I am a professor at the department of Astronomy at the University of Maryland, College Park since 2005. My main scientific interests are in cosmology, theoretical and computational astrophysics. My research focuses on the cosmic epoch when galaxies, stars and black holes first appeared in the Universe. Prior to coming to Maryland I spent time at the IoA in Cambridge, UK (for a postdoc: 2002-2004), the University of Colorado in Boulder (for my PhD: 1997-2002), and Arcetri in Florence (my hometown), Italy where I obtained my Laurea in Physics (BS/MS).
