Personal details

Laurea in Scienze giuridiche (LLB), Laurea in Giurisprudenza (LLM), PhD

I joined the University of Leicester in September 2015. My research interests lie in the field of public international law and international legal theory.

I have been Visiting Scholar at the Lauterpacht Centre for International Law, University of Cambridge (2017) and Scholar-in-Residence at the Library of Congress, Washington DC, U.S.A. (2018 and 2019). I have presented at the 12th Stanford International Junior Faculty Forum (2019).

My publications have appeared in the International and Comparative Law Quarterly, the Leiden Journal of International Law and the German Yearbook of International Law. I am the co-editor of the handbook on Research Methods in International Law (Edward Elgar 2021). I have also edited the volume Pluralising International Legal Scholarship: The Promise and Perils of Non-doctrinal Research Methods (Edward Elgar 2019).

My monograph on the strategic use of international law by the United Nations Security Council. By employing a quantitative research methodology, the book provides the first comprehensive empirical study of the practice of the Security Council from the origins up to the present. Professor André Nollkaemper, President of the European Society of International Law, described the book as ‘an all too rare attempt to bring empirical legal studies to international law'.

I am currently working on a monograph for Cambridge University Press entitled: Empirical and Theoretical Perspectives to International Law: How States Use the UN General Assembly to Create International Obligations (forthcoming 2022).
