Since December 2025, Jens Althoff has headed the Heinrich Böll Foundation's Regional Office in Warsaw, which operates in Poland as well as in Lithuania, Latvia, and Estonia.

Jens Althoff joined the Heinrich Böll Foundation in 2015, where he established a new office in Paris and led it from 2015 to 2021. Under his leadership, the Paris office became a key actor in the fields of ecological transformation, the strengthening of democracies in Europe, foreign and security policy, and European policy in France. Beginning in 2019, the office expanded its work on these thematic areas to Italy as well. During this period, he advanced numerous projects within the foundation under the "Weimar Triangle" framework and collaborated closely with the Heinrich Böll Foundation's office in Warsaw.

From early 2022 until the summer of 2025, Jens Althoff served as Head of Communications and Spokesperson for the Minister of State for Culture and Media, Claudia Roth, in the Federal Chancellery, in Germany. In this role, he worked on all matters related to cultural and media policy, including remembrance policy, both in a European framework and, in particular, within the Polish-German context. An important part of his work for the German government was supporting Ukrainian culture in both Germany and Ukraine.

Before joining the Heinrich Böll Foundation, he worked in the European Parliament, concentrating primarily on issues of European foreign and security policy. He also served for eight years as Head of the Press Office and Spokesperson for the Federal Executive Committee of the German Green Party.

While studying political science, rhetoric, and public law at the University of Tübingen, as well as political and social science at the Sciences Po in Paris, he worked as a journalist for various local and regional media outlets. During this period, he also served as a research assistant at the Center for Journalism at the Free University of Berlin, where he organized advanced training programs for professional journalists. Among other initiatives, he established a journalist exchange program for participants from Ukraine, Belarus, and Russia in 2000.

Over the same period, he completed his doctorate in political science, focusing on the role of credibility and trust in political communication and voter behaviour.

Jens Althoff is a committed European for whom work is not merely a profession, but a vocation.
