Marco Bondi (b. 1963) works at the Istituto Nazionale di Astrofisica in Bologna, where his research activity is mainly focused on radio studies of active galactic nuclei and star-forming galaxies. His multiwavelength surveys are aimed at investigating the properties and cosmological evolution of the sub-millijansky population.
