Research Description
My work is focused on understanding attention, both how it works and how it fails, mostly in the visual domain. I have studied issues such as temporal attention, why we tend to get distracted when we concentrate over long periods of time, how we tune out the world when we are trying to concentrate, and how it is that we find objects in a scene.
