Over the course of the last decade we have begun to put together a framework of how galaxies evolve with redshift or lookback time. We find that the gloal star formation density increases by a factor ten from the current day to redshifts z>1. This redshift also appears to correspond to the time at which the classical morphologies of galaxies first began to appear {i.e. at redshifts z>2 galaxies appear amorphous while at z=1 spiral galaxies are clearly present}. If we can study galaxies at these redshifts we might expect to gain insight in to the galaxy formation process. The goals of this proposal are, therefore, {1} to measure how star formation is distributed throughout a galaxy and how this evolves with redshift and environment, {2} to measure the morphologies of intermediate and high redshift galaxies in their restframe u and g bands and to compare these to local surveys and {3} to relate the star formation and morphological properties of galaxies to the physical processes that drive their evolution by comparing local and high redshift galaxies that occupy similar environments.
