Enhanced organ/system models

Clinically representative test beds – whether in vitro, ex vivo and in silico are of paramount importance for advancing therapetuic technologies along the translational bath to becoming approved medical devices. We develop advanced, dynamic in vitro test-beds and simulators that recreate three-dimensional motion, hemodynamics and tissue properties simultaneously. We also use computational tools such as finite element analysis to model performance of devices, optimize device design, and reveal the effect that devices have on the constitutive properties, dynamics and function of the receiving tissue and environment.
