• Coursework: advanced seminars in clinical practice, epidemiology, research design, and data analysis.
• Clinical scholarship: supervised practicum and clinical teaching focused on evidence-based medical nutrition therapy and multidisciplinary care.
• Research: proposal development, comprehensive examinations, and a doctoral dissertation that contributes original knowledge to clinical nutrition or dietetics services delivery.
• Interdisciplinary opportunities: collaborations with departments such as public health, medicine, endocrinology and geriatrics to support translational research projects.

Entry requirements

Applicants are normally expected to hold a relevant master's degree (for example, in dietetics, nutrition, public health or a closely related biomedical discipline) or have an equivalent record of professional practice and research. Additional typical requirements include:

• A record of academic achievement at graduate level (e.g. strong transcript).
• Evidence of research potential, such as a master’s thesis, publications, or a substantive research project.
• Professional credentials where applicable, such as registration/licensure as a dietitian or nutritionist in the applicant’s country.
• A statement of purpose outlining research interests and proposed faculty supervisors, and letters of recommendation from academic or professional referees.
• For some applicants, demonstration of quantitative skills; programmes may require prior coursework in statistics or research methods if not already completed.

Standardised test requirements and minimum GPA expectations vary by programme and applicant background; prospective students should consult the university’s graduate admissions guidance for current details.

Career prospects

Graduates of a PhD in Dietetics and Clinical Nutrition Services go on to careers in academic and research institutions, clinical leadership and specialist practice, government and public health agencies, and the private sector. Typical roles include:

• University faculty and researcher, leading teaching programmes and independent research in clinical nutrition.
• Clinical director or chief dietitian in hospitals and health systems, overseeing nutrition services and quality of care initiatives.
