University Prof. Dr.-Ing. Christian Hopmann has been Head of the IKV - Institute for Plastics Processing in Industry and Craft at RWTH Aachen University and Managing Director of the IKV's Association of Sponsors since 2011. He also holds the Chair of Plastics Processing at the Faculty of Mechanical Engineering at RWTH Aachen University.Christian Hopmann studied Mechanical Engineering with a particular focus on Plastics Processing at RWTH Aachen University. He received his doctoral degree with a thesis on Ceramic Injection Moulding. He held various prominent positions at the IKV before starting his industrial career as Head of Quality Management at RKW SE in 2005. From 2010 to 2011 he was Managing Director of RKW Sweden AB in Helsingborg/Sweden. Prof. Dr. rer. nat. Rainer Dahlmann is Head of the Center for Analysis and Testing of Plastics (KAP) and Scientific Director at the IKV. He studied Physics with a focus on Solid State Physics at RWTH Aachen University. He received his doctorate from the Faculty of Mechanical Engineering at RWTH Aachen University in the field of Plasma Technologies. Since 2007, he has lectured in the Bachelor's and Master's programs in Applied Polymer Sciences at the FH Aachen, and in Mechanical Engineering and Plastics and Textile Technology at RWTH Aachen University.
