My research interests lie in the areas of personality development and developmental psychopathology with an emphasis on multi-informant and multi-method assessment. My graduate work has explored the role of temperamental emotionality in internalizing psychopathology, and the influence of methodology on the conclusions that one draws in developmental models of depression vulnerability. This research was performed in the context of longitudinal designs in the hopes of creating a comprehensive model of depression risk, including temperamental, psychophysiological, and cognitive pathways. Given my long-standing interest in statistical methods, I have also explored structural, methodological, and developmental issues in assessment of personality and temperament, including maladaptive personality traits. With Dr. Lee Anna Clark, the developer of the Schedule for Nonadaptive and Adaptive Personality, we developed a significantly shortened version of this measure, the SNAP Brief Self-Description Rating Form (SNAP-BSRF) and its informant counterpart, the SNAP Brief Other-Description Rating Form (SNAP-BORF). I am presently continuing my work with Dr. Clark at the Center for Advanced Measurement of Personality and Psychopathology (CAMPP), University of Notre Dame. My postdoctoral research focuses on the structural and methodological issues in assessment of maladaptive personality traits and developing a better understanding of how such traits are related to functional impairment in daily life.
