Dr. Abdenur is the chief of the division of metabolic disorders at CHOC Children's and Director of CHOC's metabolic laboratory one of only a few such laboratories in the United States. He is board certified in clinical biochemical genetics and is a member of the guidelines committee for the Newborn Screening Program, Genetic Diseases Screening Program for the California Department of Health.
Dr. Abdenur completed fellowship training in pediatric endocrinology, metabolism and nutrition at North Shore University Hospital, Cornell University Medical College. He also completed fellowship training in Biochemical Genetics, at the Denver Children's Hospital and The Biochemical Genetics Laboratory at the University of Colorado Health Sciences Center, and in Clinical Genetics at Mount Sinai School of Medicine in New York. Dr. Abdenur completed his pediatric residency training at Hospital General de Ninos Dr. Pedro de Elizalde in Buenos Aires and received his medical training at the Universidad de Buenos Aires, Argentina.
Dr. Abdenur is dedicated to investigating screenings for metabolic disorders in newborns and dietary treatments for newborns with fatty acid oxidation defects. He is currently working on newborn screenings for Krabbe disease. He is also working to identify maternal metabolic disorders through a newborn screening program. In addition, he is investigating the use of low-fat diets for infants with Mead deficiency.
Dr. Abdenur has coauthored more than 150 abstracts, presentations, book chapters, and journal articles and has received numerous awards.
