Lucia Leontiev is an EUI Civica Fellow at the European University Institute, Italy. She was previously a Max Weber Fellow at the European University Institute (Italy) and a post-doctoral fellow at the Berlin Potsdam Research Group ‘International Rule of Law-Rise or Decline?’ (Germany). She is a generalist international law scholar. Her research focuses on the law of statehood, jurisdiction, human rights law, and the interaction between national and international legal orders, as well as between public and private international law—topics on which she has also published. She is currently exploring the role of geopolitics in the evolving international legal order. Her most recent work is the co-edited volume Extraterritoriality Around the Globe: Multiform Approaches in a Multipolar World (Routledge, 2025), a comprehensive collection that examines the evolving role of extraterritoriality in international law within a changing global landscape. Lucia holds a PhD in international law from the University of Maastricht and the Sant’Anna School of Advanced Studies in Pisa (double doctoral degree). She is an alumna of the Hague Academy of International Law and of the International Law Seminar organised by UNOG in connection with the annual session of the International Law Commission (ILC). Lucia has worked for the European Court of Human Rights, the Human Rights Council in Geneva, and the Ministry of Justice of the Republic of Moldova. She has delivered guest lectures and held visiting teaching positions at several universities, including the IE University, Catholic University of Lyon and the OSCE Academy in Bishkek.
