My research focuses on perceptual dysfunction in psychiatric disorders, with a focus on schizophrenia. A major goal is to elucidate the neural basis of sensory and perceptual deficits in schizophrenia and examine the effects of these deficits on higher level function. A particular focus is on how perceptual dysfunction affects social cognition. Decreased ability to assess social situations and identify emotions is a major difficulty in schizophrenia. We have found that basic perceptual difficulties impact social cognitive dysfunction. A more recent focus of my work is cognitive rehabilitation of social cognitive deficits. We are also developing highly specific biomarkers of perceptual dysfunction for assessing course of illness and development of illness in high risk populations. Thus, my interests and work include clinical remediation as well as basic psychophysical, electrophysiological, and magnetic resonance imaging studies of underpinnings of perceptual deficits in schizophrenia and the brain circuitry involved.
