North Carolina State University

What you'll study

The PhD in Nutrition Sciences emphasises rigorous research training combined with advanced coursework in nutrition, metabolism and research methods. Students undertake a tailored programme of study that typically includes core and elective courses, laboratory rotations (for lab-based students), and a sustained dissertation research project under the supervision of a faculty advisor.

• Core topics: advanced human and molecular nutrition, nutrient metabolism, nutritional biochemistry, and physiology.
• Research methods: experimental design, biostatistics, epidemiologic methods, clinical trial methodology, and laboratory techniques relevant to nutrition research (e.g. molecular assays, metabolomics, tissue culture).
• Population and behavioural nutrition: nutrition epidemiology, community nutrition, public health nutrition policy and intervention design for populations.
• Electives and interdisciplinary options: nutrigenomics, food systems and policy, food safety and quality, food processing impacts on nutrition, and courses from allied departments such as public health, psychology, veterinary and biomedical sciences.
• Seminars and professional development: regular departmental seminars, grant-writing workshops, teaching practicums, and opportunities to present at conferences.
• Qualifying requirements: completion of required coursework, passing of departmental qualifying or comprehensive examinations, successful proposal and defence of a doctoral dissertation, and demonstration of original research through peer-reviewed publications or presentations.

Entry requirements

Applicants are normally expected to hold a recognised bachelor's degree in nutrition, dietetics, biology, biochemistry, public health or a closely related field; a relevant master’s degree may strengthen an application but is not always required. Successful applicants typically demonstrate strong academic preparation in the biological and quantitative sciences and relevant research experience.

• Academic transcripts: official records from all post-secondary institutions attended.
• Research experience: evidence of research aptitude such as laboratory or fieldwork, publications, posters or detailed descriptions of research projects.
• References: several letters of recommendation (typically two to three) from academic or professional referees who can speak to research potential.
• Personal statement: a statement of purpose outlining research interests, fit with faculty and career goals.
• CV or résumé: detailing academic background, research experience and technical skills.
• English language proficiency: for applicants whose first language is not English, a recognised English test is normally required unless exempted under university policy.
• Standardised tests: requirements for exams such as the GRE vary by programme and may not be required; consult the department for current policy.

Career prospects

Graduates of the PhD in Nutrition Sciences pursue a wide range of careers that build on intensive research training and disciplinary breadth.

• Academia and research: tenure-track faculty positions, postdoctoral fellowships and research scientist roles in universities and medical centres.
• Government and public health: research and policy roles in public health agencies, national and international nutrition programmes, and regulatory agencies.
• Industry and private sector: research and development, clinical research, product development and scientific affairs in food, nutrition and biotechnology companies.
• Clinical and translational research: leadership roles in clinical trials, hospital-based research programmes and translational teams linking basic science to patient and population interventions (note: clinical dietetic registration is a separate credential).
• Non-profit and global health: research, programme evaluation and leadership in foundations and NGOs focused on nutrition and food security.
