My current research interests are in perception and attention broadly, with an emphasis on the mechanisms of visual perception, visual attention, and working-memory. More specifically, I am interested in interactions between early, low-level perceptual processing and later, high-level processes such as attention, working-memory, and action execution. In another line of research, I am part of a project attempting to develop in-vehicle collision avoidance systems for individuals with impaired attention abilities due to aging, brain damage, and neurological diseases such as Parkinson's and Alzheimer's. I employ primarily behavioral methods (including simulated environments and computer-based tasks), but supplement behavioral results with neurophysiological data using event-related potentials (ERPs).
