Research Projects


The "Digital Twin-4-Multiphysics Lab" (DT4MP) focuses on urban digital twins (UDTs) and multiphysics twins for industry, treating both areas equally and synergistically. By integrating real-time data and advanced simulations, DT4MP enhances urban processes, infrastructures, and industrial production efficiency. Combining AI and machine learning, the lab provides services like data analysis and virtual testing for SMEs and larger companies. Founded by leading institutes, DT4MP drives digitalization research in urban and industrial contexts.

Cyber Security Learning Lab - High-security and emergency response

Information and communication technologies (ICT) have become part of our everyday life and it is almost impossible to imagine life without them. Reason for that is the increasing digitalization of our world. Especially in our economic sector ICTs are one of the most driving factors for innovation and therefore strongly responsible forthe competitiveness of many companies. But ICTs not only influence our lives within economy, they also shape our society e.g. in authorities.
