Her research includes studies on the effect of adversity on children’s psychobiology and health. She has also studies the effect of child care health and mental health consultation on the quality of care in child care programs. She developed the CCHP Health and Safety Checklist, based on the key National standards, which is used by health consultants in 8 states as an assessment tool. Dr. Alkon is the����Chair of the National Association of Pediatric Nurse Practitioners (NAPNAP) child care special interest group and NAPNAP liaison to the AAP Section on Early Education and Child Care.

Sharon Sagiv, PhD

Assistant Adjunct Professor of Epidemiology(510) 642- 8917Dr. Sagiv is an Assistant Adjunct Professor of Epidemiology in the School of Public Health at UC Berkeley. She is an environmental epidemiologist with research interests focused primarily on the impact of prenatal and early life exposure to environmental toxicants on child development, including neurodevelopment. Much of Dr. Sagiv’s work to date has focused on prenatal exposure to persistent organic pollutants (POPs), including polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and polyfluoroalkyl chemicals (PFCs) and their associations with behavioral development in children. She has also investigated associations with heavy metals, including mercury, lead and manganese. A particular focus of Dr. Sagiv’s work has been on studying the association of toxicants with continuously distributed traits related to developmental disorders in childhood, including attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders (ASD).
