My research areas of interest include improving the safety and efficacy of complex ablation and optimal use of pacemakers in patients with heart failure, including cardiac resynchronization therapy and conduction system pacing. I am also interested in non-pharmacologic management of atrial fibrillation, including catheter ablation and left atrial appendage occlusion, and understanding optimal use of novel and emerging technologies.
