After graduating in medicine in 1996, she went on to specialize in cardiac electrophysiology and started off with research on the electrophysiological properties of the pulmonary veins in large animal models and in patients. She has been strongly implicated in the development and evaluation of several innovative therapeutic strategies in atrial fibrillation. Some discoveries led to the development of a curative treatment recommended by international guidelines currently benefiting several hundreds of thousands of patients every year worldwide. She has also a keen interest in lethal ventricular arrhythmias, particularly ventricular fibrillation in different patient populations (IVF, J wave syndromes, ischemic VF, and VF in the setting of hypertrophic cardiomyopathy). She is currently leading the first large-scale study on the characterization of human VF dynamics in various patient populations to better understand VF mechanisms and to propose solutions to detect and prevent patients at risk of SCD.
