Biography

Since March 2019, I’m a researcher and Ph.D. Student at Klaus Wehrle’s Chair of Communication and Distributed Systems at RWTH Aachen University. Currently, I’m dedicated to scrutinizing the security of industrial deployments, identifying the roots of insecure configurations, and devising mechanisms to improve the level of security. I also research mechanisms for secure communication in the ICT network of critical infrastructures. Before starting my Ph.D. studies, I graduated with an M.Sc. in Computer Science in September 2018 and received my B.Sc. in 2016. During my Bachelor’s and Master’s studies I, amongst others, got in touch with kernel-programming and anonymous communication via Tor.
