As the director of the Pediatric Psychiatry OCD and Tic Disorders Program, Dr. Greenberg specializes in working with individuals with tic disorder (including Tourette syndrome "TS") and co-occuring disorders, including OCD, ADHD and body-focused repetitive behavior disorders (BFRBs).  Dr. Greenberg is currently the principal investigator (PI) of a behavioral treatment study evaluating whether a modified treatment may help improve tic, ADHD and quality of life symptoms in children/adolescents with tic disorders and co-occuring ADHD.  Additionally she focuses on the phenomenological association between tic disorders, OCD and BFRBs (specifically trichotillomania and skin-picking disorder), and collaborates with the Tourette Syndrome Assocation International Consortium for Genetics (TSAICG) regarding better elucidating the genetic underpinnings of TS and related disorders.
