This webpage contains information on my former activities as a faculty
member at the Instituut-Lorentz in the physics department (LION) of
Universiteit Leiden, as on November 1 2009 I became director of the physics foundation FOM and have stopped my research and teaching at the Instituut-Lorentz. From June 2015 till December 2016 I am leading the organisational change of our national science foundation NWO. On January 1 2017 I will return to the Instituut-Lorentz as a professor, combining this position with that of vice-president and president-elect of the Royal Society KNAW.
