We discuss the state of the assembly of the Hubble Sequence in the mix ofbright galaxies at redshift 1.4< z \le 2.5 with a large sample of 1,671galaxies down to H_{AB}~26, selected from the HST/ACS and WFC3 images of theGOODS--South field obtained as part of the GOODS and CANDELS observations. Weinvestigate the relationship between the star formation properties andmorphology using various parametric diagnostics, such as the Sersic lightprofile, Gini (G), M_{20}, Concentration (C), Asymmetry (A) and multiplicityparameters. Our sample clearly separates into massive, red and passive galaxiesversus less massive, blue and star forming ones, and this dichotomy correlatesvery well with the galaxies' morphological properties. Star--forming galaxiesshow a broad variety of morphological features, including clumpy structures andbulges mixed with faint low surface brightness features, generallycharacterized by disky-type light profiles. Passively evolving galaxies, on theother hand, very often have compact light distribution and morphology typicalof today's spheroidal systems. We also find that artificially redshifted localgalaxies have a similar distribution with z~2galaxies in a G-M_{20} plane.Visual inspection between the rest-frame optical and UV images show that thereis a generally weak morphological k-correction for galaxies at z~2, but thecomparison with non-parametric measures show that galaxies in the rest-frame UVare somewhat clumpier than rest-frame optical. Similar general trends areobserved in the local universe among massive galaxies, suggesting that thebackbone of the Hubble sequence was already in place at z~2.
