Klaas Hendrik Eller is Associate Professor of Private Law at the Amsterdam Center for Transformative Private Law (ACT) and affiliated with the Sustainable Global Economic Law (SGEL) research project. 

His research examines how (private) law shapes the organisation of the global economy and its ongoing transformations — ecological, digital and geopolitical. A key strand of his work centers on the legal architecture of global value chains, tracing how contract, corporate accountability and EU regulation structure global production: from sustainability due diligence legislation (CSDDD, EUDR) and the digital compliance infrastructures emerging around it, to pricing, logistics, supply chain resilience and the temporal and geoeconomic ordering of global commerce. A second strand of his work concerns housing and global cities, including tenancy law, financialisation and the right to housing. Methodologically, his scholarship combines private law theory with socio-legal and ethnographic approaches, law & political economy, and the history of legal thought. He is currently working on a project funded by a Veni grant by the Netherlands Organisation for Scientific Research (NWO) titled 'Recoding Global Production: Towards a Legal Ethnography of Sustainable Global Supply Chains' and serves as the co-PI to the projects 'Digital Infrastructures of Sustainability Regulation (DigiChain)' and 'Data Infrastructures of Deforestation Governance' (DATAFOREST). 

Klaas is a co-editor-in-chief of the German Law Journal, and editor of Kritische Justiz, and a member of the Amsterdam Young Academy (AYA). Based on his academic work, he has served as expert or consultant to international organisations, national governments and civil society organisations, is involved in executive education, and his commentary has appeared in different media outlets.

Klaas obtained his PhD from the University of Cologne ('The Constitution of Global Production', summa cum laude, Faculty Prize) and holds law degrees from Cologne and the Université de Paris 1 (Panthéon-Sorbonne). Klaas passed the German bar exam (Referendariat) at the High Court of Berlin with secondments inter alia at the Supreme Court of the State of Israel (Justice Daphne Barak-Erez) and an international arbitration boutique. He was a Doctoral Fellow at Humboldt-University’s European Law School Graduate Program, held fellowships at both Tel Aviv University's and Harvard University's Safra Center for Ethics, was a Visiting Researcher at the Institute for Global Law and Policy (IGLP, Harvard Law School) and a Visiting Professor at Copenhagen Business School (CBS), Tel Aviv University and LUISS University (Rome). 

At the UvA, Klaas serves as the Program Director of the Transnational and European Private Law LLM and as Academic co-Coordinator of the "European Law School". His teaching portfolio of recent years includes European Contract Law (MA), Comparative Law (MA), Private International Law (MA), Research Training Seminar in European Private Law (MA), Making Markets Beyond the State (MA), European Private International Law (MA), Principles in European Contract Law (BA PPLE), and Moot Court in European Union Law (BA).
