PD Dr. iur., MA Charlotte Sieber-Gasser

Charlotte Sieber-Gasser is a legal scholar working at the intersection of constitutional law, international economic law, public international law and European law, and a Fellow of the World Trade Institute (WTI), University of Bern. Her research centres on the internationalisation of law: Combining doctrinal legal analysis with empirical methods and legal theory, she investigates how domestic, European and international legal orders interact in addressing common concerns of humankind and explores the implications of these developments for democracy and global justice.

Charlotte's research broadens the traditional focus of international economic law towards the constitutional implications of global interdependence. She is the author of the award-winning monograph Developing Countries and Preferential Services Trade (Cambridge University Press, 2016) and the monograph Die Internationalisierung des Rechts in der Schweiz: Demokratie auf der Streckbank (Mohr Siebeck, Open Access, 2026), which offers the first comprehensive legal analysis of the internationalisation of law in Switzerland. Her wider body of work explores the various legal implications of globalisation, including sustainable trade, regulatory complexity, economic coercion, the democratic implications of the EU–Swiss bilateral agreements, and the universally recognised essential core of sustainable development.

Beyond her individual scholarship, Charlotte has extensive experience in designing and leading interdisciplinary research. She has held senior roles in major Swiss National Science Foundation projects, including the NCCR International Trade Regulation and the Sinergia project Making Trade Agreements Work in the Service of Society, where she coordinated research at the interface of law, economics and political science. As academic co-founder of Besso, she contributes to applied research that bridges legal scholarship, machine learning and business practice.

Charlotte maintains an extensive international academic and professional network and contributes to scholarly exchange, policy dialogue, public debate and institution-building within the legal community. She regularly collaborates across disciplines and sectors, serves in advisory and governance roles for academic and public-interest organisations, and fosters dialogue between academia, policy and practice through collaborative research, mentoring and public engagement.
