This Doctor of Philosophy Dissertation in Matematica per le Scienze dell’Ingegneria is composed by two distinct parts having in common the study of the interactions between cells and extracellular-matrix. This is the result of a three year working project supervised by professors Davide Ambrosi (Politecnico di Milano) and Luigi Preziosi (Po- litecnico di Torino). In the spirit of the aims and scopes of the Doctoral degree, both modelling and applications of analytical/numerical methods constitute the backbone of such a work; in fact, the first part emphasizes the latter aspect whilst the second part is more focused on the former. Specifically: 1. Part I deals with the mathematical aspects of Force Traction Microscopy. This is an inversion method that allows to reconstruct the stress field acting on a substratum knowing the displacement of the substrate itself, measured at some points. The formulation of this problem in the Inverse/Optimal Control framework together with its analytical and numerical study constitutes the real aim of this part of dissertation. Remarkably, some contents of this part had been submitted [70]. 2. Part II deals with the mathematical modeling of cell-tissue adhesion. Such an adhesive property of living tissue seems to be of importance in the developing of biological process. Moreover, quite a huge amount of experimental data can be found in the specialistic literature. A Continuum Mechanics point of view is adopted to describe adhesion and the outcome of our model is qualitatively compared with experiments. Remarkably, some contents of this part had been published [59].

Abstract
This Doctor of Philosophy Dissertation in Matematica per le Scienze dell’Ingegneria is composed by two distinct parts having in common the study of the interactions between cells and extracellular-matrix. This is the result of a three year working project supervised by professors Davide Ambrosi (Politecnico di Milano) and Luigi Preziosi (Po- litecnico di Torino). In the spirit of the aims and scopes of the Doctoral degree, both modelling and applications of analytical/numerical methods constitute the backbone of such a work; in fact, the first part emphasizes the latter aspect whilst the second part is more focused on the former. Specifically: 1. Part I deals with the mathematical aspects of Force Traction Microscopy. This is an inversion method that allows to reconstruct the stress field acting on a substratum knowing the displacement of the substrate itself, measured at some points. The formulation of this problem in the Inverse/Optimal Control framework together with its analytical and numerical study constitutes the real aim of this part of dissertation. Remarkably, some contents of this part had been submitted [70]. 2. Part II deals with the mathematical modeling of cell-tissue adhesion. Such an adhesive property of living tissue seems to be of importance in the developing of biological process. Moreover, quite a huge amount of experimental data can be found in the specialistic literature. A Continuum Mechanics point of view is adopted to describe adhesion and the outcome of our model is qualitatively compared with experiments.
