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.
