We use archival data from the Hubble Space Telescope to study the statistical changes in galaxy morphology with cosmic epoch and local projected density in nine clusters with 0.3 < z < 0.8. We estimate the morphological properties of every galaxy in our sample, quantitatively, using a full two dimensional bulge-disk decomposition. The large sample size requires the development of an automated, sophisticated pipeline to perform the decomposition. I will describe the data processing pipeline and discuss our measurements of the morphology density relation and the time evolution of morphology in cluster cores. Constraints on galaxy formation scenarios placed by our measurements will also be discussed.
