I am offering a PhD position for my WWTF research project titled Structural and Algorithmic Aspects of Preference-based Problems in Social Choice. See the offer for more information.

I am an assistant professor at the Institute of Logic and Computation of the Faculty of Informatics at TU Wien, Austria.

I lead the 2018 VRG-ICT research project Structural and Algorithmic Aspects of Preference-based Problems in Social Choice, funded by the Wiener Wissenschafts-, Forschungs- und Technologiefonds (WWTF).

My research interests are the parameterized complexity of, and the design and analysis for, combinatorial problems arising in contexts such as

  • Optimization problems related to graphs and hypergraphs
  • Computational Social Choice:
    • Computational problems around voting
    • Domain restrictions
  • Preference-based stable matching problems


From October 2011 till March 2014, I was supported by Studienstiftung des Deutschen Volkes.
