Degree Awarded: PHD

Exercise and Nutritional Sciences

With integrated disciplinary contexts, the PhD in exercise and nutritional sciences curriculum trains scholars and leaders to conduct high-impact, interdisciplinary research in exercise and nutritional sciences, to address exercise and nutrition-related health problems, and to develop effective physical activity, exercise and nutrition interventions. In contrast to other programs, this program integrates exercise, nutrition and health promotion research using a problem-centered, interdisciplinary approach. The exercise and nutritional science program emphasizes translational research, spanning from pre-clinical research aimed at understanding the biological mechanisms through which diet and exercise impact health and well-being, to clinical trials and the implementation of evidence-based practices in the community. Students work collaboratively with an approved mentor from the beginning to the end of the doctoral program and focus their research on one primary area of interest: translational metabolism and physiology, behavioral and community health sciences, or biomechanics and motor control. Students and faculty conduct high-quality, use-inspired research intended to reduce the physical, social and economic costs of unhealthy living. Students engage in research at every stage of the program through participation in research practicums, translational research teams, research seminars and colloquia, and dissertation research. After earning a master's degree, the program can be completed in four years with full-time study. The program also accepts part-time students.
