My courses include introductory psychology, sensation & perception, cognitive neuroscience, attention & consciousness research, and neuroscience of consciousness (course descriptions below). In most of these courses, students read, discuss, and critique research articles, learn the methodological techniques of cognitive neuroscience and psychophysics, and develop novel experimental questions that can be explored in the laboratory.
My area of expertise is in cognitive electrophysiology of perception and attention. I specialize in electroencephalography (EEG), event-related potentials (ERPs), and psychophysics. Some of the major questions my research seeks to resolve are: How does brain activity differ during conscious versus nonconscious processing of objects and events? Which cognitive functions require attention and awareness and which can be carried out automatically? Are attention and awareness fully dissociable? My laboratory includes two 64-channel EEG systems that can be used to record and map the brain waves of human subjects while they perform visual and auditory tasks.
