Jessica Alvarez, PhD, RD, is Assistant Professor in the Division Endocrinology, Metabolism and Lipids of the Department of Medicine at Emory University School of Medicine. Dr. Alvarez is a registered dietitian with a Master's in Clinical Nutrition and a PhD in Nutrition Sciences from the University of Alabama at Birmingham. Dr. Alvarez's research focuses on the role of nutrition and body composition on metabolism in chronic diseases, including cystic fibrosis and cystic fibrosis-related diabetes, type 2 diabetes, cardiovascular disease, and obesity. Her research integrates state-of-the-art metabolomics with many aspects of nutrition research including rigorous clinical trials, body composition and fat distribution analysis, biomarker assessment, analysis of dietary intake and physical activity. Specific research foci include: 1) use of plasma high-resolution metabolomics (HRM), redox, and bioenergetic assessment to identify targets for nutritional intervention to optimize health in adults with cystic fibrosis and cystic fibrosis-related diabetes, 2) use of HRM to differentiate individuals with varying subtypes of body composition, such as normal weight obesity and central obesity, 3) role of dietary supplements in sulfur/disulfide thiol redox, insulin sensitivity, vascular function, and clinical outcomes in the general population and various clinical diseases (e.g., cystic fibrosis, prostate cancer, and osteoporosis), and 4) role of diet in sulfur/disulfide thiol redox-mediated pathophysiology. Dr. Alvarez is currently supported by a NIH/NIDDK K01 grant entitled, 'Integration of Nutritional Metabolomics with Bioenergetics in Cystic Fibrosis.
