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 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 2020).

I was a 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).
