This colloquium will serve as a forum for an up-to-date account of the recent advances in testing approaches, imaging techniques and inverse problems for applications in tissue mechanics and biomechanics. The colloquium will be the occasion of gathering the main European leading actors involved in developing advanced tools for characterizing the mechanical behaviour of biotissues and in applying these tools to actual clinical situations. The colloquium is intended to be interdisciplinary and open to authors working in different fields but that may have a common interest in inverse methodologies and optical techniques for biomechanics and tissue engineering.
