My research focuses on how various visual (e.g., macular degeneration), cognitive (e.g., stress, dual-tasking), and the loss of other senses (e.g., hearing loss) effect the visual system, attention, and in particular, eye movements. This research employed traditional techniques such as psychophysics and eye tracking, as well as new techniques such as computational neuroscience, gaze-contingent stimuli modifications, augmented virtual reality, as well as studying the underlying neural activity using EEG. Recently, I have also employed these techniques in the area of aviation, to study stress and fatigue in pilots
