Dr. Esther Pueyo received her M.S. degree in Mathematics from the University of Zaragoza, Spain, in 1999. In 2000, she was a research student at the Department of Mathematics, University of Zaragoza, where she developed a minor thesis in the field of Calculus. In 2001, she started her Ph.D studies in Biomedical Engineering at the University of Zaragoza, aimed at developing signal processing techniques applied to the electrocardiogram with the purpose of investigating conditions predisposing to arrhythmogenesis. During that time, she also worked as an Assistant Professor of Signal Processing at the Department of Electronic Engineering and Communications and she was a visiting scholar at research centers in Portugal, Argentina, and the UK, with long research visits at St. George’s Hospital Medical School, London, UK. Next, she moved to the University of Oxford, UK (2007–2009) to receive postdoctoral training in computational modeling and simulation of cardiac electrophysiology. In January 2011, she was appointed Associate Professor at the University of Zaragoza, Spain. Currently, she is Full Professor. Her research aims at shedding light on the mechanisms and manifestations of cardiac arrhythmias at scales ranging from cellular ion channels to the electrocardiogram and on the role of important modulators such as the Autonomic Nervous System.
