Dr. Hannan specializes in the treatment of trauma-related disorders (such as Posttraumatic Stress Disorder), Borderline Personality Disorder, and anxiety disorders. She believes in the importance of fostering a supportive, collaborative, and validating therapeutic environment while delivering evidenced-based therapies. Dr. Hannan has received training in Cognitive Behavioral Therapy (CBT). Specifically, she has extensive experience providing trauma-focused treatments, such as Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT).

As an Assistant Professor, Dr. Hannan conducts research in the broad field of traumatic-stress. She is particularly interested in how emotion dysregulation may serve to maintain trauma-related symptoms over time. Dr. Hannan is also very interested in examining the ways in which we utilize other people to help regulate our emotions (for example, seeking out a friend for validation). Dr. Hannan truly values the integration of research and practice. She uses the scientific literature to inform her treatment plans; in addition, she uses her experiences with clients to inform her research.
