Paul Iaizzo
University of Minnesota

Paul A. Iaizzo, PhD FHRS ([email protected]) is a Professor is the Departments of Surgery, Integrative Biology & Physiology and the Carlson School of Management, at the University of Minnesota. He also serves on the graduate faculties in Biomedical Engineering, Neuroscience, Integrative Biology & Physiology, Biological Science, Bioinformatics and Computational Biology and Mechanical Engineering. He is the Director of the Malignant Hyperthermia Diagnostic Center and Medtronic Professor of Visible Heart® Research. Additionally, he is the Associate Director and Medtronic Chair of the Institute for Engineering in Medicine, also at the University of Minnesota. He earned both MS and PhD degrees (Focus: Physiology/Neurophysiology) from the University of Minnesota. His main research focus is translational systems physiology, where his research group does a broad range of studies. The Visible Heart® Laboratories are well known for their multimodal imaging techniques of functional cardiac anatomies and device testing within large mammalian hearts, including human: see the Atlas of Human Cardiac Anatomy ( Other research areas include: cardiac pacing and ablation, muscle pathophysiology and biophysical properties, thermoregulation, black bear hibernation, 3D computational modeling and printing and educational uses of virtual reality. In 2002, he was acknowledged as a “Distinguished University Teaching Professor”. Since 1990, he has trained over 200 graduate students, postdoctoral fellows, and medical students in his laboratories. Dr. Iaizzo, has authored more than 280 original articles, over 100 book chapters, edited 5 books, and is on numerous patents related to medical devices. In 2012, he was named to College of Fellows of the American Institute for Medical and Biological Engineering (AIMBE) for "outstanding contributions to research and education in translational systems physiology and cardiovascular engineering". In 2015 he was named a Fellow of the Heart Rhythm Society and in 2016 was made a Senior Fellow of IEEE.
