Research Interests

Anything graphs, e.g.:
  • Graph Algorithms
  • Graph Theory
  • Graph Mining
Anything at the interface between (theoretical) computer science and the social sciences.
As a recovering lawyer, I sometimes do legal data science projects, too.


  • A Breezing Proof of the KMW Bound (with Christoph Lenzen). To appear in SOSA 2021. PDF (Extended Version)
    We give a simple and (in the extended version) fully self-contained proof of the KMW lower bound, proving a hardness result for several fundamental graph problems in the LOCAL model of distributed computing.

  • Complex Societies and the Growth of the Law (with Janis Beckedorf, Dirk Hartung, and Daniel Martin Katz). Sci. Rep. 10 (2020), 18737:1-18737:14. PDF Appendix
    We examine 25 years of statutory legislation in the United States and Germany through the lens of network science, finding that the main driver behind the growth of the law in both jurisdictions is the expansion of the welfare state, backed by an expansion of the tax state.

  • Das Wertpapierhandelsgesetz (1994–2019): Eine quantitative juristische Studie (with Andreas Martin Fleckner). Festschrift 25 Jahre WpHG (2019), 53-85. PDF Appendix
    A legal data science project investigating the evolution of Germany's Securities Trading Act over the first 25 years of its lifetime.

  • Juristische Netzwerkforschung : Modellierung, Quantifizierung und Visualisierung relationaler Daten im Recht.
    XVIII, 376 p. Tübingen: Mohr Siebeck (2019). PDF Appendix
    Awards: Otto Hahn Medal of the Max Planck Society (2020), Bucerius Law School Dissertation Award (2018)
    My legal dissertation. I introduce network science to the German legal discourse and explore what "legal network science" could mean. This is how I got into graphs.

  • Quantitative Rechtswissenschaft : Sammlung, Analyse und Kommunikation juristischer Daten (with Andreas Martin Fleckner). Juristenzeitung 73 (2018), 379-389. PDF Appendix
    We explain what legal data analysis is and discuss how German legal research could profit from it.
