How does the brain control access to conscious awareness? Of the multitude of information available to us for processing at any given moment, both in our external sensory and internal representational environments, only a small subset receives this privilege. Selective attention broadly describes the many neural processes that give rise to this ‘filter’, which enables us to quickly locate an oncoming cyclist when crossing a busy street, or tune out competing voices while conversing with a friend at a crowded dinner party.

In the laboratory, we often treat attention as operating in a vacuum. In real life however, attention often has potent interactions with memory. My research focuses on the neural basis of this interaction, and how it is altered by aging and neuropathology. To address these questions, I use an array of in vivo neuroimaging techniques, including magnetic resonance imaging and scalp electroencephalography.
