Military dietitians are engaged in a variety of research projects at any given time. Some dietitians are assigned to work on research exclusively, such as the dietitians of United States Army Institute of Environmental Medicine (USARIEM) of Natick, Massachusetts. Other dietitians are finding fresh opportunities for research in deployed environments. The GPN includes research as a fundamental goal for each student.
The GPN's professional involvement in the field of nutrition includes publications, poster sessions, invited lectures, and grant activities. They are published in a variety of journals such as the Journal of the Academy and Dietetics, Diabetes Educator, Military Medicine, and Therapeutic Advances in Gastroenterology. Topics range from weight, lifestyle and behavior change, diabetes, Joint Field Nutrition Operations, performance nutrition, and minerals and nutritional status.
