I am Ali Soleimani, a PhD student within the QU-ATTO network, currently hosted at Elettra Sincrotrone Trieste (FERMI free-electron laser). I obtained my BSc and MSc in Physics from Shiraz University, Iran, where I developed a strong background in quantum mechanics and light–matter interaction. My PhD project focuses on attosecond pulse shaping and control in seeded free-electron lasers, with particular emphasis on echo-enabled harmonic generation (EEHG). My research combines theoretical modeling, numerical simulations, and experimental studies of EEHG at FERMI, with close links to FEL beam dynamics and machine operation. I mainly use GENESIS and MATLAB/Python for FEL simulations and diagnostics. My research interests include ultrafast electron dynamics, multi-color FEL generation, and coherent control at the attosecond timescale, with the aim of enabling advanced spectroscopy experiments using tailored FEL pulses.
