Biography

Thomas Wiemann is currently a post-doc at the Knowledge Based Systems group at the University of Osnabrück. He received his doctorate degree (Dr. rer. nat) in 2013. His thesis dealt with the automatic generation of polygonal maps from point cloud data for robotic applications. His current research concentrates on making these methods applicable for large scale environments and multi sensor systems. The main focus of his work is to generate multi-modal maps that can be used on mobile robots in different contexts. That includes standard problems like localization and path planning as well as semantic interpretation of the input data for symbolic processing. For his master thesis he received the Karman Innovation Award at Osnabrück University in 2007. For his work on open source software he received the Intevation Free Software Award at Osnabrück University in 2014. Since 2017 he is vice chair (on social media) of the IFAC Technical Commitee TC 7.5 on Intelligent Autonomous Systems.
