Dr Atul Verma is the director of cardiology for the McGill University Health Centre and McGill University and is also the Isadore Rosenfeld Chair in Cardiology. He is a full Professor of Medicine. He is an electrophysiologist with an interest in complex ablation, particularly for AF and VT; new technologies; and clinical trials. He has over 300 peer-reviewed publications including in the New England Journal of Medicine, JAMA and the Lancet. He is currently an international expert in pulsed field ablation and other novel technologies for cardiac ablation. He has also served as Chair or on the Writing Committee of both national and international guidelines for AF.

Dr Nick Jackson studied cardiology and electrophysiology at John Hunter Hospital in Newcastle and at Toronto General Hospital in Canada. He is now a conjoint senior lecturer with the University of Newcastle and a staff specialist at John Hunter Hospital. During this time he has authored over forty peer reviewed articles and book chapters, including work on ventricular fibrillation in explanted human hearts and new mapping techniques for ventricular tachycardia ablation.

A/Prof Han Lim is a cardiac electrophysiologist at Austin and Northern Health in Melbourne, and the University of Melbourne. His PhD was in the area of stroke and atrial fibrillation (AF) with Professor Prashanthan Sanders. His postdoctoral research was undertaken in Bordeaux, France, with Professor Michel Haissaguerre. Han leads the EP service and research program at Austin Health, University of Melbourne, with a special interest in sudden cardiac death and atrial fibrillation. He has co-authored 120 peer reviewed publications in leading Cardiology journals and 6 book chapters. Previous awards include the Parmley Prize from the American College of Cardiology and Samuel Levine Young Investigator Award Finalist by the American Heart Association.

A/Prof Kumar is a cardiologist and electrophysiologist, program director for ventricular arrhythmias and sudden death at Westmead Hospital and Associate Professor of Medicine at the University of Sydney. His research interests include genetic basis of ventricular arrhythmias, in particular channelopathies and cardiomyopathies.

A/Prof. Haris Haqqani is a Senior Consultant Cardiologist & Electrophysiologist at the Prince Charles Hospital. He was trained at the University of Melbourne, Royal Melbourne Hospital and the University of Pennsylvania. His research has focused on the mechanisms of VT in heart failure. Haris has authored or co-authored more than 100 journal papers, 20 book chapters and several national and global arrhythmia guidelines and is a regularly invited conference speaker.

Prof. Dr. Natasja de Groot, cardiologist-electrophysiologist is appointed at Erasmus University Medical Center and Delft University of Technology. She is chief of the research unit Translational Electrophysiology, Department of Cardiology. Her research focuses on unravelling the electrical mechanism of cardiac arrhythmias, particularly arrhythmias in (pediatric) patients with congenital heart disease and (post-operative) atrial fibrillation. For this purpose, she has developed unique signal recording and processing technologies. With insights obtained from these technologies, she develops, tests and implements novel diagnostic instruments and therapies. She is a Fellow of the EHRA, co-chair of EHRA 2025 and is involved in writing various international guidelines of the European Society of Cardiology, European Heart Rhythm Association and Heart Rhythm Society. In her clinical work, she focuses on ablation therapy of patients with congenital heart disease and atrial tachyarrhythmias.
