Nancy Potischman
Nancy Potischman, PhD, is a Nutritional Epidemiologist in the Office of the
Associate Director of the Applied Research Program. She received her BS in
Biochemistry from the University of Massachusetts and her PhD in Nutritional
Sciences from Cornell University. Dr. Potischman was involved in epidemiologic
research, particularly of female tumors, in the Division of Cancer Epidemiology
and Genetics at NCI from 1989 to 1999. Before joining the Division of Cancer
Control and Population Sciences in 2001, she was Associate Professor of
Epidemiology in the School of Public Health at the University of
Massachusetts.
Dr. Potischman's primary research efforts are focused on biomarkers of
nutritional status and hormonal factors related to cancer. She has conducted
methodological work for improved dietary assessment methods and laboratory
quality control issues. Nutritional exposures cover a range of dietary
instruments, biomarkers, and anthropometric indices. Methodological work has
included comparing estimates from commonly used dietary questionnaires to
serologic measures, as well as applications of new techniques to minimize
measurement errors. She is active in the NCI Measurement Error Working Group and
has experience with measurement issues related to physical activity,
anthropometric, and dietary assessment. Her current work involves developing
food frequency questionnaires for pregnant and lactating women, addressing how
to best assess diet in children, assessing diet in the distant past, and
developing an automated
self-administered 24-hour recall instrument. Another area of interest
involves evaluation of early life factors and risk factors across the life span,
in relation to each other, and in relation to cancer risk in adulthood.
