Dr. Gratz is Director of Personality Disorders Research and Director of the Dialectical Behavior Therapy Clinic. Dr. Gratz's clinical and research interests focus on the role of emotion dysregulation and experiential avoidance in borderline personality disorder (BPD) and deliberate self-harm. In particular, her research focuses on understanding the nature and consequences of emotional dysregulation and avoidance in BPD and self-harm (through the use of novel behavioral/experimental paradigms), and applying this understanding to the development of more effective treatments for these conditions. She is also interested in the emergence of borderline personality and related pathology among children and adolescents, and the intergenerational transmission of borderline personality pathology between mothers and their children. Recent projects include: experimental investigations of emotion dysregulation, experiential avoidance, and emotional unwillingness in BPD and deliberate self-harm; an experimental investigation of the validity, markers, and associated consequences of an anxious-avoidant subtype of BPD; an examination of the personality traits and underlying processes associated with borderline personality symptoms in childhood; an examination of the rates and correlates of deliberate self-harm among children and adolescents in low-income communities; a laboratory-based study of BPD-relevant personality traits and emotion regulation capacity among women and their 12-23 month-old children; and the further development of an acceptance-based, emotion regulation group therapy for deliberate self-harm among women with borderline personality traits.
Dr. Tull is Assistant Professor and Director of Anxiety Disorders Research. Dr. Tull's research focuses on emotion regulation within the anxiety disorders, with a particular focus on PTSD. His research examines the ways in which: (a) emotion regulation strategies that function to avoid emotion (and internal experience in general) may serve as a vulnerability factor for the development and maintenance of post-traumatic symptoms; and (b) emotional approach and acceptance (such as through mindfulness) may serve as a protective factor for anxiety disorder-related pathology. This research stems from a growing body of theoretical and empirical literature that suggests a paradoxical effect of emotional avoidance/control and, conversely, the potential benefits of accepting and being mindful of one's internal experience.
