Marian L. Neuhouser, Ph.D., R.D.

Dr. Marian L. Neuhouser, a nutritional epidemiologist, leads Fred Hutch’s Cancer Prevention Program, the first such National Cancer Institute–funded program in the U.S. Her research focuses on the role of nutrition and energy balance (obesity) in the prevention and survivorship of breast and prostate cancers and other diet-related chronic diseases. She has led or co-led studies ranging from feeding trials to large, population-based studies, including those that are focused on minorities, the elderly and those experiencing health disparities. Her research also focuses on ways to improve how scientists measure and track diet and physical activity among study participants. For example, Dr. Neuhouser is interested in the extent to which novel biological markers of food intake, such as metabolomics, can improve upon self-report measures, such as when participants keep a food journal or fill out a food questionnaire — methods known to have substantial measurement error.
