Behavioral Nutrition PhD

Doctor of Philosophy in Behavioral Nutrition


Doctoral Seminar

The high prevalence of chronic disease and obesity worldwide, and increasingly of diabetes, has added urgency to the need for qualified researchers trained in understanding the complex interaction of biology, environment, and personal behavior, as well as skilled in the development of interventions to potentially attenuate the high rates of these conditions. At the same time, there is increasing recognition of the high impact of behavior and food policy on the sustainability of the food systems on which humans depend for their sustenance.

The Ph.D. prepares graduates to conduct research, evaluation and intervention studies in Behavioral Nutrition, an emerging field dedicated to understanding the interaction between the biology and personal behaviors of individuals and their environments that contribute to health and disease and to the sustainability of food systems, and to designing and implementing interventions based on these understandings. The program draws on the strong research agendas of faculty at the College in health behavior studies and health education, psychology, behavioral nutrition, nutrition education, nutritional epidemiology, nutritional ecology, and exercise physiology as well as of faculty in other units of Columbia University, such as the Mailman School of Public Health and the School of Medicine.

In particular, the degree program prepares graduates to conduct research on the critical issues related to:

  • Determinants of health behaviors related to nutrition and to physical activity
  • Relationships among food and nutrition-related behaviors, health outcomes, and the environment
  • Design and implementation of theory-based behavioral nutrition and physical activity interventions
  • Methodological considerations in the design and evaluation of interventions.

There are three specializations:

  • Behavioral Nutrition
  • Nutritional Epidemiology
  • Nutrition and Physical Activity

Graduates holding this degree are leaders who assume research, evaluation, and intervention roles in universities and colleges as well as other settings on a variety of issues related to behavioral aspects of nutrition and environmental factors affecting these behaviors. The program prepares researchers with strong quantitative and qualitative evaluation skills as well as basic and applied behavioral skills within an educational context.

Research Training and Apprenticeship

The primary modality for training for Ph.D. students is working with their sponsor in some ongoing research project: Students will work closely with one faculty member on an ongoing research project to gain practical experience in the development of study instruments, intervention protocols, data collection, data management and analysis, manuscript preparation and submission, and presentation of results at relevant scientific meetings. During their first year after completing basic core courses, students will also participate in two semester-long part-time internships with other Columbia research labs or other organizations to gain additional research perspectives.

How to Apply

The Nutrition faculty reviews applications throughout the year. However, preference in scholarship awards will go to students whose applications arrive during the initial months of each calendar year.

To be considered for admission to the Program in Nutrition, applicants must submit the following through the Admissions application:

  • Application document
  • Official undergraduate transcript
  • Official transcripts that confirm completion of at least five of the seven master's prerequisite courses. If admitted to the Program in Nutrition, the outstanding master's prerequisites must be successfully completed prior to beginning master's courses. Please note that the following master's prerequisites must be completed within five years of beginning master's courses: introductory nutrition, biochemistry, anatomy & physiology I with lab, and anatomy & physiology II with lab. (Basic statistics, general chemistry with lab, and organic chemistry with lab can be older than five years.)
  • Two or three letters of recommendation
  • Personal essay
  • Resume
  • Graduate Record Exam (GRE) scores on the general exam.

Each application is reviewed within a few weeks of the Nutrition faculty receiving the application from the Office of Admission. Prospective students will receive formal letters informing them of their admission status.

Since applications remain "active" for one year within the Office of Admission, applications can be submitted in piecemeal. However, an application will not be forwarded to the Nutrition faculty for review until the application is submitted as complete. If you have questions about your submitted application, please contact Admissions at 212-678-3710.

Course Requirements

Doctor of Philosophy (Ph.D.)

The increasing prevalence of chronic disease and obesity worldwide has added urgency to the need for qualified researchers trained in understanding the complex interaction of biology, environment, and personal behavior, as well as skilled in the development of interventions to potentially attenuate the rapidly rising rates of obesity and chronic diseases, such as diabetes in both adults and children. 

The program prepares scholars to conduct research on the critical issues related to:

  • determinants of health behaviors related to nutrition and to physical activity;
  • relationships among food- and nutrition-related behaviors and health outcomes using techniques of behavioral epidemiology;
  • design and implementation of theory-based behavioral nutrition and physical activity interventions
  • methodological considerations in the design and evaluation of interventions.

There are three specializations:

  1. Behavioral Nutrition
  2. Nutritional Epidemiology
  3. Nutrition and Physical Activity

The graduates from this program will be leaders who will assume professorial and research roles in universities and colleges within departments of nutrition epidemiology, foods and nutrition, and physical activity, as well as assume research roles in centers for research on behavioral aspects of obesity, chronic disease prevention, and health promotion. Thus, the program aims to prepare researchers with basic and applied behavioral skills within an educational context.

Admission Requirements

Admission to the Ph.D. program involves completing the application form available online and submitting all regular admission materials, such as transcripts from all institutions attended, three letters of recommendations, and writing sample, which can be a thesis, substantial paper, or published article.

The student should have a master’s degree in nutrition or a closely related discipline from an accredited institution, along with the necessary prerequisite undergraduate courses in general, organic and biochemistry, nutrition and statistics, and human physiology. Admissions will be based on grades, GRE scores, letters of recommendation, personal statement, and an appropriate match between the applicant’s interests, the research work of the Ph.D. faculty, and funding availability.  The student will generally be expected to be full-time and to work on ongoing research projects of the faculty.

Program of Study

The general requirements for the Doctor of Philosophy include a minimum of 75 graduate credits, of which at least 45 must be taken under Teachers College registration.

For the Ph.D., the total classroom course requirement is 45-51 credits, including prior master’s degree work and 24-30 credits (advanced topical seminars, research seminar and dissertation advisement) devoted to research-related courses and activities. Students will also be expected to pass a certification examination and an advanced seminar and to write a dissertation.

Students will be expected to take courses in the following categories:

  1. Core courses: 33 points
  2. Courses to develop depth within each specialization: 15-21 points
  3. Research preparation: 21-27 points

The specific courses selected will depend on the student’s particular background, interests and goals. In consultation with a faculty advisor, students should develop a program plan early in their course of study to provide a rational basis for their course selection.

Research Training and Apprenticeship

The primary modality for training for Ph.D. students is working with their sponsor on some ongoing research project. Students will work closely with one faculty member on an ongoing research project to gain practical experience in the development of study instruments, intervention protocols, data collection, data management and analysis, manuscript preparation and submission, and presentation of results at relevant scientific meetings. During their first year after completing basic core coursework, students will also participate in two semester-long part-time internships with other Columbia research labs to gain additional research perspectives.
