Arnold W. Strauss, MD Associate Director for External Relations and Strategic Projects, Cincinnati Children's Research Foundation
Associate Director for External Relations and Strategic Projects, Cincinnati Children's Research Foundation
Arnold Strauss, MD, joined Cincinnati Children's in April, 2007, as chairman of the Department of Pediatrics at the UC College of Medicine, chief medical officer of Cincinnati Children's and director of the Cincinnati Children's Research Foundation. He is the seventh B.K. Rachford Memorial Chair in Pediatrics.
Dr. Strauss is a distinguished pediatric cardiologist, scientist, educator and leader. Prior to his arrival at Cincinnati Children's, he was the chairman of the Department of Pediatrics at the Vanderbilt University School of Medicine and medical director of the Monroe Carell Jr. Children's Hospital at Vanderbilt, a position he held from 2000 to 2007. Under his leadership, the university built and opened a new hospital for children, expanded its pediatric faculty and increased grant funding for pediatric research. From 1981 to 2000, Strauss was director of the Division of Pediatric Cardiology at Washington University/St. Louis Children's Hospital.
A respected scientist, Dr. Strauss' research focuses on understanding the molecular basis of disorders of mitochondrial fatty acid oxidation and the genetic causes of congenital heart disease and cardiomyopathies. He is the recipient of two of the most prestigious awards in research. In November 2006 he was awarded the American Heart Association's Basic Science Research Award for groundbreaking work that led to finding genetic defects that can cause heart failure and sudden death in infants and children. In 1991 he received the E. Mead Johnson Award for Excellence in Pediatric Research.
