I obtained a Master degree in Applied Physics from Eindhoven University of Technology in the Netherlands in 1993. In 1998 I received a PhD from the same university (Thesis ‘Many-body effects in the valence bands of two-dimensional heterostructures based on III/V semiconductors’). After that I was awarded a 5-year post-doctoral fellowship from the Netherlands Academy of Arts and Sciences (KNAW) to work on scanning tunneling spectroscopy and STM-induced luminescence. During this fellowship I shifted my attention from inorganic, highly crystalline semiconductors to organic, amorphous or polycrystalline semiconductors. I became assistant professor in 2003 and associate professor in 2009. As of 2014 I have been appointed full professor in Applied Physics at the Department of Physics, Chemistry and Biology (IFM) at Linköping University in Sweden, where I lead the group Complex Materials and Devices (CoMaDe).
My research interests range from fundamental charge and energy transport in disordered, mostly organic semiconductors, to device concepts and applications based on these materials. The group's websites and the publication list below should give a reasonable indication of what this means in practice.
