I am Professor of Psychology at University of Aberdeen, UK. Originally, I trained as an Electrical and Electronic Engineer, but soon got interested in behaviour of monkeys and then human behaviour. In particular, I have been fascinated by the way we code and process sensory signals and use this internal representation to interact with our environment. By studying healthy adults as well as individuals with damaged/lesioned brain, we can slowly unravel how the representations of the external world are formed by our nervous system, learned/reinforced and then used to make decisions in our interactions. I have mostly studied vision and more recently its interaction with auditory system and how both are modulated by other psychological states.
