Research Interests:

Psychotic disorders (e.g., schizophrenia) are devastating for patients and their families as they involve the onset of symptoms and significant impairment during late adolescence- a critical developmental period when youth are only just starting to make a transition into independence.  These disorders are highly prevalent, and once diagnosed, involve a chronic course and bleak prognosis.  However, an emerging research field suggests that we can now effectively identify those who are at imminently high-risk for psychosis, several years before onset.  These youth exhibit attenuated psychosis symptoms (e.g., experiencing unusual thoughts, seeing brief shadows, hearing strange sounds).  Those who meet criteria for a prodromal (high-risk) syndrome have a significant chance of developing schizophrenia or an affective disorder with psychotic features within a short period.  This serves as a foundation for a line of research that suggests that if we can identify high-risk adolescents and provide early intervention, the course of illness will be improved or perhaps prevented entirely.  

My research involves developing and applying conceptual models to work with adolescents and young adults exhibiting high-risk syndromes as well as those who have recently developed psychotic disorders.  I conduct prospective longitudinal studies that follow a range of characteristics that may be used to enhance identification of these individuals, predict who among them may eventually transition to psychosis, and concurrently, refine understanding of pathophysiology.  Additionally, I utilize the information to develop novel targeted treatments and remediations.   I am also keenly interested in moving understanding and intervention to earlier developmental periods and clinical phases, including the premorbid stage and childhood.  

My lab employs a range of cognitive neuroscience-based techniques and quantitative approaches, and we primarily focus on motor, affective and cognitive processing as well as the role of stigma and other environmental stressors in the pathophysiology of psychosis.  The website below describes this work  in detail and provides more information about the team.
