Research Interests: Investigation of schizotypy and schizophrenia from experimental and developmental psychopathology perspectives. These studies focus on developing and testing symptom, trait, cognitive, biobehavioral, and genetic markers of schizophrenia and schizophrenia-spectrum disorders. This program of research traces its roots back to Paul Meehl's landmark work on schizophrenia and schizotypy and to the pioneering work on psychosis proneness by the Chapmans. Specifically, this work focuses on identifying individuals who are at risk for developing schizophrenia or related conditions. Current projects involve cross-sectional and longitudinal studies with schizotypic young adults. Assessment of psychopathology in daily life. My laboratory coordinates the UNCG Center for the Assessment of Life Experiences. These studies examine the expression of cognition, affect, personality, and psychopathology in daily life using experience sampling methodology. Investigation of bipolar spectrum psychopathology. These studies focus on the examination of the development and expression of hyperthymia and bipolar-spectrum disorders.
