I am a generalist international lawyer with a research focus on international institutional law, the United Nations system, and the rule of law within and beyond the state. My current research focuses on how the rule of law was conceptually shaped in the UN system and highlights the UN Secretariat’s role in operationalizing it. I also have an active research agenda on the potential of quantitative text analysis to study normative developments at the UN.
My book The Rule of Law in Germany: Bringing the Rechtsstaat into the 21st Century (with Dana Burchardt) was published in Hart’s Rule of Law in Context book series in 2025.
I have in the past conducted research on how international courts manage overlapping legal regimes as part of a multi-year interdisciplinary research group on Overlapping Spheres of Authority and Interface Conflicts, and on the UN’s 2030 Agenda on Sustainable Development, especially on Goal 5 (gender equality), Goal 11 (cities and human settlements), and Goal 16 (peaceful and inclusive societies).
