I am a research assistant currently working at University of Bremen. For the academic year 2014-2015 I worked in Stockholm University and Technical University of Denmark. From August 2013 until July 2014 I had a position in the University of Wroclaw with EU funding from the European Research Consortium for Informatics and Mathematics (ERCIM).

Research interests:
  • Decidability and complexity of fragments of first-order logic
  • Team semantics and variants of dependence logic
  • Descriptive complexity theory for distributed computing
  • Model theory of modal logic and finite model theory
