I currently maintain two broad programs of experimental psychopathology research. The first concerns schizotypy and schizophrenia and the second concerns the longitudinal study of severe personality disorders. In the schizotypy/schizophrenia program I conduct studies of sustained attention, working memory, eye movements, motor performance, and somatosensory perception in relation to schizotypic psychopathology. In the personality disorders research program, I am currently conducting analyses of three waves of personality disorder, personality, and temperament data gathered using a longitudinal research design on a large number of young adults. I have also recently become more involved in the study of borderline personality disorder from both a neurocognitive and neurobehavioral (i.e., neurobiological) perspective. I use a variety of measurement approaches in the laboratory, including basic perception and cognitive tasks as well as psychometric methods.
Philosophy of Graduate Training:
My perspective on graduate training is in the tradition of the apprenticeship model in which students are exposed to all aspects of the research and clinical processes. In short, it is my hope that my students will develop into clear thinking clinical psychologists who are both creative researchers and competent clinicians.
