Barbara A. Cohn, PhD

Principle Investigator

Barbara A. Cohn, PhDBarbara Cohn is the Director of the Child Health and Development Studies. Dr. Cohn is an ardent supporter of public university education. Professionally, Dr. Cohn has been studying the early life determinants of women's and men's health across the lifespan. She has studied environmental predictors of fertility and cancer, the relationship of pregnancy to health across the life-span including cardiovascular disease and cancer. Dr. Cohn is passionate about the link between sound research and strategies to improve public health. Dr. Cohn has dedicated her scientific career to producing needed information for development of better policies and programs, believing that good intentions are insufficient to bring about meaningful improvements to health. Ironically, Dr. Cohn's husband of 30 years, a professor at UC Berkeley, died of lymphoma four years ago following three years of severe illness and treatment. Now a widow touched by cancer, Dr. Cohn is even more strongly committed to make a difference by identifying options for cancer prevention starting now. She has three grown children, two who are also CAL Bears and one a UC Davis Aggie. In her spare time, Dr. Cohn loves to be outdoors, hiking with her three dogs Jake, Bandit, and Camilu. All the dogs help her at the office.

Piera Cirillo, MPH

Senior Research Scientist

Piera Cirillo, MPHPiera Cirillo is a Senior Research Scientist with the Child Health and Development Studies. She has worked with the study for over 20 years and has played an integral role in the conception, planning and implementation of the Three Generations Study. Piera was a Peace Corps volunteer in Nepal and later worked at The Salk Institute for Biological Studies isolating steroid receptors for the glucocorticoid hormones before getting her Masters in Public Health in Epidemiology. She is interested in continuing and contributing to the priceless legacy of Dr. Yerushalmy, who began the study in 1958. She believes that the CHDS mothers, fathers, sons, and daughters have a remarkable story to tell. Theirs is a story that provides clues about what behavior and what exposures might be linked to health. It will inform scientists about possible new treatments and methods of disease prevention. She is excited about re-connecting with the adult sons and daughters and their children in new studies that are currently in progress. The CHDS children's children will provide the opportunity to gain insight about the intergenerational transmission of disease and about the interaction between genes and environment. Piera enjoys running with her border collie, Tucker and cooking, eating and spending time with her family.
