Harvard University offers a fully funded PhD program in Biological Sciences in Public Health. PhD students will gain expertise in the prevention and treatment of diseases that affect thousands—even millions—of people. Working with leading public health scientists, fellows will learn both mechanistic and quantitative approaches to biomedical research, while specializing in one of four areas of investigation: the metabolic basis of health and disease, immunology and infectious diseases, gene-environment interactions, or inflammation and stress responses. All accepted students are fully funded and receive tuition, insurance and a stipend.
