The program is a cohort-based program emphasizing small-group learning and collaboration. The program is designed for three years – two years at Harvard, plus one year in a field-based doctoral project – although some students may take up to four years to complete the program. Academic training in the DrPH covers the biological, social, and economic foundations of public health, as well as essential statistical, quantitative, and methodological skills in the first year, an individualized course of study in your second year, and a field-based, capstone project called the DELTA (Doctoral Engagement in Leadership and Translation for Action) in the final year(s) of the program. PhD programs are offered under the aegis of the Harvard Graduate School of Arts and Sciences.
