Fabian serves as a Charles & Katharine Darwin Research Fellow at Darwin College, University of Cambridge, and is also a Fellow at the Lauterpacht Centre for International Law. His primary research interests span general international law—with a particular emphasis on dispute settlement and state responsibility—international investment law, international environmental law, and German public law. At present, his research focuses on national security, climate change, and the functions of international courts within the global legal architecture. He is a co-editor of the Edward Elgar Research Handbook on State Responsibility in the 21st Century (forthcoming 2025).

Between 2020 and 2023, Fabian wrote his PhD on "Self-Judgment in International Law", funded by a W.M. Tapp Studentship and the German Academic Scholarship Foundation.

He completed his legal studies at Bucerius Law School, Hamburg (Dipl. Jur.), Waseda University, Tokyo (exchange), and the University of Oxford (M.Jur.). In 2022, he received the Rosalyn Higgins Prize from The Law and Practice of International Courts & Tribunals for his article on ‘Informal Communications to the International Court of Justice in Cases of Non-Appearance’.

Fabian has supervised undergraduate students (B.A. in Law) in Human Rights Law and International Law. He has also led workshops for Cambridge LL.M. students in subjects such as International Law of Global Governance, International Investment Law, and International Law as a Legal System. His teaching experience extends to German constitutional law at the University of Heidelberg and Humboldt University, Berlin.
