My laboratory researches the mechanisms and machinery underlying healthy brain functions and the cognitive deficits that emerge as a result of brain disease and advanced aging.
Understanding Brain Function and Dysfunction
To this end, we study patients suffering from neurological conditions (such as stroke and Parkinson's disease), as well as neurologically healthy young and aging adults. We then combine the knowledge gained from each of these groups so that we can advance the current understanding of brain function and brain dysfunction.
Visual Orienting
My main interest is in visual orienting, including attention and eye movements, with a particular focus on how more advanced brain structures orchestrate the activities of more primitive brain structures in order to generate strategic behaviours.
