Jeremy studied medicine at The Middlesex Hospital Medical School and psychology at University College London. He then took on higher training in paediatrics and psychiatry before becoming Clinical Lecturer in Child & Adolescent Psychiatry at Great Ormond Street Hospital and the Institute of Child Health. At the Institute of Child Health he completed a research doctorate thesis on the psychiatric, psychological and behavioural functioning of children with intellectual disabilities.

He took up his Senior Lectureship at St. George’s, University of London, in 1993, progressing through Readership to Professor. He began his current positions at the Trust and Institute of Psychiatry in September 2009.


Jeremy’s MD thesis covered his research on the association between the fragile X syndrome and disturbances of conduct, social functioning, hyperactivity and autism. Findings have been disseminated widely through conference presentations and proceedings, journal articles, book chapters and media coverage.

He has extensively researched the developmental and psychological aspects of a range of other genetic conditions, including: Down Syndrome, Smith-Magenis Syndrome, Cleidocranial Dysostosis, Dancing Eye Syndrome, Duchenne Muscular Dystrophy, Turner Syndrome, Cohen Syndrome, Neurofibromatosis, Chromosome 15 anomalies, Fetal Alcohol Spectrum Disorders, Autism Spectrum Conditions, Attention Deficit Hyperactivity Disorder (ADHD), Obsessive-Compulsive Disorder, Tic Disorders, Epilepsy and Sleep Disorders.

Jeremy has investigated and written on cognitive-behavioural psychotherapeutic approaches for children and young people with developmental disabilities, and has explored the possible benefits of various medications including folic acid, clonidine, melatonin, carbamazepine and SSRIs. He continues to research the relationship between neuropsychological, neurophysiological and neuroanatomical dysfunctions in fragile X syndrome, and the precise genetic abnormality. He also continues to investigate the trajectories of intellectual, social, communicatory and behavioural development, and the psychological status of fragile X female carriers and male premutation carriers.

He is interested in the psychological correlates of physical diseases including epilepsy, inflammatory bowel disease and leprosy.


Jeremy is passionate about the mental health needs and welfare of children and young people with developmental disabilities, and also those of their families. He engages frequently in advocacy activities that include school and social services meetings, tribunal appearances, teaching, lecturing and consultation, and support for individuals facing legal issues relating to their developmental disadvantage.
