Alessandro Ratti serves as the Division Deputy for accelerator technologies in the Engineering Division at Lawrence Berkeley National Laboratory (LBNL). His journey in the particle accelerator field has seen him take on increasingly vital roles. Notably, he led the electronics team in completing the front end injector for Spallation Neutron Source at Oak Ridge National Lab. Subsequently he led a significant US contribution to beam instrumentation systems for the Large Hadron Collider (LHC) at CERN, and then he was instrumental in the demonstration of the crab cavity system in the US, which is now an integral part of the LHC upgrade project. Presently, Alessandro is the system manager of electronic systems for the ALS Upgrade. Prior to this position, he served as the director of the Electronics Engineering Division in the Accelerator Directorate at SLAC. His technology innovation efforts at LBNL earned him and his team an RD100 award for the development of the Unexploded Ordnance Discriminator, and later patented the technology for ground water exploration.

Alessandro holds a degree in Electronics Engineering from the University of Pavia and an MBA from the Haas School of Business. These credentials empowered him to contribute significantly to the founding of several successful startups, including playing a key role as the co-chair of the founding board that initiated the Bay Area Chapter of ISSNAF in 2017. In recognition of his service to Italy and the scientific community, Alessandro was honored with knighthood as Cavaliere Ordine al Merito della Repubblica Italiana.
