Brief Bio

I am a Feodor Lynen Postdoctoral Research Fellow funded by the Humboldt Foundation and I am affiliated to the Centre for Quantum Computation & Intelligent Systems at University of Technology Sydney as a visiting fellow.

Prior to joining UTS, I was a research fellow in the Artificial Intelligence group of the Research School of Computer Science at the Australian National University. Before that I was based in Germany and was a member of Cognitive Systems Group at University of Bremen, working in the project R3 of the Transregional Collaborative Research Center 'Spatial Cognition'. I was also affiliated to the International Research Training Group on Semantic Integration of Geospatial Information.

I received my doctoral degree in computer science from the University of Bremen in October 2013, where a part of my doctoral research was carried out at the University at Buffalo and at North Carolina State University. I received my Diplom (MSc equivalent) in mathematics from University of Bremen in 2009.

Research

I am interested in Spatial Reasoning in the sense of deductive (i.e., rule-based) reasoning as well as in the sense of inductive (i.e., data-based) reasoning. This research is motivated by applications in the areas of geographic information systems, computer-aided design, and artificial intelligence.

I am currently working on the topic Spatial Constraint Reasoning with Preferences. So far, Spatial Constraint Reasoning and Preferences have been two distinct AI research areas. It is therefore an interesting research question how one can (i) integrate the representations from the two areas and (ii) apply the new representations to practical situations. Since such an integration comes usually at the expense of increased computational complexity for reasoning, my research focus is on achieving integrations that provide reasoning methods that are efficient in practice.
