I am an observational astronomer and my research focuses on the formation and evolution of galaxies. My experience includes deep imaging and spectroscopic surveys, both from space (HST) and the ground, mostly at UV/Optical/Near-IR wavelengths. My observations aim to identify galaxies at the time of their formation, explore the dispersion of their their properties and follow their evolution to the present cosmic times with the goal of informing cosmological theories. Currently, I am trying to understand the physics behind the evolution of the star formation activity in galaxies, from its onset to the quenching, and why galaxies appear to transform their structures, from disks to spheroids, as they evolve.
