The Tufts University Friedman School of Nutrition Science and Policy offers both Master's and Doctor of Philosophy degrees in Nutritional Epidemiology. The program is designed to train students in the design, implementation, and analysis of epidemiologic studies that address questions of dietary intake and nutritional status. Affiliated faculty, selected for their leadership in the fields of both nutrition and epidemiology, impart the highest standard of excellence in education through both teaching and research experiences. The interactive relationship with other programs within the school; with the Tufts University School of Medicine, the Tufts Medical Center, and the Jean Mayer USDA Human Nutrition Research Center on Aging, provides a rich environment for collaborative and cross-discipline instruction. Our affiliation with several longitudinal studies, including the Framingham Heart Study, the Normative Aging Study, the Jackson Heart Study, and the Baltimore Longitudinal Study on Aging, provides opportunities for direct research experience. Students who complete the Nutritional Epidemiology program will graduate with the necessary analytical, technical, and communication skills required for preeminent research and teaching positions in academics and government.

Why study Nutritional Epidemiology?

The effects of dietary intake and nutritional status on health are complex. Multiple nutrients work together in the body, with differing impacts on different systems and under differing environmental conditions. The effects of dietary intake may be modified or confounded by other exposures, including physical activity, smoking, and alcohol consumption. Understanding and untangling specific effects requires an understanding of the complex interactions among exposures and the technical skills for clarifying them in population-based data. This requires training in nutritional biochemistry, biostatistics, and epidemiology. Although controlled human studies are important to the clarification of specific biologic actions, relationships between behaviors and exposures and health outcome need to be tested in free-living settings, where other factors are not controlled. Results may also vary in different groups and environments. Epidemiologic studies may generate important new ideas about health risks or protective factors, and offer suggestions for public health policy.

What You Will Learn

The curriculum combines traditional academic course work with practical training, so that students acquire an in-depth knowledge in general nutrition, nutritional biochemistry and physiology, biostatistics, and epidemiology. They develop an understanding of how to design and conduct epidemiologic research studies, and gain hands-on experience in essential techniques in data analysis and presentation. Students take most of their academic courses at the Friedman School of Nutrition Science and Policy and at the School of Medicine. Additional courses in advanced epidemiology are available by cross-registration at Boston University.


The Nutritional Epidemiology Program leads to the Master of Science and Doctor of Philosophy degrees. A full listing of course descriptions is available in the general catalog of the Friedman School of Nutrition Science and Policy

Master of Science

The curriculum includes core courses in the areas of nutrition, biochemistry, biostatistics, and epidemiology. Each student completes a specialization (3-5 courses). A minimum of 16 credits is required for the M.S. degree. Unless otherwise noted, each course is equivalent to one credit. The exact number of required courses will depend upon the student's prior academic preparation.

Doctor of Philosophy

Students enrolled in the doctoral program must have completed courses equivalent to the Nutritional Epidemiology master's degree based on previous graduate-level coursework taken either at the Friedman School or elsewhere. Students entering at the Ph.D. level must complete or be exempted from all required courses of the M.S. curriculum. Students in the doctoral program must first pass a written and oral qualifying examination, and then complete and formally defend a doctoral dissertation based on original research.

Combined Degree Programs: MS/MPH

A combined degree program, in association with Tufts University's School of Medicine, leads to the Master of Science and the Master of Public Health. Learn more about this combined degree program.


Students come from a variety of backgrounds: from biostatistics, epidemiology, nutrition, or biology.


Undergraduate level courses in general nutrition, general biology, general chemistry (with lab), organic chemistry and biochemistry.

Please be advised that students taking General Nutrition courses to fulfill program prerequisites must have those courses approved by the Friedman School in advance.


The nutrition core provides students with an understanding of basic and applied nutrition, biostatistics, and nutrition science policy. Courses in these areas reflect the broad science and policy mission of the school. Students entering with an appropriate master's degree may submit requests to waive individual courses or to take exemption exams.

Nutritional Epidemiology graduates are prepared to work in agencies and organizations such as:

  • University Departments of Epidemiology or Nutrition
  • Government Agencies such as:
    • Centers for Disease Control and Prevention
    • National Center for Health Statistics
    • U.S. Department of Agriculture

Jean Mayer USDA Human Nutrition Research Center on Aging

Scientists at the HNRCA examine how nutrition impacts healthy aging and the role nutrition plays in preventing diseases of the aging. The HNRCA, which is an independent research facility  located two blocks away from the Friedman school on the Tufts Boston campus, was established in 1977 as a unique partnership between the USDA and the University.  Many of the scientists at the HNRCA’s 20 research labs are also Friedman School faculty.  Friedman students have unique opportunities to conduct research  under the supervision of HNRCA scientists who have international stature in their respective areas of research expertise.
