Amy F. Subar, PhD, MPH, RD, is a Research Nutritionist with the Risk Factor Monitoring
and Methods Branch in the Applied Research Program, having started as a Cancer Control
Fellow in 1990. She received a BS in Dietetics at the State University College at
Buffalo; an MPH at the University of Minnesota; and a PhD at Syracuse University. Her
research interests include developing, designing, and conducting nutrition research
related to dietary methods, dietary instruments, measurement error, dietary surveillance,
and nutritional epidemiology.
Dr. Subar directed the development and evaluation of the Diet History Questionnaire,
NCI's publicly available food frequency questionnaire. This work encompassed all areas of
questionnaire development: cognitive issues, methods to determine food and portion size
lists, methods for creating nutrient databases for frequency questionnaires, testing of
response rates, and comparative validation. This food frequency questionnaire has recently
been modified to be web-based and is freely available to investigators conducting
nutrition research. Dr. Subar's more recent research has focused on understanding
measurement error in the biomarker-based Observing Protein and Energy Nutrition (OPEN)
Study. Currently, Dr. Subar is leading a project to develop and validate a Web-based,
automated, self-administered 24-hour dietary recall using multimedia computer technology.
She is also a lead investigator in the AARP Diet and Health Study, the largest prospective
dietary cohort in the US.
Dr. Subar serves as a member of the Editorial Board of the Journal of the American
Dietetic Association and is a member of the American Dietetic Association and the American
Society of Nutrition. She has received three NIH Merit Awards.
