/ Abstract

We have used the Advanced Camera for Surveys (ACS) on the HST to obtain optical imaging of a sample of 8 galaxy clusters in the redshift range 0.8 2. We will also present results from our study of the evolution of the Morphology-Density relation in clusters since z~1 down to the present day universe. Our cluster evolution studies are also being complemented by observations of protoclusters at redshift z>~2.
