Nutrition — Ph.D.

The Doctor of Philosophy (Ph.D.) degree in nutrition prepares students to effectively conduct nutrition research as well as apply nutritional science knowledge and appropriate research methods to address public health problems. The program provides an advanced curriculum in nutrition, professional skills, and competencies required to support careers in teaching and research. This program is uniquely situated in the School of Public Health at a health sciences university. The program engages in interdisciplinary research, encouraging collaboration across public health disciplines and the basic sciences, promoting and building upon its core legacy of vegetarian and plant-based nutrition. Areas of curricular strength and research emphasis include plant-based diets and the health of the individual, populations, and the planet; nutritional epidemiology; diet and chronic disease-risk reduction; and community nutrition.

Students enrolled in this program are able to concurrently complete coursework and practice experience necessary to sit for the registered dietitian nutritionist (RDN) exam if not already an RDN.

Program learning outcomes

By the end of the program, the graduate should be able to:

1. By the end of the program, graduates should be able to:

   1. Evaluate advanced knowledge in nutritional science and explain the biological mechanism underlying the relationship between nutrients, foods, and diet pattern and health.
   2. Critically evaluate the evidence base and advocate for the role of plant-based diets in promoting health of the individual, population groups, and the planet.
   3. Apply analytical and fundamental concepts in nutritional epidemiology.
   4. Apply principles of research ethics; conduct a research study that addresses a nutrition problem; collect/abstract, analyze, and interpret the data; and report findings.
   5. Effectively communicate nutritional science, orally and in writing, to the scientific community and the public, advancing the field and promoting public health.
   6. Use best-practice modalities in pedagogy to deliver educational experiences in an academic setting.

Individuals who may benefit from the program

Individuals seeking careers in:

• Academia (teaching and research).
• Researcher in private industry, governmental agencies, nonprofit organizations, or research institutes.

¹

Students are required to register for this course 3 times. 0 units in Autumn and Winter, and 1 unit in Spring.

²

Choose in consultation with academic advisor.  Must be graduate-level courses in nutrition, dietetics, public health, or basic sciences.

³

Students will take 1 unit at a time.

⁴

All courses are required for eligibility to sit for the RDN examination.  Courses completed in a prior program (either at the undergraduate or graduate level) will be evaluated on a course-by-course basis to determine equivalency; thus reducing the number of courses to be completed at LLU.  Consult with your advisor if you wish to pursue this option.

⁵

Completed units in NUTR 694 Research (maximum of 3) and NUTR 697 Dissertation Proposal(maximum of 3) will reduce NUTR 697 Dissertation Proposal units by the same amount. The maximum combined units for NUTR 694 Research and NUTR 697 Dissertation Proposal cannot exceed 3. Maximum combined units for NUTR 694 Research, NUTR 697 Dissertation Proposal, and NUTR 698 Dissertation must equal 12.

Fulfills service learning requirement

Noncourse requirements

Comprehensive and qualifying examinations

Students are required to demonstrate ability and readiness to proceed with doctoral study and research by successfully passing the comprehensive examination. Degree specific descriptions of the comprehensive examination can be found in the SPH Ph.D. Handbook.  

Advancement to candidacy

Advancement to candidacy is granted by the Academic Dean. When the required discipline specific and research methods courses are completed, the student must successfully pass a written comprehensive examination. The next step is the qualifying examination. The student is required to submit a concept paper describing the proposed dissertation research, and members of the proposed Dissertation Guidance Committee (DGC). Students are advanced to candidacy when they successfully defend (oral examination) their dissertation proposals. Proposal should include the first three chapters of the dissertation—Introduction, Review of Literature, and Methods. The details of this process are described in the SPH Ph.D. Handbook.

Teaching experience

All doctoral students are required to serve as a teaching assistant for a minimum of one quarter. Additional information is detailed in the SPH Ph.D. Handbook.

Professional development

All doctoral students are required to present their research work at a scientific conference either as a poster or as short oral presentation. 

Culminating experience

As a part of the culminating experience, the student publishes one manuscript in peer-reviewed journal (co-authorship or review article acceptable, can be from dissertation or non-dissertation related research), submits two publishable papers from their dissertation research for peer review, successfully defends dissertation, and submits a committee approved dissertation manuscript. Further details provided in the SPH Ph.D. Handbook.
