Research Assistant and PhD Fellowship in Cardiovascular Digital Twins (F5) - Strand, London, WC2R 2LS

About Us

A 3-year PhD-fellowship is available at the School of Biomedical Engineering & Imaging Sciences at King's College London. This position is part of the Cardiovascular Digital Twin network consisting of 15 fellowships across Europe ( CDTnet ), funded by the European Research Councils MSCA programme.

As a world-leading, research-intensive university ranked among the global top 40, King's offers PhD candidates an exceptional academic environment co-located with clinical teams at St Thomas' Hospital, uniquely bridging the gap between research, medical imaging, and active patient care. Within this framework, our Digital Twins for Healthcare department pioneers precision medicine by engineering virtual patient replicas to predict and treat complex diseases.

About the role

Cardiovascular digital twins have the potential to transform medicine by providing personalised models of anatomy and physiology that support diagnosis, prognosis and treatment planning. However, creating these models currently requires complex and time-consuming workflows that limit their use in large patient populations and routine clinical practice.

This project aims to develop new methods for personalising cardiovascular digital twins at scale. The doctoral candidate will create computational approaches capable of estimating anatomical, mechanical and electrophysiological parameters from large imaging datasets while addressing the challenges of limited patient-specific data and uncertainty in model predictions. A key objective is to identify the appropriate balance between model complexity and clinical applicability, allowing robust digital twins to be generated efficiently for large numbers of individuals.

The project will make extensive use of the UK Biobank, one of the world's largest health research resources, with access to imaging and functional data from about 100,000 participants. Using these data, the candidate will develop population-based reference values for cardiac anatomy and function, including parameters such as contractility, passive stiffness and

electrical conduction properties. The project will also investigate how these parameters change over time by studying longitudinal data from thousands of participants and constructing digital twin trajectories that describe cardiovascular ageing and disease progression.

An important aspect of the research will be the study of variability across populations, including differences related to sex and ethnicity. The resulting methodologies and datasets will support many of the other CDTnet projects by providing population-scale digital twin frameworks that can be applied to heart failure, arrhythmias and valve disease. Ultimately, the project aims to help make personalised cardiovascular modelling more accessible, scalable and clinically useful.
