The mission of the department is to improve human health through enhanced nutrition. It strives to accomplish this goal through research aimed at an increased understanding of how diet influences health, the dissemination of new knowledge about nutrition to health professionals and the public, the development of nutritional strategies, and the education of researchers and practitioners.

The department provides training and research opportunities in basic science relating to nutrition and in epidemiologic aspects of nutrition as they affect public health. Nutrition policy and the evaluation of nutritional interventions are long-standing interests of the department, particularly as they concern the populations of Latin America, Africa, Asia, and the United States. Department research ranges from molecular biology to human studies of cancer and heart disease, including the conduct of population-based intervention trials. Students learn and use the latest techniques in biochemistry, physiology, biostatistics, epidemiology, and related fields. All research, whether basic or applied, is relevant to human health.

Current research covers a wide range of topics, including large prospective studies of dietary factors in relation to heart disease, cancer, diabetes, and ophthalmologic disease; development of methods to assess nutritional status by analysis of body tissue; the interaction of nutritional factors with genetic determinants of disease; the interaction of nutritional factors and infectious agents; nutritional influence on blood pressure; effects of nutrition programs on the mental and physical consequences of malnutrition; nutritional determinants of blood lipid factors; lipoprotein metabolism; molecular mechanisms of diabetes and obesity; regulation of the intra- and inter-cellular delivery of macromolecular nutrients; and the molecular mechanism leading to atherosclerosis and thrombosis.

Degree Programs in Nutrition
The department offers the SD in nutrition, and the PhD in nutritional biochemistry/cardiovascular biology. No master’s degree programs are available.

Program Prerequisites and Requirements
All departmental degree requirements are in addition to the schoolwide degree requirements.


PhD in Biological Sciences in Public Health (Nutritional Biochemistry/ Cardiovascular Biology)

The department’s PhD program is run through the HSPH Division of Biological Sciences, an umbrella organization comprising several of the school’s departments. Prospective students should apply to the PhD program in the Division of Biological Sciences. Application is through the Harvard Graduate School of Arts and Sciences.

The PhD program in nutritional biochemistry offers rigorous training in biochemistry, cell biology, and metabolism, allowing students to work toward solving nutritional and metabolic problems in the laboratory. Students in cardiovascular biology learn to use cutting-edge technologies from molecular biology, biochemistry, and genetics to critically dissect the mechanisms underlying cardiovascular diseases, such as heart attacks, strokes, heart failure, atherosclerosis, and congenital heart disease.
