Doctorate in Nutritional Sciences

Our PhD in Nutritional Sciences emphasizes research and application of research ranging from basic molecular and cellular sciences to clinical and community applications. Students enter our program with either a bachelor’s degree in nutrition or a master’s degree in nutrition or a closely related discipline. Graduates are prepared for careers in higher education, industry, healthcare and governmental programs. 


The program focuses on research and students gain extensive experience in their areas of choice. All students take a core set of classes, including macronutrients and micronutrients in human nutrition, research methods, statistics for experimenters, emerging topics in nutrition and grant writing.


Beyond core classes, students work with faculty advisors to develop individual plans of study to meet their goals. The program offers specializations in bioinformatics, community/public health nutrition, molecular biology, statistics and more. All students participate in research and complete 15 to 40 dissertation hours.


Students entering with a master’s degree must complete 60 hours of coursework. For those with a bachelor’s degree, 80 hours are required, and students earn the master’s degree after successfully completing 30 credit hours. 


Research and Faculty

All graduate faculty possess a PhD and/or Registered Dietitian credentials and integrate personal experiences and research into the curriculum. The department’s robust research portfolio includes the role of micronutrients in cancer, diet effects on the microbiome, international nutrition, metabolic risk indicators, nutrition and fitness for military and first-responders and obesity prevention programs and policy.
