Our research program investigates the mechanisms underlying the symptoms and disturbances in schizophrenia and related psychoses, the heritability of these features, the potential for remediation with somatic and other treatment modalities, and the proposed causes for their occurrence. Central areas of study include the cognitive or information processing disturbances (e.g. in language, memory, attention, etc.) and neuromotor features of these disorders. The main focus of our research has been to develop precise, preferably laboratory based measures that capture the kinds of cognitive disturbances we observe clinically. Using these measures, we explore the nature of cognitive and neurological abnormalities to determine how they manifest themselves and how they are related to other cardinal psychopathologic features (for example, formal thought disorder, delusions, sensory abnormality and emotional responses). These efforts have been complemented by the recent development of a Psychophysiology Laboratory, primarily devoted to the study of Event Related Potentials, in collaboration with Patricia Deldin, PhD, Associate Professor of Psychology in the Department of Psychology, Harvard University.

A second focus of our research is the development of more effective pharmacotherapies and evidence-based clinical guidelines for the administration of antipsychotic medications. The search for more reliable measures of behavior complements these parallel investigations of the relative efficacy and tolerability of a growing array of antipsychotic agents. The ability to accurately measure and analyze multiple indices of cognitive and motor function during treatment with a specific drug yields information about clinical response, underlying pathology and diagnostic subtypes.
