Dr. Lynn T. Singer is a developmental psychologist whose research focus has been on high risk conditions of infancy and effects on child development as well as family processes. Most recently her focus has been on developmental neurotoxicology and effects of maternal drug use during pregnancy and child outcome, especially cocaine, alcohol, MDMA (ecstasy) and opioids. She has directed a number of large, NIH and privately funded research programs including: a 19-year study of high-risk, preterm infants with lung disease and their families; a longitudinal study of cocaine-exposed infants; and a birth cohort study of MDMA exposure. She has edited two books, Psychosocial Assessment of Adolescents and Biobehavioral Assessment of Infants, and authored more than 200 peer-reviewed articles in the medical and psychological literature. In 1997, the Case Western Reserve School of Medicine named her a “Million Dollar Professor.” She is an elected fellow of the AAAS, APS and APA.

Singer was also PI of the first NSF funded ADVANCE Institutional Transformation grant to a private university to develop programs to reduce barriers to advancement for women faculty in STEM fields, followed by NSF funded grants with Professor Diana Bilimoria, to develop, first, a Northeast Ohio consortium to bring university leaders together to advance STEM faculty initiatives, IDEAL (Institutions Developing Excellence in Academic Leadership) and then, a national consortium, IDEAL-N).

Singer’s career also included administrative appointments, serving as Vice-provost for Planning and Assessment, Interim Provost twice, Interim vice-president for Medical Affairs, Interim Dean of Graduate Studies, and Deputy Provost and Vice-president for Academic Affairs.
