Dr. Williams was a pioneer in the field of echocardiography, beginning in 1973. She developed the initial clinical correlations with echo findings that formed the bases of non-invasive diagnosis of a wide variety of cardiac anomalies. She established the accuracy of diagnosis that allowed echo to supplant cardiac catheterization prior to surgical correction for many types of defects. These observations changed management of congenital heart disease around the world. She was one of the few world-wide leaders who advanced the development of Doppler and fetal echocardiography. More recently, her research interests have focused on clinical outcomes of medical and surgical management of congenital heart disease, and physician workforce needs and lifetime healthcare for patients with chronic childhood diseases.
