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.
Dr Angela WC Lee received her PhD in Biomedical Engineering from the University of Auckland, New Zealand. Her main research interest is in modelling cardiac resynchronization therapy using patient-specific models of the heart. Previously, her work focused on modelling the chronic changes in the heart’s electrophysiology, mechanics and geometry due to cardiac resynchronisation therapy and the effect that these changes will have on the optimal lead location. The current focus of her work is on developing a product for image-guided optimisation of wireless endocardial pacemakers for patients undergoing cardiac resynchronization therapy. This project, in collaboration with medical imaging companies, device manufacturers, and clinicians, aims to translate image-analysis and advanced simulations tools into the clinic to assist in pre-procedural planning for wireless endocardial CRT.
Dr Alex Lewalle completed his PhD in physics at Cambridge, and subsequently refocussed his research toward the physics/biology interface. His general research interest is in the mechanisms of force generation in biological systems, from the molecular to the whole-organ scale. His earlier research, combining experimental and modelling approaches, has included measurements of the myosin motor protein that produces muscle contraction, and of red-blood-cell membrane deformation. He has also modelled the dynamics of actin filament growth, the mechanical driving force in cell motility. Since joining CEMRG, he has focused on understanding, through modelling and computational simulations, the roles played by electrophysiological activity and cardiac tissue structure in heart contraction. By comparing theoretical biophysical models with clinical data, he is presently investigating the mechanisms of chemotherapy-induced heart failure.

He then expanded and refined these techniques while working at Clyde Biosciences while looking to determine the mechanisms of variation between populations of stem cell derived heart cells. He subsequently joined CEMRG, where he has developed interest in whole torso computational modelling, with specific focus on the effect of scar on the electrical dynamics of the heart, and how subtle changes in the clinical observations can be used to determine properties of myocardial scar prior to imaging.

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 project is 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 is 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.
