Enrico has 30 years of experience at CERN. His initial expertise lay in high-security and high-reliability systems. Over the decades, Enrico has evolved as an environmental and sustainability engineer. During his first decade at CERN, Enrico played a pivotal role in maintaining and upgrading the accelerator’s access safety and control systems. His expertise led to his appointment as the Project Engineer for the Large Hadron Collider (LHC) Access Control and Safety Systems where he oversaw the feasibility and design phases. In his second decade, in the framework of the CERN’s LHC and CNGS operation licensing process, Enrico served as Editor-in-Chief for the safety documentation requested by the CERN host States Authorities. During the last decade, Enrico took on broader responsibilities, becoming Head of the Safety Engineering and Environment Group in CERN’s Health, Safety, and Environment (HSE) Unit. Between 2018 and 2020, he led the CERN Environment Steering Board, where he played a part in shaping CERN’s environmental strategies. He led also the newly created Environment Group, spearheading the development of CERN’s first two public-facing Environment Reports. Since 2021, Enrico is the Project Leader for CERN’s Environmentally Responsible Procurement Policy Project (CERP3) within the CERN Procurement Group. In this role, he is driving efforts to implement environmentally responsible procurement and progressively sustainable practices within CERN’s procurement processes.
