Boris Otto is the Executive Director of the Fraunhofer Institute for Software and Systems Engineering ISST in Dortmund as well as Chair for Industrial Information Management at TU Dortmund. His career path includes the University of St. Gallen, PricewaterhouseCoopers, SAP, and the Fraunhofer Institute for Industrial Engineering IAO. He is a member of the boards of directors of the Gaia-X, European Association for Data and Cloud, AISBL and the International Data Spaces Association (IDSA). His research focuses on the fields of industrial information management, business and logistics networks, and methods for the design of digital business solutions.Michael ten Hompel holds the Chair of Materials Handling and Warehousing at TU Dortmund and is Managing Director at Fraunhofer-Institute of Material Flow and Logistics IML. Besides his work as scientist, he also worked as entrepreneur and eg founded GamBit GmbH in Dortmund in 1988 and is still on the supervisory board of several logistics companies. He was also awarded the Innovationspreis NRW (Innovation Award North Rhine-Westphalia) in 2020.Stefan Wrobel is Professor of Computer Science at U Bonn and Director of the Fraunhofer Institute for Intelligent Analysis and Information Systems IAIS. His work is focused on questions of the digital revolution, in particular intelligent algorithms and systems for the large-scale analysis of data and the influence of Big Data/Smart Data on the use of information in companies and society. He was honored by the Gesellschaft für Informatik (German Informatics Society) as one of the formative minds in German AI history.
