The interaction zone between industry and Big Science has been the focal point for Nikolaj Zangenberg’s activities over the last 15 years. He is in charge of the Big Science Center at the Danish Technological Institute where he has worked with companies both “upstream” (suppliers) and “downstream” (users). On the upstream side, he has served as Industrial Liaisons Officer (ILO) for Denmark at CERN, ESRF, ILL and European-XFEL. He has also co-founded the Danish ILO initiative, BigScience.dk, that manages a network of 350 Danish suppliers to the Big Science market. On the downstream side, DTI operates as a commercial mediator for industry, and Nikolaj is project coordinator for the EU project EASI-STRESS linking industry to residual stress measurement at neutron and synchrotron facilities.
