Development of cardiomyopathy in at risk populations, including Duchenne muscular dystrophy and other genetic cardiomyopathies, and anthracycline exposure.

Thomas D Ryan, MD, PhD, was born and raised in Wichita, KS and graduated magna cum laude from Wichita State University in 1996 with a BS in biological sciences.

In 1997 he began training in the MD/PhD program at the University of Alabama at Birmingham, and studied the molecular, cellular, and whole organ aspects of cardiac remodeling in a rat model of volume overload. His general pediatrics residency training took place at Cincinnati Children’s Hospital Medical Center from 2006-2009, as did his pediatric cardiology fellowship training from 2009-2012 and advanced fellowship in Pediatric Heart Failure/Transplant from 2012-2013. His clinical and research interests focus on heart failure, cardiomyopathy, cardiac transplantation, and mechanical circulatory support.
