Physicist Laura Marini is run co-ordinator and site manager of the Cryogenic Underground Observatory for Rare Events (CUORE). Operated by an international collaboration, the experiment is situated deep beneath a mountain in Italy’s Abruzzo region at the Gran Sasso National Laboratory of the National Institute of Nuclear Physics. Marini received a PhD in physics from the University of Genoa in 2018 and then did a postdoc at the University of California, Berkeley. She began working on CUORE during her PhD and today she is affiliated with Italy’s Gran Sasso Science Institute and the Gran Sasso lab. Marini spoke to Richard Blaustein about her role at CUORE and the experiment’s recent milestone in its ongoing investigation of whether neutrinos are Majorana particles.
