I studied Applied Physics at Eindhoven University of Technology in the Netherlands, after which I obtained my PhD at the University of Twente in 2006. After 2 years of post-doc at the Fritz Haber Institute of the Max Planck Society in Berlin (Germany), I joined the FOM Institute for Plasma Physics Rijnhuizen in Nieuwegein (the Netherlands). Since 2014, when the current XUV group moved from Nieuwegein to the University of Twente, I have been senior staff member in the XUV group.

Throughout my career I developed a strong background in surface analysis, thin film fabrication and surface chemistry studies.
