I am a professor for informatics at Universität Bremen and head of the cognitive systems group (CoSy). My research interests focus on knowledge representation, specifically on the representation of spatial and temporal knowledge and on reasoning with qualitative, approximate, incomplete, imprecise, fuzzy, uncertain, and conflicting knowledge. In the CoSy research group we employ formal and computational approaches to knowledge representation, we design computer models of spatial environments for simulation studies, and we carry out autonomous robotic experiments in our spatial environment laboratory using diverse intelligent technologies. We closely cooperate with researchers from other disciplines interested in the investigation of spatial structures, especially cognitive psychology, linguistics, geography, and design. I coordinate the Transregional Collaborative Research Center Spatial Cognition - Reasoning, Action, Interaction (SFB/TR8), a joint enterprise of the Universities of Bremen and Freiburg funded by the Deutsche Forschungsgemeinschaft (DFG) and the International Quality Network on Spatial Cognition (IQN) funded by the German Academic Exchange Service (DAAD). In my previous position at Universität Hamburg (1991-2002) I coordinated the DFG Spatial Cognition Priority Program and participated in the EU HCM project Spacenet.
