The committee comprises expert scientists from epidemiology, oncology, pathology, medicine, public health, statistics, biology, toxicology and related fields to identify cancer-causing chemicals. They review and discuss hazard identification documents, evidence and public comments, then vote on whether to add a chemical to the Proposition 65 list, a database of information about chemicals known to cause cancer or birth defects or other reproductive harm. The scientists may also suggest and prioritize chemicals for future review.

Prior to joining the Keck School in 2001, Stern was a postdoctoral fellow at the National Institute of Environmental Health Sciences. She is a member of the American Association for Cancer Research and earned a Doctor of Philosophy degree in cancer biology from the University of Texas, MD Anderson Cancer Center, and a Master of Science degree in biology from the University of Buenos Aires School of Science.
