Scientific expertise:

The CARE group is currently focused on the following five major projects:

  1. Tissue engineering: This work focuses on the development of decellularised valvular scaffolds, which can either implanted without cells, or can be seeded with autologous cells and conditioned in a bioreactor, in order to develop valve-equivalent functionality prior to implantation. The work is also focused on developing methodologies for the 3D printing of scaffolds for tissue engineering.

  2. Biohybrid devices: This project focuses in the development of bioactive coatings and methods for tethering endothelial cell attachment on the artificial blood-contacting surfaces of extracorporeal membrane oxygenators and ventricular assist devices (VADs). Consolidating these technologies, the work also focuses on the development of a fully implantable biohybrid intracorporeal membrane oxygenator (iCMO).

  3. Implant infection: The work in this project is focused on developing solutions for inducing antimicrobial resistance to cardiovascular implants.

  4. Patient-specific computational modelling: This project is focused on fluid-solid-interaction (FSI) computational models of the heart using patient-specific anatomies, with a view to developing a prognostic virtual platform that will enable cardiac surgeons to make patient-specific pre-operative decisions by optimising valve replacement and repair, and VAD implantation. This work also focuses in developing disease-specific models for assessing oxygenator function and operation.

  5. Near-physiological in vitro testing: This work is focused on developing in vitro near-physiological methodologies for assessing the biomechanical and haemodynamic function of cardiovascular and pulmonary implants, aiming to reduce, refine and replace (3Rs) animal testing.
