Barbara A. Cohn, Director

Barbara A. Cohn is an epidemiologist who earned her PhD at the University of California, Berkeley in 1984. She became co-director of the Child Health and Development Studies in 1997 and director in 2001.

In addition to her responsibility as director of the Child Health and Development Studies, Dr. Cohn directs an active research program that addresses these questions:

  • How pregnancy protects mothers against breast cancer
  • How exposures in the womb affect the risk of cancer and other diseases
  • How exposures to environmental chemicals before birth affect the growth and reproductive health of men and women

Dr. Cohn studies how pregnancy protects against breast cancer. She is searching for natural protective mechanisms that can be used to prevent or treat breast cancer. She collaborates with CHDS staff scientists Piera Cirillo and Roberta Christianson in this work.

Dr. Cohn also studies the health effects of exposures to hormonally active environmental chemicals. She is investigating effects of environmental chemicals on breast cancer in CHDS mothers. She is also investigating the effects of exposures to environmental chemicals before birth on the reproductive health of CHDS daughters and sons who are now having children of their own. In a newly launched 3 Generations Study of Breast Cancer, Dr. Cohn is investigating how exposures to environmental chemicals in the womb affect the risk of breast cancer for daughters and growth and development of granddaughters.
