Dr Hector Martinez-Navarro

Junior Research Fellow

Senior Postdoctoral Researcher

Department of Computer Science

My name is Hector Martinez-Navarro, and I come from Valencia, Spain. My background is multidisciplinary, including a BSc and MSc in Computer Science, and a second MSc in Human Physiology. In 2019 I obtained my DPhil degree at Oxford in the Computational Cardiovascular Science (CCS) group, at the Department of Computer Science. In the following years, I held a Postdoctoral Fellow position at the Oslo University Hospital and finally, in October 2022, I returned to the CCS group as a Senior Postdoctoral Research Associate, funded by the Wellcome Trust. Currently, I supervise my first doctoral student, and I have demonstrated in several courses at the Doctoral Training Centre at the University over the past few years. My experience in tutoring is very extensive, and I enjoy research dissemination and outreach activities.

My current research focuses on exploiting computer simulations of cardiac electrophysiology to investigate the dynamics of cardiac arrhythmias and their potential relevance to clinical intervention. This project is conducted in alliance with Zoll Medical Corporation, a medical company centred on the development of cardiac resuscitation devices. In more detail, I will investigate how the metabolic alterations arising during ventricular fibrillation may change the electrical properties of the tissue and hence modulate the electrocardiographic signal, critically relevant in the management of these patients. However, the outcome of this project is not limited to providing mechanistic insights into the formation of arrhythmias; it is an essential aspect of this research to produce knowledge on how to improve the use of electrocardiographic data during resuscitation protocols, given that optimal timing of defibrillation shocks correlates with higher survival rates.
