Professor of Mathematics and Statistics Liam O’Brien and Alane O’Connor ’96 have coauthored a paper published in the Journal of Maternal-Fetal & Neonatal Medicine. Titled “Implications of perinatal buprenorphine exposure on infant head circumference at birth,” their research shows that “head circumference in infants exposed to buprenorphine during pregnancy was not significantly different from national norms for either male infants or female infants.”
