hanna-siteI am Hanna Schraffenberger — a creative researcher studying digital sovereignty and autonomy from a human-centered perspective. In particular, I focus on privacy- and security-enhancing technologies, online manipulation, and AI-supported decision-making.

I conduct playful hands-on research where the human-centered design of proof of concepts and interactive artifacts plays a central role in identifying questions and obtaining knowledge. I employ a critical, constructive, and creative perspective toward digitalization and aim to develop software that puts public values central. I am passionate about education and teach courses on human-centered security and AI, as well as requirements engineering and design. I care about diversity in ICT, and strongly believe in interdisciplinary research and team science.

I am an assistant professor at Radboud University’s Digital Security group and am affiliated with Radboud’s interdisciplinary research hub on digitalization and society (iHub).
