Han obtained his Bachelor of Medicine and Bachelor of Surgery (MBBS) degree from the University of Melbourne and completed his Cardiology training at the Austin Hospital, before undertaking subspecialty training in the area of cardiac electrophysiology and device implantations. He is a recipient of the NHMRC (National Health and Medical Research Council) Medical Postgraduate Scholarship for his PhD in the area of stroke prevention in atrial fibrillation (AF). For his overseas advanced cardiac electrophysiology fellowship, Han trained with Professor Michel Haissaguerre in Bordeaux, France, who pioneered the technique of catheter ablation for AF. Han has extensive experience in the area of catheter ablation for complex arrhythmias, including the latest ablation techniques for AF, supraventricular, tachycardia and ventricular tachycardia, as well as pacemaker and implantable cardioverter defibrillator implantations. Han holds public appointments at Austin Hospital and Northern Hospital. He is an Associate Professor at the University of Melbourne. His research interests are in the area of heart rhythm disorders, particularly atrial fibrillation and stroke, and sudden cardiac death.
