Programs and Disciplines


The PhD Program in Biological Sciences in Public Health (BPH), established in 1993, trains students in individual fields of biological research with a focus on understanding, preventing and treating diseases affecting large populations. Students in the BPH program obtain a broad interdisciplinary knowledge of both mechanistic and quantitative approaches to biomedical research.

Major Areas of Investigation include:

  • The Metabolic Basis of Health and Disease
  • Immunology and Infectious Diseases
  • Gene-Environment Interactions
  • Inflammation and Stress Responses

All of these areas are studied with an emphasis on biochemical, cell biological and genetic approaches to delineating disease mechanisms.  Our research, whether basic or translational, is relevant to human health. Students apply cutting-edge technologies to the solution of worldwide problems with a focus toward better treatment and prevention of human diseases. Our program embraces the idea that progress in a given disease area is optimally promoted by a close interaction between scientists from diverse disciplines, including genetics, cell biology, biochemistry, physiology, and systems biology.  Core quantitative disciplines like biostatistics and epidemiology are also fundamental to analyzing large datasets, such as those generated from “omics” approaches, and for assessing the broad impact of health problems, allowing us to look beyond individuals to entire populations.  With our roots in biology, we are able to confront the most pressing diseases of our time, gaining insights into their underlying mechanisms and uncovering novel therapeutic opportunities.

Current research within BPH laboratories includes, but is not restricted to, the following diseases or disease risk factors:

  • AIDS

The BPH program is rooted in the rich and diverse environment of the Harvard School of Public Health, dedicated to advancing the public’s health through learning, discovery, and communication. The field of public health is inherently multi-disciplinary and so, too, are the interests and expertise of the School’s faculty and students, which extend across the biological, quantitative, and social sciences. From advancing scientific research to training national and international leaders, the Harvard School of Public Health has been at the forefront of efforts to benefit the health of populations worldwide. Shaping new ideas in our field and communicating them effectively will continue to be priorities of the BPH Program in the years ahead as we serve society’s changing health needs.  Disciplines include the following scientific areas:


The complex interplay of biological processes with environmental factors as they apply to chronic, multigenic, and multifactorial diseases is the focus of the Department of Genetics and Complex Diseases. Department faculty aim to elucidate the molecular mechanisms underlying the intricate interaction between genetic determinants and their divergent responses to environmental signals to affect the health of human populations. Research focuses on several broad categories, including metabolism, stress response and inflammatory signaling. Areas of study include diseases such as diabetes and cancer, disease-risk conditions such as obesity, age-related (chronic) diseases, and the normal aging process. These are investigated both at the mechanistic level and in the context of population studies.


The Department of Immunology and Infectious Diseases focuses on the biological, immunological, epidemiological, and ecological aspects of viral, bacterial, protozoan, and helminthic diseases of animals and humans and the vectors that transmit some of these infectious agents. Research emphasizes basic pathogenic mechanisms that may lead to better diagnostic tools, the development of vaccines and other immune interventions for prevention and control of infection and disease, and the identification of new targets for antiviral and antiparasite drugs. Laboratory-based research may be supplemented by field-based studies of epidemiological and ecological aspects of infectious disease transmission and control. Diseases of developing countries are emphasized, including HIV, tuberculosis, malaria and other parasitic diseases. Immunologic studies focus on genetic regulation of the immune response; molecular mechanisms of the regulation of class II genes; the function and regulation of T-cell-derived cytokines; and cytokines involved in the regulation of inflammation.


The concentration focuses on normal and pathological functions of organisms. It centers on the respiratory system because the system presents an immense, thin surface area to the environment, and thus is an important route of entry to the body as well as a site of damage from toxins and infections. Areas of study include molecular and cellular mediators and adhesion molecules involved in pulmonary inflammation; toxic mechanisms of inhaled air pollution particles; biomechanics of cells and tissues in normal and diseases lungs; smooth muscle and airway constriction in asthma; and environmental agents and risk of lung infection.


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 an 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 and regulation of the intra- and inter-cellular delivery of macromolecular nutrients; determinants of blood lipid factors, lipoprotein metabolism; molecular mechanisms of diabetes and obesity; regulation of the intra-and-intercellular delivery of macromolecular nutrients; and the molecular mechanisms leading to atherosclerosis and thrombosis.

Research Facilities

Located in the Longwood Medical Area of Boston, the program brings together faculty in the biological sciences throughout Harvard University. The Medical Area, which includes the Harvard T.H. Chan School of Public Health, Harvard Medical School, Harvard Dental School, and a cluster of hospitals, comprises one of the most concentrated areas of scientific research facilities in the United States. The interaction Program in Biological Sciences in Public Health (BPH) at Harvard T.H. Chan School of Public Health of faculty working at associated institutions, through joint teaching and research, enables the program to serve as a meeting place for the biological, medical, physical, and chemical scientists. This provides students and faculty alike with a wider range of experience and techniques than may be found in any single discipline or department.

At the Harvard T.H. Chan School of Public Health alone, modern research laboratories are housed on 18 floors of three buildings. Students have access to the Countway Library, one of the most complete biomedical research collections in the nation.

The main Harvard University campus in Cambridge encompasses a wide variety of strong academic departments and facilities in the humanities and sciences. The program specifically interacts with the biological sciences programs in molecular and cellular biology, organismic and evolutionary biology, and biophysics.

Program of Study

The program offers opportunities in a wide range of laboratory experiences and considerable interaction among the program components. Academic programs fulfill needs and goals through core and advanced courses, seminars, rotations in laboratories, and a qualifying examination. Rotations are an integral part of the program; they allow students to investigate several types of research and laboratories before choosing a dissertation laboratory. Students choose a dissertation laboratory by the end of the first year.

Although individual programs vary, generally students take a qualifying examination during their second year. After successful completion of the qualifying examination, the dissertation advisor supervises the doctoral candidate’s research and study, with an advisory committee periodically reviewing progress.

Typically, about four years of laboratory work are needed to complete the dissertation research, which is defended before three examiners. Generally, students complete the degree in five to six years.

The Informal Curriculum

Outside of the classroom, the program sponsors a variety of activities that bring together students and faculty with a broad range of research interests. Important elements of this "informal curriculum" are seminars, journal clubs, and retreats. These sessions give students the chance to interact with faculty and postdoctoral fellows from laboratories throughout the Medical Area, and to learn about research in diverse fields. Student-run journal clubs and seminars provide opportunities to learn how to give talks, critically evaluate scientific literature, present data, and take part in group discussions. City-wide seminars draw researchers from all area institutions into a larger scientific community. Some students serve for at least one term as teaching assistants for graduate and medical school classes, or for undergraduate courses taught in Cambridge. Student organizations plan various social and academic activities.

Combined Degree Programs

The program, in conjunction with Harvard Medical School, offers a combined MD/PhD program to train physician-scientists to work at the forefront of biomedical research and to provide an interface between the most basic and technical research and its clinical application at the bedside. The program seeks to provide students with the most thorough and up-to-date medical education and training for research careers. Students who are interested in working toward simultaneous MD and PhD degrees should complete the application for admission to Harvard Medical School and the MD/PhD Program.


Applicants wishing to do research in areas of metabolic dysregulation in complex disease (obesity, metabolic syndrome, cancer), health effects of environmental exposures (air pollution, lung infection, asthma), nutritional biochemistry (nutrient transport and metabolism), gene-environment interactions (epigenetics, inflammation, stress response), immunology and infectious diseases (host-pathogen interactions and protozoa, helminths, viruses or bacteria) usually apply to the Biological Sciences in Public Health (BPH) program.
