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 recently completed a 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 project aimed at establishing whether the resolutions of the United Nations General Assembly contribute to the creation of customary international law. The research methodology adopted combines empirical with normative and doctrinal analysis.

I was a Visiting Scholar at the Lauterpacht Centre for International Law, University of Cambridge from July to September 2017.

From 1 June to 31 August 2018, I will be a Scholar-in-Residence at the Library of Congress, Washington DC, U.S.A.
