Anxiety disorders/social phobias – Department of Psychiatry & Behavioral Sciences

As a child and adolescent psychiatrist at the Child Study and Treatment Center, I am deeply inspired by the resilience of the youth we serve and by the collaborative spirit of our multidisciplinary teams. My work is grounded in curiosity, compassion, and respect for the complex systems that shape young people’s lives. My approach integrates evidence-based psychopharmacology with developmental and trauma-informed care, while always centering around the individual’s unique story and strengths. I value the relational and systemic dimensions of psychiatry: the interplay between family, community, and policy that influences recovery and growth. The multidisciplinary, relational model at CSTC reflects these values and continues to shape how I think about psychiatry: not only as a science, but as a deeply human endeavor.

My research interests primarily center around romantic relationship functioning and personality disorder (PD) measurement. My line of PD research centers around how the use of a trait-based, dimensional approach to assessing and measuring PDs may increase construct validity, reliability, and diagnostic accuracy relating to PDs. My romantic relationship research centers around how romantic relationship functioning and interpersonal behaviors are associated with psychopathology diagnoses and symptoms.

As a clinician, I specialize in treating suicidality and self-harm using comprehensive Dialectical Behavior Therapy; in treating PTSD using Cognitive Processing Therapy and Prolonged Exposure; and in treating anxiety-related disorders using exposure therapies like Exposure and Response Prevention for OCD and Exposure for Social Anxiety. I am also passionate about providing couples’ therapy.
