I will be reviewing applications for a graduate student for Fall 2022
My research interests are in the areas of diagnosis and classification of mental disorders, personality disorders (particularly borderline personality disorder), substance use disorders, psychometrics and clinical assessment, the relationship between personality and psychopathology, professional issues in clinical psychology, affective instability, emotional dysregulation, and ambulatory assessment methods. Almost all of my research at this point involves Ambulatory Assessment.

1. Ecological momentary assessment and ambulatory assessment: Ambulatory assessment (AA) encompasses a wide range of methods used to study people in their natural environment, including momentary self-report (e.g., ecological momentary assessment [EMA]), observational, and physiological (e.g., cardiac and respiratory activity) methods. Since 2004, I have worked on several projects that use AA to examine mood, impulsivity, personality, and substance use in those with BPD or other emotional dysregulation disorders. I have co-authored articles on the use of EMA/ESM approaches in clinical and psychological science. I have received funding from NIAAA and NIMH to continue this line of research on emotion dysregulation, affective instability, and alcohol use.

2. Personality, Personality Disorders, and Substance Use Disorders: Because BPD is frequently associated with substance use disorders (SUDs), I began to study the reasons why these conditions frequently co-occur within the same individuals. To date, I have published many papers on the topic of personality disorders and SUDs. In addition, I have served as Co-Investigator on two federally-funded grants (both from the NIAAA) that support projects that will provide data to address these and related questions.

3. Intensive longitudinal data analysis: The amount of data that can be collected using AA methods is exponentially larger than what many psychological scientists are used to managing. AA data are often collected over much of the 24 hour day and over many days. In some of our studies, participants contribute over 10,000 data points a day. Therefore, expert data management and expertise in quantitative methods appropriate for “big data” like these are needed. We have published several papers proposing unique approaches to analyzing data for these types of studies. For example, our papers have focused on conceptualizing and quantifying dynamic processes like affective instability, impulsivity, and undifferentiated negative affect.

4. Borderline Personality Disorder: Diagnosis, description, and etiology (including genetics): Over the last 30 years, I have studied borderline personality disorder (BPD), and I have been funded by the NIMH, NIAAA, and research foundations for these projects.

5. Dimensional models of personality disorder: There are a number of problems with the categorical system of personality disorder diagnosis that is codified in DSM-5. For example, the personality disorder categories are quite heterogeneous with regard to symptoms and traits, and a great deal of comorbidity among personality disorder diagnoses is frequently observed. An attractive alternative to representing personality pathology and disorder in a categorical manner (i.e., present versus absent) is a dimensional model of classification. My work in this area has been both conceptual and empirical. I have published several papers on the problems inherent in categorical systems of personality disorder diagnoses, as well as on the available dimensional models of personality and personality pathology that might be adopted. Further, several of my published studies have presented data directly relevant to this topic, focusing primarily on the five-factor model of personality.
