Following his undergraduate degree in Physics (University of Oxford, UK), Martin Bishop studied for a PhD in Computational Biology (University of Oxford, UK), specialising in Computational Cardiac Modelling, with a PhD project concerned with simulating the fluorescent signals obtained from optical mapping recordings of cardiac electrophysiology. In his first postdoc, Martin developed fine-scaled computational cardiac models directly from high-resolution MRI data, which were used in his later 4-year Sir Henry Wellcome Postdoctoral Fellowship to investigate the role of anatomical heterogeneity in the mechanisms of initiation and maintenance of arrhythmias.
Following his Fellowship, Martin took-up an academic position at King’s College London in the Department of Biomedical Engineering, where he is now a Reader in Computational Cardiac Electrophysiology. His core focus is to understand arrhythmia and electrotherapy mechanisms in different types of structural heart disease to directly improve clinical practice via enhanced arrhythmic risk stratification, and optimising implanted device therapy and catheter ablation. Martin’s work is facilitated by the use of clinical imaging data and electrophysiology recordings for both model construction and validation, including direct interaction with medical device and mapping companies, and basic science experimentalists. His current research interests involve the integration of computational models with advanced machine learning approaches to facilitate the integration of modelling into direct clinical practice.

Hassan graduated as an applied mathematician from The University of Nottingham, going on to complete an MSc in Applied Statistics with Operational Research and a PGCE in mathematics. His background has seen him work in various fields: Nottinghamshire police, teaching, research, start-ups and the NHS.
Hassan’s PhD project was based on the understanding that susceptibility to cardiac arrhythmias represents a highly complex system with intrinsic dependence on pathological structural and functional cardiac properties. Current guidelines suggest the use of a compromised LV ejection fraction (LVEF) to guide ICD implantation; however, only a third of SCD cases exhibit low LVEF. Functional biomarkers (from ECG recordings) and structural biomarkers (from MR imaging) have been independently correlated with arrhythmia risk, however, they have yet to demonstrate sufficient power to alter current clinical practice. Therefore, Hassan’s hypothesis was that a risk prediction model which combines both structural and functional features, augmented by structure-function simulation-based features, will significantly enhance risk stratification for ICD requirement. He completed his PhD on February 2024.
