Congrats Dr. Heiko Knopf to your resounding success. The former Max Planck School of Photonics student and scientist of the Friedrich-Schiller-Universität Jena and Fraunhofer IOF was elected vice chairman of the Green Party of Germany.
I am sure that Dr. Heiko Knopf will embody the same kind of sincerity and integrity in politics that made him a great scientist and supremely productive member of my research group. Foremost this is not a loss for my research group, but a gain for the country and your party.
I am supremely proud that I was able to supervise you in the last three years and to have witnessed you writing a successful PhD-thesis, defence, and election campaign with half a year. Politics needs more science and we all know there is room the top for ambitioned Physicists.
