Ph.D. Programs

Ph.D. in Nutrition

Virginia Survey PhotoOverview

Faculty in the interdepartmental Nutrition Program come from:

– Animal Science

– Agricultural and Human Sciences

– Food, Bioprocessing, and Nutrition Science

– Prestage Poultry Science

 

The Nutrition Program is founded not only on advanced study in nutrition but also in related biological, physical and social sciences. Particular emphasis is given to the development of creativity in nutrition research. An individual program of courses, which includes certain core requirements, is developed for each student by an advisory committee.

Research activities are as diverse as the Nutrition faculty and range in level from the molecular to the whole animal, from the individual to the community. Students majoring in Nutrition are affiliated with and housed in one of the departments listed above. The choice of department, as well as faculty adviser, depends on the research interests of the student.

Research programs are primarily in the area of nutritional biochemistry or experimental animal nutrition (e.g. horses, ruminants, swine, poultry, rodents, and other species), or community nutrition and public health.

Graduates find employment in academia, government, industry, and non-profit organizations, or continue their education in medical and allied health fields.

Coursework

A minimum of 72 credit hours of courses and research, including credits transferred from a Master degree, at least 20 credits in specified nutrition and biochemistry courses, and advanced coursework in related departments. The Ph.D. is a research intensive degree culminating in a dissertation. Written and oral preliminary examinations in the major and minor fields are scheduled no earlier than the end of the second year of graduate study and not later than one semester before the final oral examination. These exams for admission to candidacy are administered by the student’s advisory committee.

Research Advisors

If an applicant qualifies for admission, the Coordinator and the Graduate Admissions Committee will secure a member of the Nutrition faculty to serve as an advisor prior to final admission. Applicants for M.S and Ph.D. degrees are encouraged to contact the following faculty in the departments with similar interests to discuss research advising.

Internships

Internships can be a valuable educational experience and preparation for future employment. However, interrupting research progress for internships and coops often leads to a delay in the time required for the degree. In most cases there are limits to the number of semesters that research assistantships and tuition benefits can be paid. Some research projects involve industry cooperation, or opportunities to be involved in projects in remote locations. NC State offers special non-curricular training, such as Preparing the Professoriate, and Certificate of Accomplishment in Teaching, through the Graduate School; participation in these programs can coincide with research and course work.

Testimonials

My name is Maryanne Perrin and I’m a doctoral student in Nutrition Science at North Carolina State University.

I have a BS Industrial Engineering and an MBA, but have always loved food (growing it, cooking it, and eating it!).  As I headed down the path of changing my career focus to nutrition science, NC State ended up being the best fit for me because I wanted a strong biochemistry-based foundation for my understanding of nutrition and human health.

My research is focused on expanding the supply of pasteurized donor milk, a life-saving food/medicine, for fragile infants. While Dr. April Fogleman is my major advisor, I have had the pleasure of working with at least a half dozen faculty in the department and across campus in the pursuit of my research. This work has allowed me to get exposure to both quantitative research methods (studying the composition of human milk in a lab setting) and qualitative research methods (using traditional qualitative research tools as well as new techniques using social media).

From the day I started the program my advisers have encouraged me and given me the time and space to find a research topic that I was passionate about, which is something I especially appreciate about this program. After graduation, I plan on either teaching at the university level or working in the field of public health.
