I am currently a lecturer and researcher at DISCO. Until 2018, I was a PhD student supervised by Prof. Dr.-Ing. Jens B. Schmitt. Before that, I worked for the Information Technology and Cyberspace group of armasuisse S+T and visited the University of Oxford (hosted by Prof. Ivan Martinovic) in 2012. I am also a co-founder of the OpenSky Network association and managing director of SeRo Systems GmbH.
