Derek J. Dosdall, PhD, is an associate professor at the University of Utah in the Depatment of Surgery, Division of Cardiothoracic Surgery. He has adjunct appointments in the Department of Bioengineering and the Deparmtment of Internal Medicine, Division of Cardiovascular Medicine. He received his PhD in Bioengineering from Arizona State University and did postdoctoral training at the University of Alabama at Birmingham.
His research interests are focused on mapping of cardiac arrhythmias. He has developed chronic animal models of atrial fibrillation to investigate the substrate and conduction changes that occur in the cardiac tissue over time. He is working to determine the role of fibrosis in conduction disturbances and the development of atrial fibrillation. He is also studying the role of the specialized conduction system in the ventricles and the onset and maintenance of dangerous cardiac arrhythmias.
