Dr. Beresford's research interests are in the areas of nutritional epidemiology and chronic disease prevention. Her work is specifically designed to improve the scientific basis for public health policy and recommendations concerning dietary intake, physical activity and intake of folic acid levels. She has been Principal Investigator on numerous individual and group randomized trials of dietary behavior intervention.
Dr. Beresford has been an investigator with the Women's Health Initiative since its inception, contributing to the intervention design in the Dietary Modification trial, and is lead author of one of the primary results papers of the randomized trial, namely the low fat dietary pattern and risk of colorectal cancer. She was a member of the Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health, National Academy of Sciences, 2002 - 2004, and an invited speaker at the Institute of Medicine's workshop on Managing Food-related Risks in 2005. She served as President of the American Epidemiological Society from 2007 to 2008.
Her research focus in the science of changing behavior on a population level has involved many interdisciplinary collaborations. The development and evaluation of obesity prevention interventions in worksites, using rigorous group randomized trial design and collaborative principles with participating worksites, provides one such example
