Our Mission

The Center for Advanced Security, Strategic and Integration Studies (CASSIS) is an interdisciplinary research center at the Rheinische Friedrich-Wilhelms-Universität Bonn in the field of strategic foresight, European and security policy research. Committed to the approach "Global Challenges Need European Responses", CASSIS contributes in interdisciplinary and inter-institutional work to develop, evaluate and publicly discuss European strategies to current challenges in the field of foreign and security policy. 

Our Partners

Since 2019, CASSIS has developed into an important platform for the transfer of academic expertise and knowledge on pressing strategic topics both to the academic and non-academic audiences through a range of our research and high-profile teaching and event formats. While doing so, we were able to receive invaluable support from our great partners. CASSIS is very grateful to their support and we are proud to be well connected to many wonderful institutions. Together with our valued and trusted partners, we are able to foster discussions on matters of strategic importance near and abroad and jointly conduct and advance important research projects.

The International Security Forum Bonn 2023

From 19 October to 22 October 2023, ISFB will be held for the eighth time in person on the premises of the University of Excellence Bonn as the most important international security conference in North Rhine-Westphalia and all neighboring federal states.


Our Focus

The content focus of CASSIS is, on the one hand, on the interdisciplinary engagement with traditional foreign and security policy topics such as interstate conflicts, competing international order systems, and a return of geopolitics, and on the other hand, on non-traditional security challenges related to space, cyber, climate, and energy security, terrorism, and human security.

Prof. Dr. Ulrich Schlie at TRT Global: As Merz gets set for Trump meeting
Prof. Dr. Ulrich Schlie, Henry Kissinger Professor for Security and Strategic Studies at the University of Bonn, sees Chancellor Merz’s trip to Washington as an opportunity—only if substance follows symbolism and Europe steps up security commitments.

Ali Fathollah-Nejad on KAS online: U.S.–Iran Talks Reach Critical Stage
Negotiations between the United States and the Islamic Republic of Iran have reached a turning point. While Washington's position continues to evolve, Tehran remains largely unwilling to make concessions. With the next round of talks approaching, a resolution remains elusive.
Prof. Dr. Ulrich Schlie on the NATO meeting in April 2025 on WDR
Following Donald Trump's re-election, transatlantic cooperation faces its greatest test yet. In an interview with WDR, Prof. Ulrich Schlie warns that Europe can no longer rely on the US. NATO is under pressure – now Germany must show strategic backbone and take responsibility.
Germany between a warning and destabilization – Prof. Dr. Ulrich Schlie on the chancellor election
Prof. Ulrich Schlie sees Friedrich Merz's botched first round of voting as a serious warning signal, but not a national crisis. The behavior of individual MPs was “highly dangerous” and undermined the stability of the new government. The old political comfort is over - in future, politics must act in uncertainty and strategic trust between the parties must be rebuilt.

Current Scientific Publications
Global structures of digital dependence and the rise of technopoles
In their article published in New Political Economy, Maximilian Mayer and Yen-Chi Lu examine global patterns of digital dependency, highlighting how the United States and China, as key “technopoles,” possess significant technological sovereignty and strategically use digital infrastructures as instruments of power. Using the Digital Dependence Index (DDI), they develop a conceptual and data-driven model that reveals dependency structures across the areas of hardware, platforms, and patents. Theoretically, the study draws on approaches from international relations, international political economy, and concepts of structural dependency to analyze the geopolitical implications of digital asymmetries.
Connectivity and ‘Reglobalization’: India-Middle East-Europe Economic Corridor and its Potential Digital Future
Dr. Gedaliah Afterman, Dr. N. Janardhan, Mohammed Baharoon & Dr. Maximilian Mayer argue that the India-Middle East-Europe Economic Corridor (IMEC) remains a strategic opportunity for driving economic growth, promoting technological collaboration, and serving as a platform for regional stabilization. The authors also stress that such initiatives have the potential to bolster middle powers and an inter- and trans-regional approach, thus mitigating U.S.-China bipolarism and fragmentation.
Publication of the Report by CASSIS of the University of Bonn and the EWI of the University of Cologne
Hydrogen is considered an important part of the EU's and Germany's climate neutrality strategy. Significant progress is required for the ramp-up, otherwise the targets might not be met. A report by CASSIS and EWI analyses the status of the ramp-up.
After NATO — the way forward
Emilian Kavalski and Maximilian Mayer write about the growing rift between Europe and the United States, drawing parallels between Winston Churchill’s contradictory views on America and the current strategic dilemmas facing Europe. While publicly advocating for a strong Anglo-American alliance, Churchill privately viewed the U.S. as an unreliable and self-interested partner—an argument that resonates today as the Trump administration actively undermines European security. In response, the authors call for Europe to pursue an independent defense strategy, moving away from reliance on the U.S. and toward a new security architecture.
Election campaign in focus: Disinformation and the Bundestag election 2025
The upcoming Bundestag election is threatened by foreign disinformation campaigns aimed at undermining trust in the democratic process. Russia, in particular, is relying on manipulated content and targeted influence on public opinion. Security authorities are responding with various measures to counter this threat.
Enhancing European Space Access: Fostering Innovation Ecosystems to Strengthen EU Space Capabilities
The relevance of the space sector will continue to increase in the future. Against the backdrop of the current geopolitical power shifts, the EU faces the challenge of developing a sustainable and robust strategy for the development of its own space capabilities. In the new CASSIS Policy Paper, Ulrich Schlie, Gregory Tutton and Philip Schäfer analyze the EU's strategic position in space and provide suggestions and impulses for improving Europe's space capabilities.
Follow-Up: Global Health in Crisis
Maximilian Schranner highlights the U.S. withdrawal from the World Health Organization (WHO) under Donald Trump, which represents less an unexpected break and more a continuation of the ongoing weakening of international health structures. In light of this development, the new federal government must acknowledge these new realities and work with international partners to establish a minimal global health protection framework.
U.S.-China Digital Fragmentation Is Putting the World in a Bind
Laura Mahrenbach and Maximilian Mayer write about the increasing digital fragmentation driven by regulation and national interests in major tech powers such as the U.S., China and the EU. To address the challenges and risks, they argue that countries should adopt a strategy of pragmatic resilience combined with cooperative approaches.
