Undergraduate Research, Clustering Properties of Faint Galaxies: As part of my "Licenciatura" thesis I studied the two-point angular correlation function, at small angular scales. This has been extensively used to study the clustering properties of galaxies. I showed that at small angular separations there is an excess of clustering over what would be expected from an extrapolation of it value measured at larger scales. The study suggested clustering evolution at larger angular scales as well as a clear detection of the scale where clustering evolution approaches a highly non-linear regime. Cambridge Research, Formation and evolution of spheroidal galaxies: The question is whether elliptical galaxies formed the bulk of their star in at high redshift as viewed by "traditional" models, or formed over longer period from the subsequent merging of low mass disks as predicted by CDM models was the central line of research for PhD thesis. I used HST images and near-IR observations I studied the optical near-infrared colours of field spheroidals. I learnt that no constant co-moving density traditional model succeeds in reproducing the bulk properties of ellipticals. Subsequently I studied the internal properties of high-z spheroidal in the Hubble Deep Fields North and South, where I detected a large fraction of spheroidals at high-z with blue central cores, a strong evidence for the case of continuous formation of ellipticals. Today my work still focuses on the formation and evolution of elliptical galaxies, trough observational programs and modelling of the spectral properties of field ellipticals which will allow us to understands the formation time-scales and some of the mechanism involved. I concentrate most of my time using the new ACS data to resolve galaxies at high redshift both in the field and in the cluster. Trying to make sense of how the new window of the spatial information can help us in the study of galaxy evolution. In case you
