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 diet, physical activity, and sleep 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 is the program officer for the Diet Assessment Center for the Nutrition for Precision Health, powered by All of Us Research Program, which focuses on improving diet assessment methodologies through validation, evaluation, and modeling efforts. She also 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. Dr. Reedy serves on several trans-NIH working groups, including the Senior Leadership Group for the NIH Office of Nutrition Research.

Dr. Reedy partners with colleagues at NCI, the United States Department of Agriculture (USDA), the National Collaborative on Childhood Obesity Research (NCCOR), World Cancer Research Fund (WCRF), and the American Institute for Cancer Research (ACIR), to develop resources for researchers including the Dietary Assessment Primer; the NCCOR Measures Registry Resource SuiteExternal Web Site Policy; the NCCOR Catalogue of Surveillance SystemsExternal Web Site Policy; the WCRF/AICR Score; and the Healthy Eating Index.

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 Fellowship Program fellow. Dr. Reedy is a registered dietitian nutritionist and previously worked as a regional manager at the Dairy Council of California, a consultant with the California Nutrition Network, and a pediatric dietitian.
