Marina graduated in physics from the University of Rome ‘La Sapienza’, where she worked on the data acquisition system for the UA1 experiment. She has since worked on detector electronics, triggers and data acquisition systems at CERN and INFN, collaborating on experiments at the OMEGA facility and the KLOE experiment in Frascati, before joining the CMS collaboration. She has been a technologist at INFN's Padua section since 1998, the year in which she joined the CMS collaboration. She developed controls for the construction and testing of the DT chambers and subsequently managed their commissioning at CERN as a Scientific Associate. She then became the FOG coordinator in the Trigger Strategy group.

She participated in several data-taking campaigns as an expert on call, shift leader and run field manager. Since 2015, she has been involved in outreach and communication activities, including acting as a CMS guide, participating in a TV show about Italian physicists at CERN and contributing to the organisation of science communication events such as Researchers' Night and International Radon Day. Her responsibilities have included photo and video documentation, creating summary videos, video editing and moderation. She also participated in the Radiolab project to train high school students. She has also contributed to the 'Stories of Physics and Physicists' and 'Art&Science' INFN events by producing video material and photo documentation, and by judging the works. She is currently Deputy Head of External Communication for the CMS experiment.
