Research

In order to interact with the world, our brains construct and sustain their own internal representations of it. Our aim is to understand the nature of these representations and the computations the brain performs on them to achieve behavioural goals. In the lab, we use visual psychophysics and memory tasks, eye and limb movement recordings, mathematical models and computer simulations. We also collaborate with researchers using brain imaging, recording and stimulation, and with neuropsychologists who study cognitive aging, mental illness and neurological disorders.
