Sander Verheule

Associate professor

Dr Sander Verheule has studied Biology at the University of Utrecht, with internships at the Hubrecht Laboratory for Developmental Biology and at the Department of Neurophysiology (VU Amsterdam). As a PhD student in the group of Dr Habo Jongsma (Department of Medical Physiology, Utrecht), he investigated the distribution and electrophysiological behavior of gap junction channels in various regions of the heart, defending his PhD thesis in 1999. From 1999-2003, he worked as an AHA post-doctoral fellow in the group of Dr Jeffrey Olgin and Dr Douglas Zipes at the Krannert Institute of Cardiology in Indianapolis, Indiana. There, his research focussed on the impact of structural remodeling on atrial conduction.

In 2003, Dr Verheule joined the electrophysiology group at the Department of Physiology in Maastricht. In his current research, he investigates the pathophysiological mechanisms underlying atrial fibrillation, and the recognition of these mechanisms in patients. His two main research questions are 1) How do atrial vascular and metabolic remodeling contribute to the progression of atrial fibrillation? and 2) How do changes in atrial tissue structure affect atrial electrical propagation?
