Eller holds law degrees from the University of Cologne and Université de Paris 1 (Panthéon-Sorbonne), passed the bar exam at the High Court of Berlin and is presently a PhD Fellow at Humboldt-University’s European Law School in Berlin as well as a Research Assistant at the Chair for Private Law and Legal Theory in Cologne. He has held previous visiting positions at the École des Hautes Études en Sciences Sociales (Paris) and the Edmond J. Safra Center for Ethics, Tel Aviv University. Since 2014 Eller is part of the Institute for Global Law and Policy at Harvard Law School’s multidisciplinary Law and Global Production Working Group. His practical experience includes clerkship positions at the Supreme Court of the State of Israel and the International Criminal Tribunal for former Yugoslavia (ICTY) as well as positions with an international arbitration boutique and the German Ministry of Economic Affairs.

Eller's research interests are centered around the role of (private) law in social and technological change, particularly through an angle of contract and competition law, as well as business and human rights, socio-legal theory and the history of legal thought. His PhD deals with the legal form and blind spots of global value chain capitalism.

Research at TraffLab:  Eller will research the politics of transparency regulation in global value chains, especially with regard to forced labor. To this end, transparency requirements along value chains are understood as a specific form of knowledge production which not only discloses, but is itself transformative with regard to the legal design of a chain.
