I am a full professor at the Institute for Theoretical Physics at Utrecht University on the chair "Theory of Nanoscale Systems", and part-time professor (in Dutch: "deeltijdhoogleraar") on the chair "Theory for Spin-based Nanoelectronics" at Eindhoven University of Technology, in the group Physics of Nanostructures. My current research is focused mostly on spintronics: the research discipline concerned with exploiting the spin degree of freedom of the electron in applications. Spintronics combines efforts of materials nanoscience, nano-electronics, and condensed-matter physics. My expertise is in theoretical condensed-matter physics.
