Between November 10th and 13th the 4th project meeting of the DECADES consortium took place in Groningen. This time the host was Prof. Marco Fraaije in the recently inaugurated building Feringa Building of the University of Groningen. Besides the presentations of the PhD students about their projects and their progress, we were able to visit Marco’s labs. In the evening we were able to get a culinary insight into Groningen and talk in detail about the progress and developments in the individual projects.
