Leonida Antonio Gizzi received his Laurea in Physics from the Università di Pisa (1989) and his Ph.D. in Plasma Physics from Imperial College London (1994). He is currently Research Director at the Istituto Nazionale di Ottica (CNR-INO), Pisa, and Scientific Director of the Intense Laser Irradiation Laboratory (ILIL). In 2025, he was nominated Director of Science of ELI-ERIC. His research spans high-power laser–matter interaction, laser-driven particle acceleration, inertial fusion energy, and VHEE-based FLASH radiotherapy. He has authored over 320 publications (H-index 47, Google Scholar) and supervised more than 20 researchers. He serves as Chair of the EPS Beam Plasma and Inertial Fusion Section and has led numerous European projects including EuPRAXIA, HiPER, and I.FAST.

       This lecture presents the scientific and technological capabilities of the three ELI facilities — ELI ALPS, ELI Beamlines, and ELI-NP — highlighting their complementarity across a broad range of laser parameters and applications. Together, they form a unique platform covering repetition rates from single-shot to 100 kHz, pulse energies from millijoules to tens of joules, and pulse durations down to a few femtoseconds. ELI ALPS focuses on ultrafast and attosecond science, enabling electron dynamics studies on timescales of 10⁻¹⁸ seconds. ELI Beamlines specializes in high-energy, petawatt-class laser systems producing laser-driven secondary sources including X-rays, electrons, and ions. ELI-NP is dedicated to nuclear physics and high-field science using a 10 PW laser combined with a high-brilliance gamma-beam system, bridging laser and nuclear physics for frontier multidisciplinary research.
