Research Overview

Dr. Cleves is a Professor of Pediatrics at the University of Arkansas for Medical Sciences (UAMS), College of Medicine, and a Senior Biostatistician at the Arkansas Center for Birth Defects Research and Prevention. Dr. Cleves received his doctorate degree in Biostatistics from the University of Oklahoma Health Sciences Center, and he completed his post-doctoral training in Statistical Genetics at Case Western University. His current research interests focus on discerning the genetic and environmental causes of major structural congenital malformations, particularly neural tube and congenital heart defects. Dr. Cleves is also involved in the assessment of quality and outcomes of pediatric health services as well as the assessment of interventions intended to modify health care provider behavior.

As Co-Investigator on the National Birth Defects Prevention Study (NBDPS), funded by the Centers for Disease Control and Prevention (CDC), Dr. Cleves analyzes the data collected about environmental and genetic risk factors for 30 structural birth defects. As of the spring of 2006, over 3,000 Arkansas families have participated in the NBDPS. He is also the co-investigator for a study on folate metabolism and birth defects funded by the National Institute for Child Health and Human Development. This local study investigates nutritional, lifestyle, and metabolic factors that affect the fetal environment. Using maternal interviews and DNA collected from infants affected by congenital heart defects and from their parents, this research team is seeking a greater understanding of the underlying mechanisms causing these defects.
