Biomedical Engineering

We build patient-specific computational models that bridge engineering mechanics and clinical medicine. Our goal is to understand how geometry, material properties, and blood flow interact to drive disease progression — and to support clinical decision-making with in-silico tools.


Cardiovascular Biomechanics

We build patient-specific computational models of the cardiovascular system to understand how geometry, wall mechanics, and blood flow interact to drive disease progression. Our work spans two key areas: aortic aneurysm rupture risk and carotid haemodynamics.

For abdominal aortic aneurysms (AAA), we develop virtual patient populations to re-assess rupture risk using detailed neck geometry, going beyond the simple diameter-based criteria currently used in clinics. For carotid haemodynamics, we use in silico modelling to analyse how carotid geometry and flow conditions influence plaque formation and atherosclerosis risk.

  • Patient-specific finite element models of aortic wall mechanics
  • Virtual populations for statistical AAA risk assessment
  • Influence of neck geometry on haemodynamic loading
  • Computational fluid dynamics of carotid bifurcation flow
  • Wall shear stress distributions and oscillatory indices
  • Patient-specific geometry from medical imaging

Retinal Biomechanics

The eye presents unique biomechanical challenges — small dimensions, large deformations, and complex fluid-tissue interactions. We apply computational methods to retinal imaging analysis and ocular biomechanics to understand disease mechanisms and improve diagnostic tools.

  • Scaling effects in retinal fundus image analysis
  • Axial length and its influence on image interpretation
  • Finite element modelling of ocular tissue mechanics

Soft Tissue Mechanics

Tendons and soft connective tissues are highly anisotropic, viscoelastic structures subject to large deformations under physiological loading. We develop high-fidelity finite element models using the Absolute Nodal Coordinate Formulation (ANCF) to capture fibre-level constitutive behaviour, contact, and damage in soft tissue.

  • ANCF-based models for large-deformation tendon and soft tissue mechanics
  • Fibre-reinforced constitutive models for soft connective tissue
  • Damage and failure mechanics under cyclic loading
  • Multi-scale modelling from fibril to tissue level
  • Contact mechanics in beam and continuum elements
