Star Formation in Galaxy Clusters Over the Past 10 Billion Years

Understanding how galaxies form and evolve in clusters continues to be a fundamental question in astronomy. The ages and assembly histories of galaxies in rich clusters test both stellar population models and hierarchical formation scenarios. Is star formation in cluster galaxies simply accelerated relative to their field counterparts, or do cluster galaxies assemble their stars in a fundamentally different manner? To answer this question, I review results at 0 < z < 1 from our Spitzer/MIPS Infra-Red Cluster Survey (SMIRCS) and present first results from one of the highest redshift cluster yet detected at z=1.62.
