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 and interventional procedures in Cardiology:

  • 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)
