My research programme spans from basic aspects of myocardial redox signalling (e.g., Carnicer et al. Circ Res 2021; Simon et al Circulation 2021) to patient-based investigations and clinical trials with a focus on atrial fibrillation and heart failure. Examples of the scope and range of our on-going work include the investigation of myocardial mechanisms promoting the maintenance of atrial fibrillation in humans (Reilly et al. Science Transl Med 2016; Moreira et al. Nature 2020) and the impact of perioperative statin therapy on the new onset of atrial fibrillation after cardiac surgery and other postoperative complications (Zheng et al. New Engl Med J 2016).
