Christian Killer

Christian Killer joined the Communication Systems Group (CSG) in February 2019 to obtain his doctoral degree under the supervision of Prof. Dr. Burkhard Stiller. He finished his Master’s Degree in Informatics at the University of Zurich, focussing on Security Management and Visualization in a Blockchain-based Collaborative Defense. During his Master’s, he also completed a Master’s Project Provotum - Privacy, Verifiability, and Auditability in Blockchain-based E-Voting which evolved in multiple versions and spun off to additional voting systems as well.
