My research mainly concerns the neural mechanisms that underlie selective attention and perception in humans. Because far more information is present in the environment than can be fully processed by the brain, and because behavioral responses need to be controlled by events that are relevant to our goals, selection mechanisms play a fundamental role in human perception and action. Accordingly, attending to a stimulus strongly modulates the neural response to that stimulus in many brain regions. I use neuroimaging methodologies, such as functional magnetic resonance imaging, to study the nature and function of these modulations. A second line of research uses our knowledge of attention in healthy adults to understand the attentional dysfunctions that are often observed following strokes. A recent development is the use of resting-state measures of brain activity to characterize how strokes change the brain networks that underlie attention.
