Research

My research can be characterized by two sub-areas of Artificial Intelligence, namely knowledge representation and cognitive agents. I investigate representations that allow cognitive agents, assistance systems, or software agents situated in the real world to represent their environment and to reason about it. Dealing with coarse, uncertain, and even conflicting knowledge is of key interest to me. I take a broad interpretation of the term reasoning to encompass all rational tasks required by a cognitive agent, in particular planning and recognition of context, actions, and events as well as learning and deduction. I am developing the spatial reasoning toolbox SparQ and I am likewise interested in beautiful theories and efficient algorithms. So far, I have contributed to these research areas:

  • Qualitative spatial and temporal reasoning
  • Knowledge representation, symbolic reasoning
  • AI robotics, mobile robot localization, mapping, and navigation
  • Semantics of natural language, referring expression generation
  • Shape retrieval in computer vision

Teaching

Please consult UniVIS as well as these web pages for courses related to smart environments and have a look at the suggested topics for theses (webpages in German).

Publications

Please consult my complete list of publications. If you find interest in a paper you cannot access, please don't hesitate contacting me! There is also a public Google scholar bibliography of mine as well as bibliography on ResearchGate, neither of which receiving much care.
