Curriculum Vitae
I would like to understand how embodied and situated nervous systems develop cognition. To do that, my colleagues and I have developed the theoretical framework of Dynamical Field Theory. In a set of close theory-experiment collaborations we validate the concept of the theory and systematically build an account of action, perception, and embodied cognition. Exemplary studies include multi-degree of freedom movements, learning of motor skills, perception of motion, working memory for action, space and visual features, sensory-motor decision making and the development of early cognition and motor behavior. In a second line of research we develop of autonomous robots inspired by these same theoretical principles. The main emphasis is on service robotics, in which autonomous robots interact with human users.

I also teach as a professor, and am the director of the Institute, and have all kinds of other obligations.
