Nutrition Data Science

The effects of dietary intake and nutritional status on health are complex. Understanding and untangling specific effects of overall diet and individual nutrients requires an understanding of the complex interactions among dietary, lifestyle, metabolic and genetic exposures and the critical-thinking skills for clarifying them in population-based data.

The Nutrition Data Science program is designed to train students in the design, implementation, and analysis of epidemiologic studies that address questions of the role of dietary intake and nutritional status in disease prevention.

The Nutrition Data Science Program 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. Students 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.

This program is in the Division of Nutrition Data Science.

Students take most of their academic courses at the Friedman School of Nutrition Science and Policy although additional courses in advanced epidemiology and statistics are available by cross-registration at Boston University and at the Harvard School of Public Health.


Life Sciences 

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.

Nutrition Science

Undergraduate level courses in General Chemistry and General Biology.

The curriculum includes core courses in the areas of nutrition, biochemistry, biostatistics, and epidemiology. A minimum of 48 semester hour units is required for the M.S. degree. Unless otherwise noted, each course is equivalent to three semester hour units. 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.

Current students should refer to the degree requirement worksheet associated with their year of entry for the most accurate course requirements.

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.

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, and the Baltimore Longitudinal Study on Aging, provides opportunities for direct research experience.

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.
