Galaxy morphology is one of the basic observables that can be used to trace the evolution of galaxies, and constrain theories of galaxy formation. The high resolution images from HST have proved to be extremely valuable for performing quantitative morphological classifications of distant galaxies. The Great Observatories Origins Deep Survey (GOODS) HST treasury program has used the Advanced Camera for Surveys (ACS) to produce deep, multiband images over two fields covering a total area of 320 arcmin2. The images have been obtained using the F435W, F606W, F775W, and F850lp filters, and allows to explore the restframe optical properties of galaxies out to z ˜ 1. The high spatial resolution and high sensitivity of the ACS has resulted in images which allows to study galaxy structure in unprecedented detail at high redshifts. In this talk, I will provide an overview of the various analysis being done by the GOODS team to study the morphological evolution of galaxies. I will focus primarily on the evolution of the structural parameters derived from the surface brightness profiles, and the concentration and asymmetry indices with redshift.
