My research interests are in the area of psychophysiological (topographic evoked and event-related potentials) indices of attention, cognition and emotion across the lifespan in both normal and clinical populations. My primary research focuses on sensory gating deficits of the P50 component of the auditory evoked potential in schizophrenia which I plan to extend to attention deficit/hyperactivity and post-traumatic stress disorders. Current studies involve the integration of evoked potential indices with functional MRI, and examining of the P50 in an animal model. A second area of active research in my laboratory involves sex differences in emotion processing. Current studies include examination of emotion processing across the menstrual cycle as well as fMRI studies of sex differences in emotion processing.
