Marc J. J. Vrakking received his Ph.D. from the University of California, Berkeley, in 1992 and has been a group leader at the FOM Institute for Atomic and Molecular Physics (AMOLF) in Amsterdam since 1997. His research concentrates on the development and application of attosecond laser pulses to study time-resolved electron dynamics, as well as the use of free electron lasers for studying molecular fragmentation processes and the interaction of atoms and molecules with intense laser fields. Since 1 September 2004 he has had an appointment at the Radboud University Nijmegen. In 2005 he was the recipient of an NWO VICI award. In EU Framework Programme FP7 he coordinates the “ATTOFEL” (Ultrafast Dynamics using ATTosecond and XUV Free Electron Laser Sources) Initial Training Network, where Ph.D. students are trained in the areas of attosecond and XUV/x-ray free electron laser science at ten participating partner institutions.
