Roman Truckenmüller holds an engineering diploma and a doctorate in engineering science from the Universities of Stuttgart and Karlsruhe, Germany, respectively. After working as a development engineer for Siemens in Erlangen, Germany, he worked at the Institute for Microstructure Technology (IMT) of Karlsruhe Institute of Technology (KIT). At IMT, he carried out his doctoral project on fabrication of three-dimensional microstructures from polymer membranes, worked as a postdoctoral researcher in the field of X-ray lithography and headed a research group dealing with membrane-based microfluidic sensors and actuators from polymers. From 2007 on, he worked at the Department of Tissue Regeneration (TR) of the University of Twente, The Netherlands, where he was appointed assistant professor in 2010. In 2014, he changed over to the successor of TR now at Maastricht University, the newly founded MERLN Institute for Technology-Inspired Regenerative Medicine, where he works as an associate professor at the Department of Complex Tissue Regeneration (CTR). His research at CTR focuses on micro- and nanoscale 3D polymer film forming and functionalization technologies and their biomedical applications, with a particular focus on engineering of complex artificial cellular microenvironments for advanced in vitro model systems using the aforementioned technologies. Roman Truckenmüller is one of three founders of the start-up company 300MICRONS spun-off from KIT in 2015 and dealing with advanced 3D cell culture solutions based on proprietary platform technologies.
