Dr. Schwab has emerged as a preeminent investigator in the field of upper airway imaging and sleep apnea. He has developed and utilized sophisticated magnetic resonance imaging and volumetric analysis paradigms to study the mechanisms leading to sleep apnea. His research has resulted in seminal observations about the genetics, pathogenesis and treatment of obstructive sleep apnea. He has shown the importance of the lateral pharyngeal walls and tongue volume in the pathogenesis of sleep apnea. In addition, he has shown that reductions in tongue fat mediate the improvement in sleep apnea with weight loss. Finally. Dr. Schwab has successfully mentored a number of pulmonary/sleep fellows and started the ASPIRE fellowship which provides a pipeline for next group of pulmonary/sleep leaders.
