Description
I describe the cosmic evolution of galaxy discs from z~6 to the present using bars as a sign post of galaxy evolution. I will describe the observations and analysis from two fundamental surveys I have led, namely COSMOS and S4G which together form the foundational datasets for the study of galactic structure from high redshifts to the local Universe. We find that galaxy disk assembly and maturity is a strong function of the galaxy mass and shapes clear signs of galaxy downsizing in the formation of structure. I will also describe the many outstanding questions in this area of research and what we need to do next in using the next generation of telescopes to solve these questions.
