Personal Information

After graduating from Karlsruhe Institute of Technology with a Master's degree in Computer Science, I work since February 2018 with the research group "Decentralized Systems and Network Services" of Prof. Hartenstein at the Institute of Telematics. Currently I work on methods for topology inference in peer-to-peer networks at the example of Bitcoin as well as payment channel networks as an idea to solve the problem of scaling crypto currencies such as Bitcoin.
