The Division of Biological Sciences is an umbrella organization encompassing the HSPH Departments of Environmental Health, Genetics and Complex Diseases, Immunology and Infectious Diseases, and Nutrition. In most of these departments, two doctoral degrees are offered: the doctor of philosophy (PhD) and the doctor of science (SD).
The Division of Public Health Practice serves as a conduit between the work of HSPH academic departments, governmental and corporate agencies, and the community. The division's mission, "translating passion and learning into advances that protect the health of all," encompasses education, research, and service. Through education the division ensures that its students graduate with the core competencies of public health, including assessment, policy formulation, program development, and quality assurance, and with the vision to become effective public health leaders.
