College of Agriculture

Department of Nutrition, Dietetics and Food Sciences

MS and PhD Programs


Admission Requirements

Candidates for graduate study in the Department of Nutrition, Dietetics, and Food Sciences need a background in chemistry, biochemistry, physics, mathematics, statistics, bacteriology and physiology. Prior coursework in food science or nutrition is desirable. Students may be accepted into the NDFS graduate program with deficiencies in these areas; however, their supervisory committee will require that competence equivalent to a BS degree in Nutrition, Dietetics, and Food Sciences be obtained as part of the Program of Study.

Students must meet some departmental requirements, in addition to requirements of the School of Graduate Studies, as shown at: http://www.usu.edu/graduateschool/apply/

Departmental requirements include the following:

  1. Students must attain Graduate Record Examination (GRE) scores at the 40th percentile minimum on the Verbal, Quantitative, and Analytical Writing tests.
  2. Before acceptance into a PhD program, a student must have obtained an MS degree or have a manuscript reporting original research accepted for publication in a refereed journal.
  3. Before acceptance into the Department of Nutrition, Dietetics, and Food Sciences, potential MS and PhD graduate students must be accepted by a faculty member who is willing to add them to his or her research team.

Registration Requirements

Once admitted, students are required to maintain enrollment as follows:

  1. Enrollment in at least 3 credits per semester in order to use University facilities and receive direction (including thesis or dissertation direction) from their major professor.
  2. Enrollment in at least 9 credits per semester if receiving an assistantship or fellowship from Utah State University.
  3. Enrollment in no more than 6 credits per semester if employed full time by Utah State University.

Selecting a Major Professor

Initially, students are accepted into the department when at least one faculty member has expressed a willingness to add the student to his or her research team. By doing so, the faculty member guarantees at the time of acceptance that the student may work in his or her research program. However, offers of financial aid must be discussed directly with the faculty member. Students may choose as their major professor any faculty member who can and is willing to accommodate them.

Establishing a Supervisory Committee

A supervisory committee must be selected by the student in conjunction with his or her major professor during the student’s first semester as an NDFS graduate student. The major professor serves as the chair of the supervisory committee. A minimum of three members (at least two from the department) including the major professor are required for the MS program.

The Supervisory Committee Approval Form needs to be submitted to the department head by the 8th week of the first semester for MS students and the 15th week of the first semester for PhD students. The department head must approve the student’s committee and may add members. It is the student’s responsibility to meet with the proposed committee members to make certain they are able and willing to serve. The Supervisory Committee Approval Form is then forwarded to the dean of the School of Graduate Studies for final approval. (Note: The Supervisory Committee Approval Form may be found on the School of Graduate Studies website at: http://www.usu.edu/graduateschool/degree_completion/pdf/Committee.pdf.

Defining a Program of Study

Students should register for their first semester based on advise from their major professor. Students should then prepare a Program of Study in conjunction with their major professor. The Program of Study should ensure fulfillment of the minimum requirements for all NDFS graduate students (shown below) and also include other courses providing the background necessary to conduct their research.

Students need to schedule a meeting with their supervisory committee to discuss the proposed Program of Study by the end of the first semester for MS students and by the end of the second semester for PhD students. A copy of the proposed Program of Study should be given to each committee member several days prior to the committee meeting.

The purpose of the committee meeting is to secure the supervisory committee’s approval of the Program of Study. The committee will determine any deficiencies in core BS competencies or academic background. Students in the NDFS graduate program should have already taken undergraduate general chemistry, organic chemistry, biochemistry, algebra, and statistics. Although these courses may be taken as part of the graduate program, they will not be counted as graduate credit in the Program of Study.

The supervisory committee is responsible for ensuring NDFS graduate students have (or obtain during their program of study) the expected core competencies of NDFS bachelor’s degree graduates. This can be based upon transcripts of courses from prior studies, passing courses listed in the program of study (with a minimum grade of B), or by administering a written or oral examination.

The committee will also determine that the courses included in the Program of Study meet the minimum requirements for obtaining an MS or PhD in Nutrition and Food Sciences (as shown below). All members of the committee, as well as the department head, must sign the Program of Study Form before it is sent to the School of Graduate Studies. Registration for all subsequent semesters should be based on the approved Program of Study. Changes to the Program of Study require a letter written by the major professor to the School of Graduate Studies (with copies to all members of the committee and the department head) justifying the change.

The student may register for courses not listed on the Program of Study with approval of his or her major professor (especially if the student is receiving a research assistantship).

  4. Teaching. ITLS 7920 : 1 credit required for PhD; NDFS 6910  or NDFS 5250 : 2 credits required for PhD. (Credits in this area are not required for MS.)
  5. Other Graduate Courses. BS core competency courses taken at the 6000 level, or other USU courses approved for graduate studies, may be included. For MS, 5-11 credits are required; for PhD, 18-28 credits are required.
  6. Research. For MS, 6-12 credits of NDFS 6970  are required. For PhD, 34-45 credits of NDFS 7970  are required. If students desire to do research beyond the Program of Study requirements, they should register for Continuing Graduate Advisement.

Total Credits Required

For the MS degree, 30 total credits are required. For the PhD degree, 90 total credits are required (including the 30 credits taken for the MS).

Research Proposal

In consultation with the major professor, the student must choose a research area suitable for the MS thesis or PhD dissertation, and then prepare a research proposal. Research proposals should be written and approved by the end of the second semester for students completing the MS degree and by the end of the third semester for PhD students.

The content and duration of the proposed research should be appropriate for the degree. It is expected that MS research and coursework (including writing and defense of the thesis) should be completed within 2 years (24 months). The length of research being proposed for the PhD dissertation is dependent on the discovery by the student of a substantial level of new information that can be added to their field of specialization.

The proposal should include the following:

  1. Title
  2. Description of the problem, based on the most current literature
  3. Statement of the purpose of the intended research
  4. Research Plan
  5. List of references cited, presented in a form acceptable for publication in a scientific journal in the student’s field

The student prepares the research proposal under the guidance of the major professor. Once the research proposal is completed, it is the student’s responsibility to schedule a meeting with his or her supervisory committee, and to provide each committee member with a copy of the research proposal at least two weeks prior to the meeting.

During the committee meeting, the student is expected to provide an oral presentation of the proposed research, and discuss any regulated aspects of the research, such as hazardous materials, experimental animals, or human subjects. After all members of the supervisory committee have approved the research proposal, a copy of the proposal will be sent to the graduate school.

Departmental Seminar

The NDFS graduate seminar (NDFS 7800 ) is held in the Nutrition and Food Sciences Building, room 202 from 3:30 to 5:00 p.m. each Wednesday during fall and spring semesters. All NDFS MS and PhD students are expected to register for and attend this seminar during each semester for which they are enrolled as full-time graduate students.

This seminar will include presentations by NDFS faculty members, faculty members from other USU departments, invited speakers, and graduate students. In addition to the presentations, NDFS 7800  will also include assignments on topics such as critical thinking, scientific writing, poster preparation, and grant proposal writing. The theme of the seminar will be chosen by the NFS faculty member who is assigned as the course instructor.

During the semester in which they defend their thesis or dissertation, all MS and PhD students are required to give a presentation (a 30 to 45 minute seminar) on the results of their research. This presentation will be given to the NDFS faculty members and students as part of the NDFS 7800  seminar series. The student must invite all members of the supervisory committee to attend this seminar presentation. At the beginning of the semester in which they plan to defend their thesis or dissertation, students need to schedule a date for their presentation with the NDFS 7800  instructor.

Comprehensive Examination (PhD students only)

Before a student can become a candidate for the PhD degree, he or she must take a comprehensive examination, as required by the School of Graduate Studies. After completion of the courses listed in the Program of Study, the student should schedule a meeting of their committee for the comprehensive examination. This is usually an oral examination (although committee members have the option of providing a written exam), and the student should bring the Application for Candidacy for Doctoral Degree Form to the examination.

Typically students will be asked questions related to their area of specialization and their field of research. However, the comprehensive exam can also be used to test students’ overall knowledge of food science or nutrition, and committee members can ask any questions that will test the student’s knowledge and ability to synthesize nutrition and food science information, as well as answer questions. The form should be completed at this time. On the Application for Candidacy for Doctoral Degree Form, the committee members will list the field in which they examined the student, and then sign the form accordingly.

Thesis or Dissertation Final Examination

Students write the thesis or dissertation under the guidance of their major professor. To schedule a tentative date for the final examination (or defense) of the thesis or dissertation, students should also contact their supervisory committee members. Students need to plan well in advance, so that there will be sufficient time allowed for the student to complete their writing and for the committee members to read the thesis or dissertation. When the thesis or dissertation is ready to be defended, and at least four weeks prior to the tentative defense (or final) examination date and time, the student submits a copy to each committee member.

After the committee members have read the thesis or dissertation and have determined that it is indeed ready to be defended, the student prepares the Appointment for Examination Form. Each of the supervisory committee members is required to sign this form, indicating that they have read and tentatively approve the content and format of the thesis or dissertation, and that they can be in attendance at the defense.

The Appointment for Examination Form needs to be submitted to the School of Graduate Studies a minimum of 10 working days prior to the defense. The School of Graduate Studies will appoint one of the supervisory committee members (other than the major professor) to chair the defense examination.

Completing the Thesis or Dissertation

After a successful defense of the thesis or dissertation, the student is required to make any changes to the thesis or dissertation that are required as a consequence of the final examination. At this time, the student can schedule with the School of Graduate Studies a date by which he or she expects to have the thesis or dissertation available for review. If the thesis or dissertation is not submitted to the School of Graduate Studies prior to this date, it will be reviewed at the next available date.

When the thesis or dissertation has been revised to the satisfaction of the committee member(s) assigned the responsibility of ensuring such changes are completed to the satisfaction of the supervisory committee (usually the major professor), the front page of the thesis or dissertation can be signed. The student then completes the Thesis/Dissertation Format and Style Form and obtains the major professor’s signature (in the NDFS Department the major professor also acts as the departmental format/style reviewer) and submits the thesis or dissertation to the School of Graduate Studies.

Following review by the School of Graduate Studies, the thesis or dissertation is collected by the NDFS Department and returned to the major professor, along with a list of corrections. The major professor then has the responsibility of ensuring that the thesis or dissertation is revised (if necessary), and of signing a release indicating that the thesis or dissertation is ready for binding. The student may then make the needed copies of the thesis or dissertation and submit them for binding. It is also the student’s responsibility to ensure that all other forms and fees related to the thesis or dissertation and to the completion of his or her degree are finalized.
