Alexandria Chang

Research Program Coordinator

Division: Child and Adolescent Psychiatry
Department: Psychiatry and Behavioral Sciences
Institution: The Johns Hopkins University School of Medicine

My main research interests focus on developing, testing, and disseminating novel and scalable treatments, with an emphasis on OCD, anxiety, Tourette Syndrome, and related disorders. I am also passionate about elucidating the complex psychopathology of aforementioned psychiatric conditions using ambulatory assessment and network analysis. Furthermore, I am interested in synergizing digital technology and psychophysiology using evidence-based practice to promote accessible mental health solutions.
