Dr Emma Matthews

Reader in Neurology
Academic neurologist studying genetic neuromuscular disorders

Dr Matthews is a Consultant Neurologist specialising in Neuromuscular disorders at St George's University Hospitals NHS Foundation Trust and Reader in Neurology at St George’s University of London. The Atkinson-Morley Neuromuscular Centre received a Neuromuscular Centre of Excellence Award in both clinical and research activity by Muscular Dystrophy UK in 2024. Dr Matthews is the Neurology Lead for the SE Genomic Medicine Service Alliance and was appointed as the Genomics CAG Director at St George's in October 2023.

Dr Matthews studied Medicine at the University of Aberdeen. She was awarded a PhD in Neuroscience from the Institute of Neurology, University College London before undertaking higher specialist training in neurology at the Royal Free Hospital and the National Hospital for Neurology and Neurosurgery (NHNN) in London.

From 2014-2020 Dr Matthews worked as an academic consultant neurologist at the Institute of Neurology, UCL funded by fellowships from the NIHR and Wellcome. She joined SGUL in 2021 funded by a Clinical Academic Research Partnership from MRC and NIHR. Her main academic interests are in genetic neuromuscular disorders. She has a particular focus on channelopathies and myotonic disorders including severe paediatric presentations and how neuromuscular excitability genes may contribute to sudden death. She collaborates extensively with the inherited cardiac conditions team (Prof Behr). She also collaborates with Dr Dan Osborne in the development and characterisation of zebra fish models of healthy muscle development and genetic neuromuscular disorders. She has authored 5 book chapters and >100 peer reviewed papers in journals including the Lancet, Lancet Child and Adolescent Health, JAMA and Brain.
