Christian Stein studied German and Computer Science, received his doctorate in Literature and has since been active at the interface of the humanities and technical sciences.

At the cluster of excellence 'Image Knowledge Gestaltung' (Humboldt University Berlin) he was leader of the project Architectures of Knowledge and co-founder of gamelab.berlin, which deals with the game as a cultural technique. In this context, he has focused on the development of game prototypes and VR applications for exhibitions and medical contexts.

In addition, Christian Stein deals with artificial and natural languages as well as an interdisciplinary theory of the interface, to which he is currently completing his habilitation project. At Matters of Activity in the project Object Space Agency he is working on the conception and implementation of forms of interaction which are intended to make objects and people both active and experienceable in a new way.

His other fields of research are big data, data privacy, model theory, space theory, semantic web, semiotics and terminology.
