The Team

Allan Reiss, MD
Director of the Center for Interdisciplinary Brain Sciences Research at Stanford, Howard C. Robbins Professor in Psychiatry and Behavioral Sciences, Professor

Dr. Reiss is board-certified in child and adult psychiatry and has worked with families having one or more members with Fragile X, in both the clinical and research settings, for over 40 years. Allan saw his first family with affected family members in 1982. Since then, he has sought to contribute meaningful scientific and clinical knowledge to the field with the overarching goal of improving outcomes and quality of life among affected individuals and their families. In his spare time, he pursues his strong interest in space sciences and music.

Scott Hall, PhD
Professor of Psychiatry, Director of Behavioral Services and Behavioral Sciences

Dr. Hall received his doctorate in psychology from the University of London and has been a board-certified behavior analyst since 2002. His research interests include understanding the complex interplay between genetic and psychosocial factors underlying behavioral symptomatology in children with genetic syndromes. Scott became interested in Fragile X while working on his PhD tracking the early development of behavioral issues in children with intellectual disabilities. His study sample included a young boy with Fragile X who would bite his hand when he became anxious, and this led to his long-time efforts to understand better how behavioral interventions can contribute to treatment for Fragile X syndrome. Scott is a fan of rock music and loves to travel.

Tracy Jordan, PhD
Clinical Instructor and Psychologist in the Department of Psychiatry and Behavioral Sciences

Dr. Jordan earned her doctorate in clinical psychology with an emphasis in pediatric neuropsychology from Palo Alto University in 2019. She has worked with families affected by Fragile X syndrome and other neurodevelopmental disorders in clinical and research settings for 10 years. Her research interests include understanding genetic and environmental influences on neuropsychological functioning in individuals with neurodevelopmental disorders as well as parenting stress associated with caring for children with Fragile X syndrome and other neurodevelopmental disorders. Tracy first became interested in Fragile X syndrome in 2012, when she was working as an ABA therapist providing early intervention services to young children with Fragile X syndrome and other developmental disabilities. When not at work, Tracy is a runner, a hiker, and a yoga practitioner.
