Research Interests:

Psychotic disorders (e.g., schizophrenia, schizoaffective disorder, depression and bipolar disorder with psychotic features) 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 ultra high-risk (UHR) adolescents exhibit attenuated psychosis symptoms (e.g., experiencing unusual thoughts, seeing brief shadows, hearing strange sounds).  Those who meet criteria for a UHR syndrome have a significant chance of developing schizophrenia or an affective disorder with psychotic features within a two-year 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.  In a neural diathesis-stress conceptualization of psychosis, individuals with an early biological susceptibility exhibit subtle signs of impairment in childhood. Later in development these vulnerabilities interact with maturational factors and environmental stressors, ultimately contributing to the onset of psychosis.  My research involves developing and applying this model to work with adolescents and young adults exhibiting high-risk syndromes as well as those who have recently developed psychotic disorders.  Specifically, I conduct prospective 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 from these longitudinal studies to develop novel targeted treatments and remediations.  The website below describes one such recent treatment focusing on aerobic exercise and neurogenesis that  I am currently in the process of testing in the context of a randomized clinical trial.
