Dr. Jill Reedy is Chief of the Risk Factor Assessment Branch (RFAB) of the Epidemiology and Genomics Research Program (EGRP) in NCI's Division of Cancer Control and Population Sciences (DCCPS). Previously, she was a Program Director in RFAB from 2015-2019.

As Branch Chief, Dr. Reedy oversees EGRP’s research portfolio and initiatives that focus on dietary and physical activity assessment; methods, tools, technologies and resources for risk factor assessment; and obesity policy research. Her scientific interests include different methodological approaches in dietary pattern analysis, dietary surveillance, obesity policy, new technologies for dietary assessment, and measures of the food environment.

Dr. Reedy currently leads the Dietary Patterns Methods Project, a collaboration with investigators from three large U.S. cohorts, which aims to systematically examine index-based scoring systems using standardized methods with cancer mortality outcomes. She also partners with colleagues at NCI, the United States Department of Agriculture (USDA), and the National Collaborative on Childhood Obesity Research (NCCOR) to develop resources for researchers including the Dietary Assessment Primer; the NCCOR Measures RegistryExternal Web Site Policy, User GuidesExternal Web Site Policy, and Learning ModulesExternal Web Site Policy; the NCCOR Catalogue of Surveillance SystemsExternal Web Site Policy; and the Healthy Eating Index.

Dr. Reedy is a member of the Data Analysis Team for the 2020-2025 Dietary Guidelines Advisory Committee, and she has served in a similar capacity for past Dietary Guidelines. She serves on the Senior Leadership Group for the NIH Nutrition Research Task Force. She leads several trans-NIH working groups as well as the NIH Obesity Policy Research Grantees Network.

Prior to joining EGRP, Dr. Reedy was a Program Director and Nutritionist in DCCPS’s Applied Research Program (now the Healthcare Delivery Research Program). She first joined NCI as a Cancer Prevention Fellow. Dr. Reedy is a registered dietitian and previously worked as a Regional Manager at the Dairy Council of California, a consultant with the California Nutrition Network, and a pediatric dietitian.
