Geller, Daniel, MD

Director, Pediatric OCD and Tic Disorder Program, Massachusetts General Hospital


Dr. Daniel Geller founded the Pediatric Obsessive Compulsive Disorder (OCD) Program in 1992. For over 15 years, he has studied the causes, phenomenology, developmental expression, psychiatric correlates, familial patterns, genetics, treatment and outcome of OCD and related disorders that onset in youth, and has produced a coherent and comprehensive body of original research. Publications include many original papers, reviews, book chapters, and new research presentations and symposia at national and international scientific meetings. At Massachusetts General Hospital (MGH), he has collected and characterized the largest sample of children and adolescents with OCD ever assembled. The potential value of longitudinal study of this sample for the field of child psychiatry is substantial.

Dr. Geller collaborates with other research groups around the world and has won competitive grants from the National Institutes of Health, private foundations and industry. 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, where he is lead author for the Academy’s Practice Parameters for Assessment and Treatment of OCD in Children, 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 is a Fellow of the Royal Australian College of Physicians.

Dr. Geller came to the United States in 1987 to pursue advanced pediatric training at Johns Hopkins University Hospital. He subsequently trained as resident and chief resident in general and child and adolescent psychiatry at Johns Hopkins and Stanford medical schools and is triple-boarded in Pediatrics, Psychiatry and Child Psychiatry. In 1992, he was recruited to McLean and Massachusetts General Hospitals where the Pediatric OCD Program was established.
