My research interests include vulnerability scans, secure software development, the analysis of mobile applications for Android and iOS, as well as web & network security. In my Ph.D., I focused on new analysis strategies to pinpoint the exact origin of problematic code and innovative methods to enable a more profound understanding of what functionality is actually executed within mobile applications.


I teach networks as part of several undergraduate courses:
  • Computer Organization and Networks – lecture and practicals: winter term
  • Information Security – lecture and practicals: winter term
  • Rechner- und Kommunikationsnetze – lecture and practicals: winter term
In a graduate course, I highlight security aspects of smartphones and mobile applications:
  • Mobile Security (Advanced Computer Networks) – lecture and practicals: summer term
