Ronald Clyman

Dr. Ronald Clyman is a neonatologist and an expert in the treatment of extremely premature infants. He is internationally renowned for his basic and clinical studies of the ductus arteriousus, a blood vessel that transports blood from the right side of the heart to the aorta, which is the large blood vessel that distributes blood to a baby's body while still in the womb. He has helped define the role of oxygen and prostaglandins in ductus patency and is currently studying the mechanisms leading to irreversible ductal closure. Clyman is a professor of pediatrics at the University of California, San Francisco and a member of the Cardiovascular Research Institute. He earned his medical degree at Columbia University and is board certified in pediatrics and neonatal and perinatal medicine.
