Dr Leonelli is Assistant Professor of Law in the LSE Law School. She researches and teaches in the fields of climate change law, environmental law, trade law, and risk regulation. Dr Leonelli’s current research projects lie at the intersection of trade and climate change law, with a particular focus on the path towards net-zero and new forms of environmental unilateralism and plurilateralism. Her latest publications provide a conceptually informed insight into trade-related measures that are designed to produce specific environmental effects.

Dr Leonelli’s research on carbon border measures and climate clubs has fed into policy discussions regarding the G7 blueprint for climate club arrangements. She regularly contributes evidence to inquiries of the House of Commons Business and Trade Committee, the House of Lords International Agreements Committee, and the UK Government. In October 2023, she was invited to give oral evidence to the House of Lords International Agreements Committee regarding the UK accession to the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) and its implications for UK levels of food safety and environmental protection.


Prior to joining LSE, Dr Leonelli was Lecturer in Law at Birkbeck, University of London, and Postdoctoral Research Fellow at the Transnational Law Institute, King’s College London. She holds a PhD in Law and an LLM (Distinction) from King’s College London. Her PhD thesis won the Elsevier Prize for Outstanding Doctoral Work in 2018. It was published as a monograph in 2021 (Transnational Narratives and Regulation of GMO Risks, Hart Publishing).
