Biographic Notes
I am a FCT Fellow whose main research topic is the understanding of the most massive galaxies at all redshifts. These "monsters" were already formed at very large cosmic distances (> 12 Gyr!), being extremely compact disk-like galaxies and some of them "dead and dead" at this very early stage in the life of the Universe. My aim is to characterise how they transformed to the huge elliptical galaxies we see in the nearby Universe, while at the same time looking for new Physics in this metamorphosis.
