University of Hawaii at Manoa

What you'll study

The programme combines advanced coursework with independent research leading to a doctoral dissertation. Core topics cover nutrient metabolism and molecular nutrition, epidemiology and biostatistics, research methods, and advanced topics in community and public health nutrition. Students typically study modules in:

• Molecular and Cellular Nutrition — nutrient–gene interactions, metabolic regulation, and laboratory methods in nutritional biochemistry.
• Nutrition Epidemiology and Biostatistics — study design, dietary assessment methods, statistical analysis for population studies.
• Community and Public Health Nutrition — programme planning, evaluation, policy, and interventions targeted to diverse populations including Indigenous and Pacific communities.
• Food Systems and Sustainable Nutrition — food security, local food systems, and the links between agriculture, environment and diet quality in tropical settings.
• Advanced Research Methods — qualitative and quantitative methods, clinical trial design, and ethical conduct of research.

Students work closely with a faculty advisor to develop a tailored course plan, pass a qualifying examination or candidacy milestone, and complete a doctoral dissertation that contributes original findings to the field. Training options include laboratory-based research, community intervention studies, population surveillance and policy analysis, and interdisciplinary projects with collaborators across the university, including clinical and agricultural research centres.

Entry requirements

Applicants are normally expected to hold a relevant master's degree (for example, MSc or MPH in nutrition, public health, biomedical sciences, or a closely related field) or demonstrate equivalent research experience. Exceptional candidates with a strong bachelor's degree and substantial research background may also be considered. Typical application materials include:

• Academic transcripts from all post-secondary institutions attended
• A detailed curriculum vitae or résumé outlining research experience
• A statement of purpose describing research interests and potential faculty mentors
• Letters of recommendation (usually two to three) from academic or professional referees
• Samples of scholarly work or a research proposal, where requested
• Demonstration of English language proficiency for applicants whose first language is not English

Admission is competitive and selection prioritises demonstrated research potential and fit with faculty expertise. Some projects may require specific laboratory skills or prior coursework in biochemistry, physiology, or statistics.

Career prospects

Graduates of the PhD in Nutrition Sciences pursue a range of careers in academia, government and the private sector. Common career paths include:

• University faculty and principal investigators leading independent research programmes
• Research scientists in public health agencies, national health departments or international organisations focused on nutrition and non-communicable disease
• Senior roles in non-governmental organisations addressing food security, maternal and child nutrition, and community health
• Research and development positions in the food and biomedical industries, including product development, clinical research and regulatory science
• Policy analysts and advisors working on nutrition policy, programme evaluation and health systems strengthening
• Extension and applied research roles combining community engagement with translational research, especially relevant in regional and Pacific Island contexts

Graduates are well placed to lead interdisciplinary teams, secure research funding, and translate scientific evidence into policy and practice.
