Sandro Ninni after performing his training in the electrophysiology department of the University Hospital of Lille became an associate professor in the same institution. His research is more specifically focused on the field of atrial fibrillation with the development of the translational approach to better understand pathophysiological mechanisms involved in atrial remodeling. He has also developed research topics focusing on ventricular arrhythmias with a special focus placed on the management of electrical storms.
