Professor James J. McKenna, Ph.D. is the Rev. Edmund P. Joyce CSC Chair in Anthropology and Chair of the Department of Anthropology at the University of Notre Dame. He also directs the Mother-Baby Behavioral Sleep Laboratory at the University. He has published extensively on infant sleep, breastfeeding, Sudden Infant Death Syndrome (SIDS), and the evolution of human behavior with special emphasis on the differences between the behavior and physiology of solitary and co-sleeping-breastfeeding mother-baby pairs. His interests include how cultural factors influence infant and childcare practices, which in turn, affect maternal-infant health and well-being. The National Institutes of Child Health and Human Development fund his research. Currently, he is involved in a multi-site USA national prospective project examining first-time teen moms throughout their pregnancies and throughout the first three years of their infants' lives. His articles have appeared in refereed periodicals and academic journals around the world, and he is considered one of the leading authorities on scientific studies of infant-parent co-sleeping and breastfeeding, especially bed-sharing, having been the first to study the practice.
