I am a senior lecturer at the Database and Artificial Intelligence Group of TU Wien and hold a venia docendi at the University of Vienna (Faculty of Computer Science). Before that, I was with the Theory and Applications of Algorithms Group at the University of Vienna and even before I obtained my PhD at TU Wien, within the WWTF funded project "New Methods for Analysing, Comparing and Solving Argumentation".Current Work and Research Interests
My research interests lie in theoretical computer science and my main research area is on Algorithms and Algorithmic Lower Bounds for Graph Problems from Applications, with the current focus being on problems in Artificial Intelligence and model checking problems from computer aided verification. In my research, I apply methods from the fields of algorithms and computational complexity theory, in particular from the research areas of parameterized complexity, approximation algorithms, and conditional lower bounds. Beyond that, I am interested in research on the intertranslatability and expressiveness studies of AI formalisms. Find below a list of some topics I'm interested in.- (Analysis of) Algorithms
- Approximation Algorithms
- Complexity Theory and Complexity Analysis
- Conditional Lower Bounds
- Parameterized Complexity
- Knowledge Representation and Reasoning
- (Abstract) Argumentation
- Graphs and Graph Parameters
- Games on Graphs
- Answer Set Programming
- ...
