Cathleen Berger is a self-starter with 15+ years of professional experience at the intersection of tech policy, change management, and environmental sustainability. She has worked across sectors and with globally distributed teams in academia, government, non-profit, corporate, and now parliament. She brings structure to complex challenges, thrives in collaborative and impact-focused environments, and often finds herself driving processes for improving organisational culture, sustainability, and political direction.

In July 2025, she joined the German parliament as head of office for research and policy for the Deputy Chair on the Digital Committee. Before that, she worked with the Bertelsmann Stiftung as Co-Team Lead for Upgrade Democracy and Research Director on future technologies and sustainabilty.

In earlier roles, she launched and headed up Mozilla‘s environmental sustainability programme, for which she set strategy for Corporation and Foundation, oversaw data collection, analysis, and visualisation for Mozilla‘s Greenhouse Gas emissions (GHG assessment), planned for mitigation, set and implemented company-wide emissions reduction targets, and recruited, trained, and worked with organisational change agents, Mozilla’s environmental champions. Prior to that, Cathleen led Mozilla’s work on Global Governance, where she represented Mozilla at fora such as the G20, the United Nations, or the World Economic Forum and developed policy and impact strategy for the Office of the Chair.

Other experiences include policy strategist with the International Cyber Policy Coordination Staff at the German Foreign Office, consultant with Climatiq, Liberate Science, and Global Partners Digital, research assistant at the German Institute for International and Security Affairs (SWP), and visiting lecturer at the Friedrich Schiller University Jena.

In addition, she has held voluntary roles as a fellow at the Centre for Internet and Human Rights (CIHR), a Global Governance Futures fellow at the Global Public Policy Institute (GPPi), an associate at Stiftung Neue Verantwortung (snv) contributing to research as an expert on encryption and strategic foresight, a mentor for feminist tech fellows at the Superrr Lab, an expert on the interplay of technology and sustainability in the World Economic Forum‘s Global Future Council, as well as a Raisina Young Fellow at the Asian Forum on Global Governance.
