and global health. Much of the research is translational, from bench to bedside and more often bench to community and to policy. The research groups have extensive collaborations across Tufts, Boston, the U.S. and globally. There are also collaborations with community-based organizations, state and local health departments and with industry.
