Epidemiology PhD Program

Offered On Campus in Tucson

The UA Zuckerman College of Public Health offers the following doctoral degrees with a focus in epidemiology: Doctorate (PhD) in Epidemiology, and a PhD Minor in Epidemiology.

The PhD in Epidemiology is offered by the Department of Epidemiology and Biostatistics. Epidemiology is the scientific discipline concerned with the causes and prevention of human disease. Epidemiology focuses on the occurrence of disease among human populations, considering changes within populations over time and differences among and between populations in disease risk.

Epidemiologists today are involved in attempts to understand the causes and means of controlling AIDS and other infectious diseases, as well as chronic diseases including cancer and coronary heart disease. Much of our understanding of the links between sexual practices and AIDS risk, of smoking and cancer, of serum cholesterol and coronary heart disease, of obesity and mortality risk and of air pollution and chronic lung disease derives from epidemiologic studies.

The PhD in Epidemiology trains individuals for careers in research and teaching in academic settings, research institutes, government agencies and industry. It has been designed for students whose careers will focus on conducting investigator-initiated and collaborative epidemiologic research. On average, the doctoral program requires approximately four to five years for completion.

The first two years of this time are usually devoted to coursework, the qualifying exam, the comprehensive doctoral examinations, and development of doctoral research. The program is research oriented and centers on a major research project.

At least 46 credits are required for the major (including up to 10 units of independent study), plus a minimum of 18 dissertation units (EPID 920), and at least 9 units minimum for the minor (depending on minor department requirements). Consult the course listings for further details on specific course requirements and schedules.

The overall course of study will be developed by the student and the advisor and approved by the student's Graduate Committee and Chair of the Epidemiology Section.
