I am currently part-time research assistant at the Department of Cardiology, Medical University of Graz, Graz Austria. My research covers three main topics, evaluating different aspects of atrial fibrillation:

  • Pathophysiology of atrial fibrillation (preclinical studies)
  • Atrial fibrillation and cardiac procedures (especially transcatheter aortic valve implantation)
  • Treatment of atrial fibrillation (cardiac ablation, left atrial appendage closure)
