History and Theory of International Law Researchers

Ingo Venzke
Ingo Venzke
Hauser Research Scholar

Ingo Venzke is completing his PhD “On Words and Deeds. How the Practice of Legal Interpretation Develops International Norms” at the University of Frankfurt under the supervision of Armin von Bogdandy. His thesis builds on considerations of semantic pragmatism and it elucidates the agency of international actors in processes of communicative lawmaking. At NYU he will now focus on the power of international courts, on how their authority can be justified, and on how it may be dealt with in the interaction between different levels of governance.
Ingo has been a Research Fellow at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg and a Visiting Scholar at Tel Aviv University. He holds a LL.M. with distinction from the University of London (SOAS) and a B.A. in International Relations from the School of International Studies in Dresden. The German Academic Exchange Service also supports Ingo’s post-doctoral research.
