Dr.-Ing. Tim Grunwald

Tim Grunwald first graduated with a bachelor´s degree in Mechanical Engineering. He subsequently completed a master´s degree in Automation Technology at the Rheinisch-Westfälische Technische Hochschule (RWTH University) Aachen, specializing in the production of optical components.

In May 2016 he began working in the »Optics« group at the Fraunhofer IPT and subsequently took over the management of this group for a fixed period of one year. He has led »Precision Machining and Optics« Department since February 2019.
