Sergio Dellavalle is Professor of Public Law and State Theory at the University of Turin, Italy, Visiting Fellow at St Edmund’s Colle, University of Cambridge, and Senior Research Affiliate at the Max Planck Institute for Comparative Public Law and International Law (MPIL) in Heidelberg, Germany. He has been Marie-Curie-Fellow of the European Commission, Fellow of the DAAD, Senior Research Fellow at the MPIL, as well as Visiting Fellow at The Buchmann Faculty of Law of the Tel Aviv University, the Lauterpacht Centre for International Law (University of Cambridge) and Rutgers University (NJ). He has been Visiting Professor at the Universities of Tübingen, Heidelberg and Frankfurt, and held guest lectures at the Universities of Baltimore, Queen’s Belfast, Cardiff, Lehigh (PA) and Wilmington (DE). He has extensively published in the fields of political and legal philosophy, as well as on constitutional and international law theory. Amongst his most recent publications is the book “Paradigms of Social Order” (Palgrave Macmillan 2021) in which he explores the evolution of the concept of order from the antiquity to the present days. He is presently authoring a book entitled ‘A Republic of Fellow Sufferers: How to Grant Rights to Nature’, in which he analyses different strategies to justify the attribution of rights to non-human natural entities. During his stay at Durham Law School, he will carry out research on whether a revised recognition-based theory of rights can be applied to sentient non-human animals as well as on the consequences this might have regarding both the understanding of the possible foundation of rights and the project of extending moral and legal entitlements to non-human components of the natural world. In addition, Dellavalle will analyse and discuss the impact that the most recent events in international relations might have had on the idea of order in the national and international context.
