Dr. Joshua Moss is a cardiologist who specializes in diagnosing and treating complex heart rhythm disturbances, or arrhythmias. He has expertise in treating ventricular tachycardia, supraventricular arrhythmias, and atrial fibrillation using catheter ablation, in which the heart is accessed by passing a thin, flexible tube (catheter) through a blood vessel, and small areas causing the problem are cauterized. He is also skilled in surgically implanting pacemakers and defibrillators.

Moss is involved in multiple studies of existing and evolving techniques for treating patients with arrhythmias who have a left ventricular assist device (LVAD), a mechanism implanted in the chest to help the heart pump blood to the body. Drawing on his training as an engineer before medical school, he takes an active interest in designing and testing novel devices for managing heart rhythm disorders.

Moss has a master's degree in mechanical engineering from the Massachusetts Institute of Technology. After earning his medical degree at Harvard Medical School, he completed a residency in internal medicine at Massachusetts General Hospital. He then undertook advanced fellowship training in cardiovascular disease and cardiac electrophysiology at the University of Pennsylvania.

Outside of work, Moss enjoys spending time with his children, especially taking them to visit state and national parks. A licensed pilot, he also enjoys exploring California from the air.
