Dr. Edmond D. Shenassa was recruited from Brown University in 2008 to become the founding director of the Maternal and Child Health (MCH) program in the department of Family Science. With a dual doctorate in Epidemiology and MCH from Harvard School of Public Health and a master’s in quantitative research methods from UCLA, Dr. Shenassa’s population-based investigations focus on social determinants (eg, income inequality, housing quality) of health over the life course. He also investigates the synergy between modifiable determinants of prenatal and perinatal health (eg, breastfeeding by smokers). Much of this work is based on data Dr. Shenassa collected as the Principal Investigator of the Rhode Island Birth cohort study, an investigation of in-utero exposure to toxins and physical, cognitive, and social development during infancy. His team recruited 650 women who were one-day post-partum and measured physical, mental, and behavioral outcomes of the mother-infant dyad on three occasions during a 15 month follow-up period. This work has been funded by Maternal and Child Health Bureaus (HRSA), Centers for Disease Control and Prevention, Flight Attendant’s Medical Research Institute, and Environmental Protection Agency.
