Alessandro Rizzo attended the University of Rome “Tor Vergata” in Italy and graduated in 2009 with a master degree in Nuclear Physics. He started his scientific activity by joining the SIDDHARTA collaboration at Laboratori Nazionali di Frascati (INFN), focusing his attention on the mesonic atoms and the study of the strong interaction at low energy. He received his PhD from the University of Rome “Tor Vergata” in 2012 presenting a thesis on X-ray measurement of the kaonic hydrogen system. At the end of 2012 he has won a Post-Doc position at University of Rome “Tor Vergata” and has joined the CLAS collaboration at Thomas Jefferson National Laboratory in Virginia, USA. The main research field is the nucleon structure investigated with electromagnetic probes. He is particularly involved in the search of hybrid hadrons, bound states of quarks and gluons not predicted by standard theories. In the framework of spin-polarized targets production for CLAS/CLAS12 experiments, since 2012 he takes care of Raman spectroscopy measurements of distilled HD gas, whereas for the CLAS experiment upgrade, CLA12, he followed the characterization of new silicon detectors. Since 2013 he joined the HPS (Heavy Photon Search) collaboration at Jefferson Laboratory, aiming to investigate the existence of a hypothetical dark matter particle, a massive photon. Since 2012 he is assistant professor at University of Rome “Tor Vergta” for the laboratory courses. He attended several international conferences and he has over 50 publications on referred international journals.
