My area of excellence at BWH and HMS is in clinical expertise and innovation, with a focus on genomics/phenomics of cardiac pathologies such as atrial fibrillation. I have a clinical practice in the Cardiac Electrophysiology Section of the Division of Cardiovascular Medicine, and I direct the Inherited Arrhythmias and Left Atrial Appendage Occlusion Programs. I also now serve as the interim director of the Cardiac Device Program.
