Current Research

In the Personality, Psychopathology, and Psychometrics Laboratory, we pursue two interrelated programs of research broadly relevant to measurement of and theory related to personality and psychopathology: (a) research aimed at better understanding the phenotypic description and structure of personality and psychopathology, especially as related to personality pathology and the mood and anxiety disorders, and (b) applied psychometric research designed to create, improve upon, or evaluate psychological assessment tools.  In addition, we are interested in research aiming to translate the above line of research into clinically and practically useful applications.
