A major problem of contemporary cosmology is to understand how galaxies form and evolve, due to the complexity of the processes involved. The study of galaxy evolution in clusters is particularly interesting due to the extreme conditions found in these structures. We propose to address the problem of how galaxies evolve in the redshift interval between z~0.5 and 1 through spectroscopic and photometric analysis of galaxies in a well defined sample of galaxy clusters by making use of spectral synthesis techniques. This approach should allow us to determine the evolution of important parameters characterizing the stellar populations of cluster galaxies, such as the stellar mass and the mean stellar ages and metallicities.
