The Department of Global Health and Social Medicine applies social science and humanities research to constantly improve the practice of medicine, the delivery of treatment, and the development of health care policies locally and worldwide. Major efforts include developing the science of global health delivery implementation; advancing equity in health care delivery; and educating students and researchers on biosocial determinants of disease, health care delivery, and responsible practice of medicine. The Department is the central structure to help organize global health activities, especially medical education experiences, at Harvard Medical School.
