Current Research

I am a postdoctoral fellow at the University of Duisburg-Essen working on areas of privacy and cybersecurity. My main research focus is human-computer interaction with special attention to privacy decision-making processes in social network sites. Particularly, I am interested in digital nudging applications to cybersecurity, their personalization through Artificial Intelligence (AI), and ethical issues arising from combining persuasion together with AI. Since, August 2018, I am a member of the H2020 project “PDP4E: Methods and Tools for GDPR Compliance through Privacy and Data Protection Engineering” and since January 2020 the coordinator of the RTG “User-Centered Social Media”.
My research interests and areas of expertise are among others:

  • Human-computer Interaction
  • Software Engineering
  • Artificial Intelligence
  • Machine Learning
  • Privacy and Cybersecurity
  • Internet governance
  • Public policy development
