Jonathan Liebers

Academic Career and Research Areas:

Jonathan Liebers holds a B.Sc. and an M.Sc. in Applied Computer Science – Systems Engineering, as well as a doctorate in Human-Computer Interaction from the University of Duisburg-Essen. In March 2026, he joined the Human-AI Interaction group at RC Trust as a postdoctoral researcher. His research lies at the intersection of human-computer interaction, machine learning, and extended reality, with a focus on intelligent, human-centered systems. He is particularly interested in how human behavior can enable seamless and secure user interactions, and how the potential of Agentic AI can transform security-related interactions to make them helpful and friendly to the user.
