Service-centric Networking

Prof. Dr. Axel Küpper

Scientific Career

Axel Küpper is a professor for Service-centric Networking at Technische Universität Berlin (TU Berlin) and Telekom Innovation Laboratories, which is a public-private partnership of Deutsche Telekom AG and TU Berlin.

Before, he was an assistant professor at the Mobile and Distributed Systems Group at Ludwig-Maximilians-Universität München, where he received his postdoctoral lecture qualification (habilitation). He graduated in computer science from RWTH Aachen University, where he also received his doctorate.

Axel's early research focused on distributed and mobile systems and networks, context-aware applications, and location-based services. In recent years, he has worked intensively on topics related to Cloud Computing, Service-oriented Architectures, and future web technologies. Axel is an advocate of decentralized systems and applications. The focus of his work here is on distributed ledger technologies, token economy, self-sovereign identity, emerging blockchain-based applications, blockchain analytics, and decentralized online social networks.
