Pediatric Surgery Research

Faculty research interests in the Division of Pediatric Surgery of the Emory University School of Medicine include gastroesophageal reflux, quality and safety, advanced laparoscopic procedures in infants and children, liver disease, pediatric oncology, and bariatric procedures for adolescents.


Dr. Matthew Clifton

Matthew Clifton, MD

Dr. Clifton's research involves pediatric hepatobiliary disease and the application of clinical research to improve pediatric healthcare. He is co-PI of a study evaluating the accuracy of MRI guided laparoscopic pull-through for imperforate anus, the surgeon of record for an investigation of the infusion of liver cell suspension in children with urea cycle disorders, and the institutional surgical representative at Children's Healthcare of Atlanta for the Childhood Liver Disease and Research Education Network (ChiLDREN), which studies biliary atresia as well as a host of other childhood liver pathologies.

Dr. Mehul Raval

Mehul Raval, MD

As the director of research for the Division of Pediatric Surgery, Dr. Raval mentors medical students, pediatric surgery residents, and students from the Rollins School of Public Health. His own research interests include quality improvement, outcomes measurement, surgical safety, protocol development, and comparative and cost effectiveness assessment, with the overall focus of improving the value of children's surgical care by optimizing outcomes and decreasing costs for commonly performed surgical procedures.

In 2017, Dr. Raval received a $1.1M grant as principal investigator from the Agency of Healthcare Research and Quality to study the value of children's surgical care using payment data at children's hospitals as compared to non-children's hospitals for frequently performed surgical procedures. Dr. Raval hopes that his conclusions will encourage pricing transparency and cultivation of a high quality, value-centric healthcare system for all children in the U.S.

Dr. Stephanie Walsh

Stephanie Walsh, MD

Dr. Walsh is a co-investigator on several projects, including an evaluation of the benefits of support groups for bariatric adolescents, a prospective study of a camp-based program that promotes positive behavior change among overweight youth, an analysis of the effects of weight loss on resting metabolic rate in adolescents, and a study of the impact of weight loss on arterial health in morbidly obese adolescents.

Dr. Mark Wulkan

Mark Wulkan, MD

In his research, Dr. Wulkan, chief of the Emory Division of Pediatric Surgery, focuses on pediatric surgery outcomes and innovative therapies. His current projects include a prospective trial of adjustable gastric banding in obese adolescents, and development of a modified reflux procedure called cardiaplication to treat gastroesophageal reflux disease in infants. He is also engaged in multiple retrospective studies with other pediatric surgery faculty.
