Research Synopsis


Using brain stimulation, neurocognitive, and neurophysiological approaches, my research focuses on understanding the mechanisms that underlie the cognitive deficits associated with schizophrenia and on developing novel interventions to enhance cognition in schizophrenia across the lifespan.
