Dr. Tucker is currently a member of the American Society for Nutrition executive board of directors, as chair of the Nutritional Sciences Council. She is also an associate editor for the Journal of Nutrition. For many years before moving to Northeastern, she was Professor and Director of the Dietary Assessment and Epidemiology Research Program at Tufts University. Her expertise lies in nutritional epidemiology, public health nutrition, and health disparities and nutritional status of high-risk populations. Katherine has authored and co-authored over 250 study publications, including research on dietary intake in African American adults, the traditional eating patterns of Puerto Rican adults, and Mexican American dietary patterns and obesity. In May 2010, Katherine and her team were awarded an NIH grant for a Center on Population Heath and Heath Disparities to study heart disease in Boston’s Puerto Rican community—a major event and continuation of her previous work within the Puerto Rican communities on chronic disease.
