I am a PhD student in the Social Cognitive Systems Group at CITEC, Faculty of Technology at Bielefeld University headed by Prof. Dr.-Ing. Stefan Kopp.

In the VIVA project we aim to build a mobile social robot that produces lively and socially appropriate behavior in interaction.
My research interest lies in endowing the robot with basic dialogue capacities and further, the ability to explain its behavior in a way that is intuitively understandable by the user. The long-term prospective is to enable the user to evaluate the robot's behaviors based on the offered behavior explanation and decide on the appropriateness. The user should thus be given the opportunity to educate the robot according to their own preferences.
