Dr. Quinn’s research focuses on feedback between cardiac mechanics and electrophysiology. The goals of his research program are to investigate mechano-sensitive mechanisms at the organ, tissue, cell, and subcellular levels; discover their relevance for heart rhythm in health and disease; and use this knowledge to develop novel targeted anti-arrhythmic therapies.
