... graduated in Physics at "La Sapienza" University of Rome. Over the years, she has taken part in several experiments in Italy, Europe and the USA. She has often been asked to assume positions of great responsibility. Specifically, she has coordinated activities in accelerator physics and led the research division at the INFN Frascati National Laboratories. Maria joined ATLAS in its design phase, participating in the layout, development, testing, construction and installation of the detectors for precision-tracking of muons. Indeed, she has played a key role in making the muon detector a reality. The ATLAS community recognised her capabilities when, in 2007, it elected her as the Italian scientist responsible for the experiment.
