LITTLE ROCK, AR. (April 15, 2024) – Dr. Jennifer S. Guimbellot has joined Arkansas Children’s Hospital and the University of Arkansas for Medical Sciences (UAMS) as section chief of Pediatric Pulmonary and Sleep Medicine.

Guimbellot, also an associate professor of Pulmonology at UAMS, now leads the U.S. News & World Report-ranked program providing infants and children with complete diagnosis and treatment of acute and chronic lung disease.

ACH is home to the only Cystic Fibrosis Center in the state of Arkansas reviewed and approved by the national Cystic Fibrosis Foundation. ACH’s Pediatric Pulmonary and Sleep Medicine program also offers a state-of-the-art pediatric sleep center and specialized clinics for asthma, chronic lung disease of infancy (BPD) and pulmonary complications of neurological and neuromuscular disorders.

“Dr. Guimbellot’s passion for patient care and dedication to bettering pulmonary specialty practice though her research makes her the right leader to guide this outstanding team,” said Rick Barr, M.D., executive vice president and chief clinical officer of Arkansas Children’s. “As we continue to build best-in-class hospital offerings and deliver the highest quality comprehensive care to the children of Arkansas and surrounding states, Dr. Guimbellot’s expertise will make a tremendous impact.”

Guimbellot holds a dual degree in Biochemistry and Molecular Biology from Mississippi State University, where she was a distinguished recipient of the Goldwater Scholarship. She holds a medical degree and PhD from the University of Alabama at Birmingham Heersink School of Medicine. There, she was a graduate of the NIH-funded Medical Scientist Training Program.

Prior to joining Arkansas Children's, Guimbellot conducted pediatric pulmonology research and clinical practice in numerous roles, with a focus on precision medicine and cystic fibrosis pharmacology. She was one of two inaugural Children’s of Alabama Scholar Awards for success in pediatric research in 2020, and served on the executive committee for the Section on Clinical Pharmacology and Therapeutics for the American Academy of Pediatrics.
