I am a Professor of International Law at the University of Exeter. My research focuses on public international law, especially international cyber law, international humanitarian law, and the regulation of emerging technologies. I am particularly interested in how international law applies to cyber activities and artificial intelligence, and more generally how it adapts to evolving strategic and technological realities.

I currently serve as General Editor of the Cyber Law Toolkit, the award-winning interactive online resource on international law and cyber operations. I am also a co-author of the Handbook on Developing a National Position on International Law and Cyber Activities: A Practical Guide for States, published in 2025. My work has appeared in journals such as the International & Comparative Law Quarterly, International Review of the Red Cross, the Journal of Conflict and Security Law, and the Chinese Journal of International Law. During my academic career, I have held research fellowships in China, Germany, Israel, the Netherlands, and Switzerland.

I hold a DPhil in international law from the University of Oxford (Somerville College), supervised by Professor Stefan Talmon. A revised and expanded version of my doctoral thesis was published by Oxford University Press as Internationalized Armed Conflicts in International Law in 2018. I have also studied at Charles University in Prague and at KU Leuven in Belgium. In 2012, I was awarded the Diploma of the Hague Academy of International Law, where I later served as Director of Studies in 2024.

Earlier in my career, I worked at the UN International Criminal Tribunals for the former Yugoslavia and Rwanda, and at the Slovak Constitutional Court as a law clerk to its president. From 2019 to 2023, I served as Legal Adviser at the International Committee of the Red Cross, contributing to the Updated Commentaries on the Geneva Conventions and to the ICRC’s work on international humanitarian law and cyber operations.
