About Us

Mission & People

The HGI, Research Department of the Ruhr-Universität Bochum (RUB), is one of the largest and oldest institutes in the field of IT security in Europe. The institute was founded in 2002 at RUB to address the Europe-wide deficits in public research on IT security.

Currently, around 160 scientists from computer science, electrical engineering, information technology and mathematics as well as the humanities and social sciences are conducting research at the Research Department IT Security.

Our research is driven by these goals and values:

Our Mission Statement

At HGI, we aim

to conduct pioneering and cutting-edge research and lay the foundations for future cyber security
to provide excellent teaching and job opportunities for young cyber security researchers
to protect the general public, developers and users of cyber security alike
to make results available to the general public and maximize societal benefit of research
to be an important mediator in communication and in creating awareness for cyber security
to be a leader in the transfer of knowledge and in creating startups

Working Group SicherDigi

SicherDigi (Security Production in the Digital Age) is an interdisciplinary research group that explores the topic of IT security from the perspective of the humanities and social sciences in close exchange with the technical sciences. SicherDigi investigates dynamics and processes of change at the intersection of the analog and the digital with a view to the question of how a need for IT security arises and what desired and unintended effects result from guaranteeing it. One focus is on empirical examples with a regional reference to the Ruhr region, which are used to concretize global developments. Both producers and consumers of IT security are taken into account. SicherDigi currently brings together RUB researchers from media science (Tuschling), philosophy (Weydner-Volkmann), law and criminology (Golla), social science (Sørensen, Galanova) and contemporary history (Goschler, Böick, Kirchberg).

SFB 1567

The Collaborative Research Center (SFB) 1567 "Virtual Lifeworlds" is an interdisciplinary network that researches the increase of virtuality in everyday life and the social and cultural transformation processes it sets in motion. It is dedicated to the virtual infusion of social subsystems and asks for consequences of individual subjects and their constitution, of lifeworld and aesthetic practices as well as social organizations and operations. The SFB gathers researchers from educational studies, German studies, history, art history, media studies and social sciences.
