Ph.D. students admitted into the Graduate Field of Nutrition are guaranteed financial support from the Division of Nutritional Sciences (DNS) for 4.5 years (nine academic year semesters and four summers) on the condition that they maintain good academic standing, have a DNS faculty member serve as their Special Committee chair, and meet expectations in conducting their teaching and research responsibilities. The support consists of a twelve-month stipend, full academic year tuition, and coverage for the individual health insurance plan. Financial support may be in the form of teaching assistantships, graduate research assistantship, Cornell and DNS fellowships, external fellowships, traineeships, or other Cornell funding and may vary each semester. All graduate students in the Graduate Field of Nutrition are expected to serve as a teaching assistant for at least one semester.
“The university is committed to an equitable, supportive, and professional environment for graduate education. Assistantships help students develop academic rigor and creativity, independent judgment, intellectual honesty, and the ability to communicate their knowledge, while providing financial support.”
-Cornell University Graduate Student Assistantships Policy
Teaching assistants (TA) are appointed to support teaching of a course and may assist in teaching a section, leading discussions and/or laboratory sections, and preparing and grading exams, among other responsibilities. Because students funded through assistantships are expected to make progress towards their research degrees, assistantship hours for TA appointments are limited to 15 to 20 hours per week, averaging no more than 15 hours per week. Cornell is committed to helping students have a successful teaching experience and provides many exceptional teaching resources, workshops, and training programs.
When appointed on a graduate research assistantship (GRA), students focus on thesis or other degree-related research of a type that is required from all candidates for the degree. Because a student devotes considerable time to dissertation research, the time spent on research connected with the project is expected to be significant. GRAs are typically supported by grants obtained by their chair. Fellowships obtained by a student’s chair or by the student also support students in pursuing their graduate studies and research. More information regarding assistantships can be found in Cornell’s Graduate Student Assistantships policy.
Additional Funding Opportunities: Cornell University also provides additional competitive funding opportunities to support graduate students. You can explore Cornell and external fellowships for new and continuing graduate students here. The Graduate Field of Nutrition nominates incoming students for Cornell and Diversity fellowships.
Our students also successfully compete for a variety of Cornell-funded research awards, such as those from the Office of Engagement Initiatives, the Genomics Scholars Program, Atkinson Center, and the Society for the Humanities, to name a few. Students are also highly successful in receiving national and international research fellowships.
Tailor your coursework
Tailor your coursework
Training within the Graduate Field of Nutrition is individualized. YOU are able to tailor your coursework to meet your individual interests and goals. The Field of Nutrition has few coursework requirements for students in the Ph.D. Program as described below. In general, your coursework is decided based on discussions with the members of your special committee. During the first year, while you are deciding on your committee chair who serves as your primary research mentor, the Director of Graduate Studies (DGS) serves as your temporary advisor, assisting you as needed in decisions about coursework and answering any questions that you may have about the program and your course of study.
Ph.D. students in the Graduate Field of Nutrition choose two minor fields of study for their degree. Current students have selected minors in over 30 different graduate fields ranging from education to soil science to biophysics.
The most commonly chosen minors are:
- All incoming graduate students are required to take NS 7030 Seminar in Nutritional Sciences (attendance only, you do not present a seminar your first semester). Ph.D. students attend four additional semesters of NS 7030, and make three presentations (total 5 attendances and 3 presentations). Doctoral students have the option of replacing one presentation and one semester of attendance in NS 7030 with the successful completion of NS 7040, the Division of Nutritional Sciences’ grant writing course. NS 7040 also serves as an opportunity to develop a proposal, which typically contributes to important preparation for the A exam.
- Many of our graduate students elect to take macronutrients (NS6320), micronutrients (NS6310), and a biometry series (BTRY 2010 and 6020) also in their first year.
- You may sign up for dissertation research credits any semester (NS 9990 Ph.D. Thesis). The number of credits is variable.
Examination for Admission to Ph.D. Candidacy (A exam): To qualify as a Ph.D. candidate, each graduate student must pass what is called an A exam. The Graduate School requires that the A exam be completed by the end of the student’s 6th semester. Passing the A exam means the graduate faculty believes that you are ready to proceed with the degree program.
Dissertation defense (B exam): The B Exam is an oral defense of your Ph.D. dissertation. The B exam consists of a public research presentation and then an oral defense with your special committee members.
Our faculty support graduate studies
Our faculty support graduate studies
Each graduate student in the Ph.D. program is required to form a special committee. This committee is responsible for guiding your graduate work. The committee advises on coursework, reviews your progress, and generally oversees all aspects of your graduate work. The special committee includes the chair who is your research mentor and will supervise your dissertation research; two faculty members representing your two “minor” subjects or areas of study; and a field-appointed member representing the Field of Nutrition. The minor members represent the minor fields of study and provide expertise to strengthen your dissertation research and/or to provide you with training to support your career goals.
You must select your special committee chair during the first year of the program. Typically, the choice of minors and the selection of additional committee members involves discussions with your chair. The Graduate School requires that your full committee to be established by the end of the third semester of study. You may make changes to your committee after it is established; it is important to establish your committee early because the special committee guides your graduate work.
You will need to meet with the Director of Graduate Studies (DGS) when you have most of your committee members identified; in this meeting you will discuss the appointment of a Graduate Field of Nutrition faculty member to serve as your field-appointed member. This faculty member should provide a broad view of the discipline of nutrition, thus this committee member typically has interests that complement the other members of your committee (for example, if you were studying zinc supplementation in population level interventions, your field member might be a molecular nutrition faculty member studying animal models of zinc nutrition). Typically, students come up with two or three faculty members in the Field of Nutrition who are mutually acceptable to the student and the DGS, and then the DGS appoints one of them to serve in this capacity.
Selecting a mentor during your first year/rotations: The major goal in your first year is to select a primary research mentor, who serves as your special committee chair. Because the nature of research varies among our concentrations, this process differs by concentration. A subset of first-year students who are interested in working with human or molecular nutrition faculty with wet laboratory-based research programs will participate in “laboratory rotations.” Students participating in rotations will spend three periods of 4-8 weeks each (depending on the nature of the project) working on projects in laboratories of interest. This allows incoming students to maximize their potential of finding the best fit for a “laboratory home” and to develop skills in a variety of laboratory techniques. For other concentrations that do not require rotations, you can learn about and compare different research groups by attending the research meetings of different professors, and by talking with the potential mentors and their current students. In all four concentrations, the special committee chair must be selected by the end of the first academic year.
Your selection of a research mentor should be based on the research topic as well as on the mentoring style of the faculty member thus keeping in mind the mentoring style that is most likely to support your success as a student. Another tip provided by current students is that what you study for your dissertation is unlikely to be what you study throughout your career. It is a good idea to keep in mind the type of training that you would like to prioritize for your doctoral training, understanding that all careers are built over time and the Ph.D. training is an important and key driver of your future.
The faculty, postdoctoral associates, technical staff, and graduate students have expertise in the physical, life and social sciences, and they are jointly committed to fundamental and multidisciplinary research and its translation to nutrition practice and policy.
