John P. Ackerman, PhD, currently serves as the Suicide Prevention Coordinator for the Center for Suicide Prevention and Research (CSPR) at Nationwide Children's Hospital. He directs community, school, and hospital efforts to educate others about the risks and warning signs of pediatric suicide. The CSPR promotes evidence-based strategies to support individuals at risk for depression and suicide. Dr. Ackerman and his team are passionate about reducing the devastating impact of suicide on the community.

Dr. Ackerman obtained his Ph.D. in clinical psychology from the University of Delaware (2006) funded by an NIMH grant to study how disruptions in child-caregiver relationships influence children’s social and cognitive development. Dr. Ackerman subsequently completed his postdoctoral fellowship at the University of Maryland School of Medicine (2008) investigating the effects of prenatal drug exposure through adolescence. From 2008 to 2015, Dr. Ackerman served as a clinical psychologist on the Mood and Anxiety Program at Nationwide Children's. He supported the expansion of services for adolescents with mood disorders and served as child clinical psychology fellowship training director. Dr. Ackerman has contributed to ongoing investigations at The Research Institute at Nationwide Children's regarding risk factors for adolescent suicide. He examines how aspects of brain functioning (e.g., executive functioning, decision-making, emotion regulation) influence teens’ risk for suicidal behavior.
