Stefan Valentin (ORCID) is Professor for Mobile Networks and Foundations of Computer Science at the Darmstadt University of Applied Sciences. He is interested in resource allocation and load balancing for mobile networks, based on methods from mathematical optimization and machine learning. Stefan’s algorithms are deployed in base stations around the world and more than 30 patent applications have been filed for them. He co-authored more than 100 peer-reviewed research papers, which have been cited about 2000 times and have received 4 awards. Stefan is a member of the IEEE and consulted BMBF and BMWi on 5G, Internet-of-Things (IoT) and Industry 4.0.
