I am a neuropsychologist whose research program uses multimodal neuroimaging techniques to illuminate the neural basis and nature of fundamental cognitive deficits in neuropsychiatric disorders, particularly schizophrenia and autism, so that they can be effectively treated.  One line of inquiry focuses on the effects of abnormal sleep on memory consolidation.  Patients with schizophrenia show deficient sleep-dependent memory consolidation that may contribute substantially to impaired daily function.  Understanding this contribution may open new avenues for treatment.  Another major focus involves examining the contribution of aberrations in the functional and structural connectivity of specific neural networks to core features of autism.  One of these studies involves using connectivity within the speech/language networks of the brain as both predictors and correlates of response to intensive therapy for speech in minimally verbal children with autism.
