Dr. Ahmad is Director of the Genetics Laboratory at Al Jalila Children’s. He completed his doctoral studies (PhD) at Dartmouth College in the USA followed by a fellowship in molecular diagnostics at Dartmouth Medical School. In 2013, he joined Harvard Medical School where he completed his clinical molecular genetics fellowship and, in 2015, became board-certified by the American Board of Medical Genetics and Genomics (ABMGG). Dr. Abou Tayoun is a fellow of the American College of Medical Genetics and Genomics.

Prior to joining Al Jalila Children’s, he was a director in the Division of Genomic Diagnostics at the Children’s Hospital of Philadelphia, and also an assistant professor of Pathology and Laboratory Medicine at the University of Pennsylvania Perelman School of Medicine. To support clinicians in various specialties at CHOP, Dr. Ahmad developed genomic sequencing-based diagnostic tests for a range of pediatric disorders. He also developed and published several tools and assays involving next generation sequencing and variant interpretation. Dr. Abou Tayoun is a co-chair of the Clinical Genome Resource (ClinGen) Hearing Loss Expert Group, and is a member of the ClinGen Sequence Variant Interpretation group. In both capacities, Dr. Abou Tayoun is working with international experts to establish guidelines and recommendations for sequence variant interpretation in general, and in the hearing loss disease area specifically.
