Field of Research

Colour is a fundamental aspect of our visual experience and enables us to recognize objects fast and reliably. Traditionally, colour research has focused on colour as an isolated visual feature. However, it is now apparent that chromatic information also facilitates a multitude of other visual tasks and is available in many visual areas in the cortex.

In our basic research we aim to understand the functional organization of  colour processes and their interactions with other submodalities (e.g. form, depth and motion), sensory, perceptual and cognitive processes involved in colour constancy, and the role of colour in guiding actions. In clinical research we study the effects of ageing on visual functions, visual deficiencies associated with dyslexia, and the perceptual consequences of inherited retinal dysfunctions (congenital stationary night blindness). In cooperation with the Faculty of Biology we also investigate colour vision in an animal model, the honeybee Apis mellifera. The results of our research are applicable in robotics e.g. for the development of artificial visual systems, as well as for medical advances in visual prostheses.
