Jannika Jahn is a Senior Research Fellow at the Max Planck Institute for Comparative Public Law and International Law in Heidelberg, where she has been working since 2020. She also serves as an Associate Fellow at Maastricht University's Globalization and Law Network and as Associate Editor at Verfassungsblog for International Law and Human Rights Protection. Her work focuses on the intersection of international law, human rights, and environmental protection, with particular expertise in business and human rights law and climate litigation. Jannika Jahn received her LL.B. in English and German Law from University College London and the University of Cologne, where she completed her first state's exam. She earned her doctorate (summa cum laude) from the University of Heidelberg with a dissertation on "The media publicity of the judiciary and its limits." Her doctoral work was conducted at the Max Planck Institute for Comparative Law and Public International Law. Jahn's research spans European and international human rights law, business and human rights law, international environmental law (particularly climate law), comparative constitutional law and theory, and interdisciplinary legal analysis. She examines how national courts can serve as guarantors of global climate protection and investigates the role of judicial independence in multi-level governance systems. Her work on supply chain regulation explores how to create effective human rights due diligence frameworks for multinational corporations. Her scholarly output demonstrates a clear trajectory from foundational work on judicial independence and media coverage of courts toward increasingly focused research on climate litigation and business and human rights. Recent publications highlight her expertise in analyzing how constitutional courts worldwide are becoming key actors in climate governance and how supply chain legislation can be designed to effectively protect human rights across global value chains. Jahn has received several prestigious honors for her academic work, including: Ruprecht-Karls-Preis awarded by the Stiftung Universität Heidelberg for the best legal doctoral thesis in 2020 Scholarship for the doctoral thesis by Friedrich-Ebert-Stiftung Scholarship for law studies by Studienstiftung des Deutschen Volkes Scholarship for LL.B. studies by Alexander-Lüderitz-Stiftung As a Senior Research Fellow, Jahn leads her habilitation project and a business and human rights project at the Max Planck Institute. She has served as a legal expert for the Consultative Council of European Judges (CCJE) of the Council of Europe regarding judicial independence and freedom of expression of judges. Her advisory work extends to policy development, as evidenced by her contributions to the German Supply Chain Act. She regularly presents her research at international conferences and teaches courses on European human rights protection, climate change challenges, and comparative constitutional law. At the Max Planck Institute, Jahn is actively involved in research teams focused on business and human rights and climate litigation. She participates in the Institute's Gender Equality initiatives as the Gender Equality Officer and contributes to interdisciplinary discussions on current challenges in international law through the Institute's research colloquia and workshops.
