Dr. Karla Au Yeung is an assistant professor of pediatrics at the Johns Hopkins University School of Medicine. Her areas of clinical expertise include pediatric gastroenterology and nutrition and inflammatory bowel disease.

Dr. Au Yeung received her medical degree from the Indiana University School of Medicine in 1994 and went on to complete her pediatrics residency training at Walter Reed Army Medical Center in Washington, D.C. She worked as a general pediatrician in Fort Bragg, North Carolina, for two years before returning to Walter Reed Army Medical Center for fellowship training in pediatric gastroenterology.

In 2002, she was appointed chief of pediatric endoscopy unit at Walter Reed Army Medical Center, supporting the advancement of technology for pediatric GI procedures, and later was promoted to assistant chief of the Division of Pediatric Gastroenterology and Nutrition. Her influential work in the pediatric residency at Walter Reed Army Medical Center garnered professional attention and led to her appointment to associate pediatric residency program director.

Dr. Au Yeung led the Pediatric Feeding Team Clinic at Walter Reed Army Medical Center, serving from 2005 to 2008 as medical director. During her tenure, she became interested in neonatal gastroesophageal reflux and swallowing disorders that occur in infants born prematurely. In addition, she has worked with children of all ages who have chronic gastroesophageal reflux disease with associated respiratory complications or eosinophilic esophagitis.

She has experience in modalities such as endoscopy and pH and impedance monitoring to better define and manage gastroesophageal reflux disease in children. Dr. Au Yeung joined the Division of Gastroenterology and Nutrition at the Johns Hopkins Children’s Center in 2008. more
