Our research is centred on highly porous “fibre network materials” (bonded assemblies of fibres) and open-cell scaffolds. Fibre network materials have the potential for actuation in vivo, since they can exhibit controlled reversible shape changes. A central feature of our research is the study of the various inter-relationships between architecture, mechanical properties, and cell responses. Architecture is most effectively quantified by computed X-ray tomography and such data can be used in conjunction with models for property prediction.
Controlling mass transport and building a fully functional vasculature are vital for producing tissue in clinically relevant dimensions. To address these, the group is working on 3D printing, and the design of bioreactors using open-source technologies.
