Case Western Reserve University

What you'll study

The doctoral programme combines advanced coursework, mentored research and professional development to train scholars in the biological, molecular and population-level aspects of nutrition. Early years emphasise core knowledge in nutrient metabolism, molecular nutrition, nutritional biochemistry, and methods in nutrition research, while later years focus on dissertation research and dissemination.

• Core coursework: advanced human nutrition, nutrient metabolism, nutritional biochemistry, molecular nutrition, and systems-level physiology.
• Methods and quantitative skills: biostatistics, epidemiologic methods in nutrition, clinical research methods and study design, laboratory techniques (e.g. stable isotope methods, metabolomics), and data analysis.
• Specialist topics: nutritional epidemiology, public-health nutrition, clinical nutrition and disease-related nutrition (obesity, diabetes, cancer), micronutrient biology, and the gut microbiome as it relates to nutrition.
• Research training: students undertake mentored laboratory or population-health research under a primary advisor, with opportunities for rotations in different labs and collaboration across departments.
• Seminars and professional development: journal clubs, departmental seminars, grant-writing workshops, teaching assignments and opportunities to present at national and international meetings.
• Degree milestones: completion of required coursework, passing qualifying or comprehensive examinations, a proposal/defence of dissertation research, and the submission and defence of an original doctoral dissertation.

Entry requirements

Applicants are expected to hold a relevant bachelor’s degree; many successful applicants hold a master’s or equivalent research experience. A strong foundation in the biological sciences, chemistry, nutrition, or public health is typically required. Competitive candidates present evidence of research experience and quantitative skills.

• Academic record: undergraduate degree with solid grades in relevant coursework (biology, chemistry, biochemistry, physiology or public-health/epidemiology courses).
• Research experience: prior laboratory or field research is strongly recommended; applicants should highlight any publications, abstracts or substantial projects.
• Application materials: transcripts, current CV, statement of purpose describing research interests and fit with faculty, and several letters of recommendation from academic or research supervisors.
• Standardised tests and English language: requirements for tests such as the GRE may vary by year or programme; international applicants must demonstrate English proficiency through recognised tests unless exempt.
• Interview/fit: admission is frequently based on research fit with available faculty mentors; applicants may be invited for interviews or meetings with potential advisors.

Career prospects

Graduates of the PhD in Nutrition Sciences pursue diverse careers in academia, clinical research, industry, government and non-profit sectors. The programme equips students to lead hypothesis-driven research, teach at university level, and translate nutrition science into policy or product development.

• Academic and research careers: university faculty, principal investigators in basic, translational or population nutrition research, and postdoctoral researchers.
• Clinical and hospital research: research scientist roles in clinical nutrition centres and hospitals; note that clinical dietetics practice requires separate professional credentialing where applicable.
• Industry: R&D and scientific leadership in food and beverage companies, nutraceuticals, biotechnology firms and contract research organisations.
• Government and policy: positions in public-health agencies, regulatory bodies and non-governmental organisations focused on nutrition policy, surveillance and programme evaluation.
• Other roles: science communication, grant management, and consulting in nutrition-related fields.
