Study Center: Arkansas
The Arkansas Center for Birth Defects Research and Prevention is a collaboration between the University of Arkansas for Medical Sciences and the Arkansas Reproductive Health Monitoring System at Arkansas Children’s Hospital. The Arkansas Center has been and is supported by the Centers for Disease Control and Prevention as a Center for Excellence in Birth Defects Research.
The Arkansas Center’s mission is to reduce the prevalence of birth defects in Arkansas and the nation and to reduce the economic, social, and psychological impact of birth defects at a state and national level. To accomplish this goal, the Center conducts research on the etiology and prevention of birth defects through the successful completion of high-caliber epidemiologic studies.

Wendy Nembhard, MPH, PhD
Director
Wendy Nembhard, MPH, PhD is the current Principal Investigator (PI) and the Director of the Arkansas Center for Birth Defects Research and Prevention at the University of Arkansas for Medical Sciences. Dr. Nembhard is also a tenured Professor and Chair of the Department of Epidemiology at Fay W Boozman College of Public Health at the University of Arkansas for Medical Sciences (UAMS) and a tenured Professor in the Department of Pediatrics, UAMS College of Medicine. She joined the Center as a Co-Investigator in 2014 and became the Center Director in 2017. She has more than 25 years of experience in birth defects research, including serving as the Scientific Director of the Arkansas Reproductive Health Monitoring System, the state’s birth defects registry from 2014 until 2018. Her research interests focus on the etiology of and long term-outcomes for children and adults with birth defects with a particular interest in congenital heart defects. As PI and Director, she oversees the analyses and dissemination of NBDPS data, storage and analyses of the biological samples, participation in the BD-STEPS, and the research activities of the Center.
Charlotte Hobbs, MD, PhD
Former Director
Charlotte Hobbs, MD, PhD was the Director of the Arkansas Center for Birth Defects Research and Prevention from the Center’s establishment in 1997 until her retirement from at the University of Arkansas for Medical Sciences in 2017. She was the recipient of the Pamela D. Stephens Endowed Chair for Birth Defects Research and Chief of the Section of Birth Defects Research in the Department of Pediatrics in the College of Medicine at the University of Arkansas for Medical Sciences. Dr. Hobbs’ primary research interests were the genetic and gene-environment factors that influence the development of congenital heart defects in the fetus. She led several studies on the genetic epidemiology of congenital heart defects using data from the NBDPS. Dr. Hobbs continues to collaborate with the Center on NBDPS projects.
