Dr. Abdelnaby Khalyfa is a professor in the Department of Biomedical Sciences, Joan C. Edwards School of Medicine, Marshall University, Huntington, WV, USA. He holds a PhD from McGill University, Montreal, QC, Canada, in 1993. Dr. Khalyfa has conducted groundbreaking research relating to obstructive sleep apnea in children, linking the disorder to genetic disruptions that lead to inflammation, organ dysfunction, and metabolic dysfunction. He was also the first researcher to link sleep disruption during pregnancy to metabolic dysfunction in offspring. Dr. Khalyfa was the first to study the role of exosomes in sleep apnea-related morbidities, including endothelial dysfunction, neurocognitive deficits, cancer, and metabolic disorders. His research interests mainly include exosomes, genetic markers, sleep apnea, snRNA-seq, metabolic dysfunction, and animal models for sleep apnea.
