My current main research focus is on Knowledge Graphs, including all theoretical and practical aspects. In particular, I am interested in reasoning in such systems, including all of the AI methodologies for that (knowledge-based/logic-based reasoning and machine learning-based reasoning). Within such systems, my interest in achieving scalable solutions, making sure that theory translates into practice.
More on this topic can be found at the website of the Knowledge Graph Lab (kg.dbai.tuwien.ac.at) at TU Wien, which I lead.
More broadly, my research interests are on scalable knowledge-based information systems and artificial intelligence technologies, in particular on aspects touching both theory and practice. On the theoretical side, this includes the theory of scalable systems, logic, reasoning and complexity. On the practical side this includes database management systems, scalable database and information systems, and knowledge management platforms.
For emails in my role of Vice Dean of Academic Affairs for Business Informatics and Data Science, please write primarily to <studiendekanat.informatik@tuwien.ac.at> mentioning that your request is for me, I can get back to you more quickly in that way.
