Kasra Amini: Kasra completed his Ph D at University of Oxford in 2017 on laser-induced Coulomb explosion imaging and postdoctoral positions on laser-induced electron diffraction at The Institute of Photonic Sciences (ICFO, Barcelona). Since 2021, Kasra is the junior group leader of the ultrafast electron diffraction group (UED) at Max-Born Institute (MBI, Berlin), focussing on high repetition rate UED imaging of transient gas-phase and condensed matter structures with high temporal resolution. Arnaud Rouzée: Arnaud has expertise in ultrafast laser science, atomic and molecular spectroscopy, nonlinear optics, strong field physics and X-ray science.  Dr. Rouzée is an expert on the fundamentals and applications of strong-field physics in ultrafast molecular science, including the development of novel methods to image coherent electronic and nuclear dynamics. Marc J. J. Vrakking: After completing his Ph D at the University of California at Berkeley in 1992 and postdoc positions at the National Research Council (Ottawa) and the Vrije Universiteit Amsterdam, Prof. Marc Vrakking led a scientific group at the FOM Institute for Atomic and Molecular Physics (AMOLF) in Amsterdam from 1997 to 2011, focusing on the use of ultrashort (femtosecond and attosecond) extreme-ultra-violet (XUV) and X-ray laser pulses in studies of time-resolved atomic and molecular dynamics. In March 2010, he was appointed as director at the Max-Born Institute (MBI) in Berlin, and as a professor of physics at the Freie Universität Berlin. At MBI, Marc Vrakking is the head of Division A (“Attosecond Science”) and leads a team of researchers that are both further developing and applying techniques to study electron dynamics on attosecond timescales as well as nuclear dynamics on femtosecond timescales.
