Research Interests

I am a neuropsychologist with a longstanding interest in cognitive neuroscience. I have devoted my career to understanding the neural basis and nature of fundamental cognitive deficits in neuropsychiatric disorders. In ongoing work, my lab is collaborating with Dr. Robert Stickgold to investigate the contribution of abnormal sleep to cognitive deficits in schizophrenia. Sleep plays a critical role in memory consolidation and renders cognitive performance faster, more accurate, and less reliant on limited capacity processing resources (i.e., more efficient and automatic). Recent evidence suggests that sleep-dependent memory consolidation is paralleled by changes in neural activity during task performance resulting in more efficient spatiotemporal patterns of brain activation. This led us to hypothesize that sleep plays a critical role in cognitive deficits and associated inefficient brain activation patterns in schizophrenia. We have repeatedly replicated our findings of deficient sleep-dependent memory consolidation schizophrenia, identified a specific mechanism (reduced sleep spindles), and in preliminary work found that eszopiclone can increase spindles. Our present projects incorporate electroencephalography, magnetoencephalography functional MRI and genetics to elucidate the links between deficient sleep-dependent memory consolidation and sleep spindles, identify effective treatments and identify genetic contributions. This research program aims to (i) substantially enhance our understanding of the pathophysiology of schizophrenia, (ii) expand current models of cognitive deficits and (iii) identify interventions that significantly improve quality of life.
