Christopher W. Bartlett, PhDChristopher W. Bartlett, PhD, Principal Investigator, Assistant Professor of Pediatrics,The Research Institute at Nationwide Children's Hospital & The Ohio State University. My laboratory seeks to identify genetic factors for language impairments. As animal models of language development are of limited utility, we examine DNA from families segregating specific language impairment or autism as part of two separate but interacting projects. These projects are heavily interdisciplinary, utilizing a wide range of molecular and computational methods developed in-house and through close collaborations with experts in statistics and computer science. We hope that use of genetics will allow for identification of at-risk children to promote early intervention.

Stephen A. Petrill, PhDStephen A. Petrill, PhD, Professor of Psychology, The Ohio State University, received his MA and PhD from Case Western Reserve University and his BA from the University of Notre Dame. He completed his postdoctoral studies at the Social, Genetic, and Developmental Psychiatry Research Center, Institute of Psychiatry, London, UK. Dr. Petrill has examined the genetic and environmental contributions to developmental delays; including reading disability, math impairment, and language problems. He is principal investigator on the Western Reserve Reading and Math Projects. WRRMP involves longitudinal assessment of approximately 1000 children whose cognitive, social, and academic skills are tracked from kindergarten through adolescence. Dr. Petrill is also an associate editor of the Journal of Child Psychology and Psychiatry and is the former chair of the Behavioral Genetic and Epidemiology Review Panel at the National Institute of Health. Dr. Petrill is leading efforts to recruit and assess children and their families for the Biology of Language Study.
