Collective cell migration and pattern formation are entwined phenomena of immense fascination. Development, tissue repair and disease progression all involve coordination between cell movements, growth, and intercellular signalling processes. A better understanding of their interplay across different spatial and temporal scales will help improve diagnosis and treatment of diseases. The aim of this workshop is to draw together state of the art techniques within (i) the biological mechanisms that underpin processes of collective cell migration and pattern formation, (ii) the mathematical and computational models used to study these phenomena, and (iii) the analytical tools that can be used to unlock core properties contained within these models.
