Doctor of Philosophy in the Field of Epidemiology

Program Director S. Cleary                                                                                              

The purpose of the doctor of philosophy program is to prepare students for a career in epidemiologic research in an academic, government, or industry setting. The PhD graduate is expected to have knowledge across a wide range of epidemiologic theories and methods and specific knowledge of the epidemiology of one of the following areas: chronic disease, infectious disease, environmental and occupational health.

Doctoral students are required to pass a written comprehensive examination and to complete a dissertation. 

At the completion of the doctoral program in epidemiology students will be able to:

  • Demonstrate understanding of general and specialized epidemiologic concepts;
  • Develop a research protocol;
  • Conduct and analyze data from a research study; and
  • Disseminate research findings.

Admissions Requirements

Specific admission requirements are shown on the Graduate Program Finder and in the School of Public Health program webpage.

Applicants must hold an undergraduate degree from an accredited institution of higher learning. Although not required, most admitted students have completed a master's degree prior to admission. Before applying, applicants must provide evidence of the completion of these required prerequisites: 

  • Calculus I and II- 6 credits
  • Human Biology- 8 credits

And, the following courses are highly recommended admission prerequisites:

  • Linear Algebra- 3 credits
  • SAS- 3 credits

If desired, a student may complete the MS or MPH program prior to admission to the PhD degree program, in which case no more than 24 credits from these degrees may be applied to the PhD coursework requirements. In this instance the student will be required to take a minimum of 27 additional credits of coursework. The distribution of these courses between epidemiology and statistics will depend on the nature of the master's degree and whether the transferred credits will be used to defray epidemiology or statistics coursework. All applications are submitted through

The following requirements must be fulfilled:
