Dr. Guenther is a Research Professor in the Department of Nutrition and Integrative Physiology, College of Health, University of Utah. She is also an Adjunct Professor in the Department of Biomedical Informatics, School of Medicine. From 2003 to 2013, she was a nutritionist at the US Department of Agriculture’s Center for Nutrition Policy and Promotion, where she led the 2005 and 2010 revisions of the Healthy Eating Index and conducted other research related to dietary assessment and the Dietary Guidelines for Americans. Earlier Dr. Guenther was employed by the USDA Agricultural Research Service, where her work focused on developing improved methods for collecting and analyzing dietary survey data. Dr. Guenther received her B.S. and M.S. degrees in nutrition from Case Western Reserve University in Cleveland, Ohio, and her Ph.D. in Nutritional Sciences from the University of Maryland, College Park. She completed an internship in clinical dietetics at the University of Michigan Medical Center. Dr. Guenther is a registered dietitian and served on the editorial board of the Journal of the Academy of Nutrition and Dietetics from 2004 to 2021.

Research Statement
