Overview Research Education Contact
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.
Expertise Chemistry Surface Liquid Film Energy Ion Scattering Material Science Physics Organisations My research focuses on the application of surface analysis techniques to (i) study thin film growth, with a focus on XUV optics applications and (ii) study interaction of plasma, ions and radicals with thin film surfaces.
