Professor Russell Dale is a paediatric neurologist with clinical and research interest in neuroimmunology, movement disorders and neuropsychiatry. He has particular interest in the discovery and use of biomarkers to diagnose neuroinflammation and immune activation of the brain. He has particular focus on the treatment of immune mediated brain disease to reduce brain injury and improve clinical outcomes. A British national, Prof Dale undertook his medical training at the University of Leeds in Yorkshire in northern England, trained in paediatric neurology at Great Ormond Street Hospital in London, and did his PhD in neuroimmunology at the Institute of Neurology in London. In 2006, he moved to Sydney Australia, and has been awarded a National Health and Medical Research Council Practitioner Fellowship since 2014. Prof Dale is Head of the Institute for Neuroscience and Muscle Research at the Children’s Hospital at Westmead at the University of Sydney in Australia. He has published over 200 peer-reviewed publications, mostly in the area of neuroimmunology, and his work has been cited according to Scopus 6700 times, over 1000 times in 2017. Prof Dale has supervised 5 PhD students to completion, and currently supervises 5 PhD students. He has been co-author on consensus definition papers of autoimmune encephalitis, and CNS demyelination in children. He has lead studies about the safety and efficacy of immune therapies used in paediatric neurology such as rituximab and intravenous immunoglobulin. Prof Dale is a strong believer in careful clinical phenotyping, and how clinical features can inform us about the biological process.
