Riccardo Longo

Biography

Dr. Riccardo Longo received his Ph.D. from the University of Turin in 2018, with a thesis on spin effects in pion-induced Drell-Yan reactions at the COMPASS Experiment at CERN, including the first-ever measurement of the Transverse Spin Asymmetries of the Drell-Yan cross-section. After his graduation, he became a post-doc at the University of Illinois at Urbana-Champaign (UIUC) and spent 1 year at CERN working on COMPASS data analyses and supercomputing applications before moving to the US, where he joined the Nuclear Physics Lab effort in the Heavy Ion program of the ATLAS Experiment at CERN. He is currently a Research Scientist in the UIUC Physics Department, and he serves as Technical Coordinator of the ATLAS Zero Degree Calorimeter, project leader for the ATLAS Reaction Plane Detector, and Co-principal investigator and project manager of the joint ZDC upgrade for the ATLAS and CMS experiments for the High-Luminosity LHC. His hardware involvement is closely related to his physics interests, which encompass a wide array of jet-based measurements to study hot and cold QCD effects emerging in nucleus-nucleus and proton-nucleus collisions.
