About CASA

The Cluster of Excellence CASA conducts research on sustainable computer security against powerful, large-scale attackers, in particular nation-states. The Cluster is funded by the German Research Foundation (DFG) within the Excellence Strategy of the Federal Government and the Länder. The funding of 30 million euros allows us to lend excellent support to the needs and ambitions of upcoming scientists.

Research at CASA, which is based at the Horst Görtz Institute for IT Security, follows a strongly interdisciplinary approach. In addition to technical questions, it also investigates the interaction of human behavior and IT security. At CASA, researchers from the fields of computer science, cryptography, electrical engineering, mathematics, and psychology work together in a unique constellation in Europe. This holistic approach is unparalleled and holds the potential for scientific breakthroughs.

Research environment

Ruhr-University Bochum (RUB) and its Faculty of Computer Science offer an excellent environment for aspiring young researchers. Some 20 years ago, the Horst Görtz Institute for IT Security (HGI) was founded here. It is now one of Europe's most prestigious institutions for basic computer security research. The HGI maintains extensive networks with leading research institutions worldwide asnd with media and industry. Moreover, it has produced numerous successful security startups. The pioneering work of the HGI forms the basis for the Cluster of Excellence CASA.

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.


The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
