Hythem Nawaytou, MD
Associate Professor
Pediatrics
School of Medicine

Nawaytou's research focuses on ways to better diagnose children with pulmonary hypertension and follow their progress over time. He also studies the use of echocardiography to evaluate heart function.

Nawaytou earned combined bachelor of medicine and bachelor of surgery degrees at Cairo University's Kasr Alainy Faculty of Medicine. He completed a residency in pediatrics at State University of New York Downstate Health Sciences University, followed by a fellowship in pediatric cardiology at UCSF and a fellowship in advanced cardiac imaging at Children's Hospital of Philadelphia.

In his free time, Nawaytou enjoys painting.
