About Me

Since January 2022, I am a PhD student at the Chair for Information Security. Before that, I worked as a research assistant at the Chair for Embedded Security at the Ruhr University Bochum and as a visiting researcher at the Embedded Security group of the Max Planck Institute for Security and Privacy. I obtained both my Bachelor’s and Master’s degree at the Ruhr University Bochum in cybersecurity with a focus on wireless physical layer security. 



My research focuses on the impact and robustness of machine learning systems. This includes but is not limited to MLaaS deployments, distributed and decentralized learning systems, e.g., federated learning, and real-world deployments, such as autonomous vehicles or facial recognition systems.
