Activity

EP is Senior Scientist and beamline coordinator at the FERMI Free Electron Laser.

EP designed the TIMEX beamline and is currently responsible for its operation and development. Typical experimental configurations at TIMEX include pump-probe setups (synchronizing FEL and fs-laser pulses), ultrafast optical and EUV spectroscopies, and in particular sub-picosecond time-resolved X-ray absorption spectroscopy (tr-XAS). More recently, further disruptive techniques have been implemented at TIMEX, such as: i) ASE spectroscopy from high-pressure gases exposed to EUV light, ii) EUV second harmonic generation, iii) impulsive stimulated Raman scattering combined with tr-XAS, iv) superradiant Thomson scattering.

Main research interests include:

• femtosecond electronic processes in photo-excited functional materials,
• condensed matter under fs-laser-driven extreme conditions of temperature and pressure,
• non-linear soft X-ray spectroscopies for probing interfaces in materials,
• electronic structure in solid-density plasmas,
• ultrafast chemical reactions.

EP collaborates with the FERMI team on the commissioning and development of the facility. Moreover, he contributes to the Elettra 2.0 upgrade, focusing on the definition of high-impact experiments enabled by the ~1 picosecond, MHz pulse emission of the upgraded synchrotron.

EP has served as Guest Editor for the Structural Dynamics Special Topic entitled "The Advent of Ultrafast X-ray Absorption Spectroscopy" and the Applied Sciences Special Issue entitled "Latest Trends in Free Electron Lasers".

Committees, Advisory Boards & Panels

• Member of the Steering Committee and Work Package Leader of the European Project EuPRAXIA (Preparatory/Implementation Phase), aimed at designing and operating distributed user facilities based on plasma acceleration technology. (EP has recently published a perspective article entitled "A roadmap for strategic pilot experiments at the first plasma-driven x-ray FEL").
• Member of the EuPRAXIA@SPARC_LAB Scientific Advisory Committee.
• Co-author of the Technical Design Report of the plasma-driven soft X-ray FEL EuPRAXIA@SPARC_LAB.
• Member of the Working Group for the Technical Design of the photon beamlines and user stations at the laser-driven soft X-ray FEL at ELI Beamlines.
