Dr. Daniel Geller founded the Pediatric Obsessive Compulsive Disorder (OCD) Program in 1992. At Massachusetts General Hospital (MGH), he has collected and characterized a large sample of children and adolescents with OCD and Tic disorders. Among his research efforts is collaborative work with other leading universities and the National Institute of Mental Health for the study of genetics of psychiatric disorders. Dr. Geller is a founding member of the International OCD Genetics Consortium, collaborating with senior scientists from many countries, with the goal of identifying genes responsible for OCD and delineating mechanisms by which genetic vulnerabilities are translated into clinical symptoms.

Dr. Geller is the recipient of several honors and awards in medicine and developmental pediatrics, notably from the American Academy of Child and Adolescent Psychiatry, Obsessive-Compulsive Foundation and Tourette's Syndrome Association. He is a member of the Society of Development Pediatrics and several expert panels, including the American Academy of Child and Adolescent Psychiatry and the National Institute for Clinical Excellence of the Royal College of Psychiatrists, London. He completed his training as a general and developmental pediatrician in Australia and then trained as resident and chief resident in general and child and adolescent psychiatry at Johns Hopkins and Stanford medical schools.

Dr. Geller is triple-boarded in Pediatrics, General Psychiatry and Child Psychiatry. In 1992, he was recruited to McLean and Massachusetts General Hospitals where the Pediatric OCD Program was established. Since 2003 he has worked at MGH full time in the Pediatric Psychopharmacology Program and the Psychiatric Neurodevelopmental Genetics Unit.
