About me

I am Junior Research Group Leader of the Young Investigator Group ”COSYS - Control Systems and Cyber Security Lab” at the Chair of IT Security. Before, I was a postdoctoral researcher at the University of Luxembourg in the Applied Security and Information Assurance Group (APSIA) at the Interdisciplinary Centre for Security, Reliability and Trust (SnT). I did my PhD at Saarland University, thesis title “Cryptography with Anonymity in Mind”.

Research Interests

I am interested in intrusion detection systems (IDS) for critical infrastructures, secure cyber-physical systems, artificial intelligence / machine learning for traffic analysis, honeypots, privacy enhancing techniques, cryptography, and voting algorithms.

Projects

The interdisciplinary COSYS-Lab is a part of the EIC project and focuses on developing optimal operating strategies for multi-energy systems and cyber-security aspects in digitally networked energy systems. Together with colleagues from the COSYS-lab, I am currently involved in setting up the Hardware-in-the-Loop (HiL) laboratory and in a project on artificial intelligence (AI)-based network attack detection. Setting up the HiL lab will help us to create a realistic environment and datasets useful for conducting research.

The cyber-security scope of the EIC project covers a wide range of topics, such AI-based network attack detection and simulation, AI-enabled penetration testing, and privacy-enhancing technologies in cyber-physical systems.
