Dr. Sonia Vega-López has PhD in Nutritional Sciences from the University of Connecticut (2002) and completed her postdoctoral training in the Laboratory for Atherosclerosis and Metabolic Research at UC Davis Medical Center (2002-2003) and the Cardiovascular Nutrition Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (2003-2006). She is currently an Associate Professor of Nutrition at the School of Nutrition and Health Promotion, Arizona State University. Dr. Vega-López is a bilingual and bicultural researcher, native of Mexico. Her research focuses on studying lifestyle factors, particularly those related to diet and physical activity, and how to modify them for the prevention of chronic diseases among Hispanic individuals. During her doctoral studies and post-doctoral training, her research focused on conducting controlled interventions to assess the metabolic effects of specific dietary factors on cardiometabolic disease risk, lipoprotein metabolism, inflammation, and oxidative stress. More recently her work involves (1) studying how diet quality and physical activity affect chronic disease risk in minority and underserved populations; (2) designing and implementing culturally-tailored diet and physical activity interventions for chronic disease reduction among Hispanic families; and (3) assessing the effect of community-based interventions on biomarkers of disease risk.

Research Interests

  • Nutrition and health disparities
  • Evaluation of the effects of diet and lifestyle modifications on chronic disease risk factors, obesity, the metabolic disease and diabetes management
  • Assessment of diet quality and its role in cardiometabolic health among Hispanic individuals
  • Development of culturally sensitive strategies to aid Hispanics and other high-risk populations in chronic disease prevention
  • Effect of diets and dietary components on the metabolism of cholesterol and lipoproteins
