She has been a full time Neurology Consultant at Great Ormond Street Hospital since 2005.
Dr Hemingway's PhD from Imperial College London explored the patient response to brain inflammation and infection, and she has used the expertise gained from this to provide specialised clinical care to children with rare neuro-inflammatory disorders, as well as also providing care for children with many other neurological problems.
Dr Hemingway has worked and trained in neurology at Red Cross Children’s Hospital in South Africa and The Johns Hopkins in the USA and in the UK.
Dr Hemingway has established the Demyelinating Disease service at Great Ormond Street Hospital, and now runs one of the largest clinics in the country for children with multiple sclerosis and other rare demyelinating disorders.
She has an ongoing research role in this area and is an active member of both the UK and the International Paediatric MS Study Group. She is an Honorary Clinical Lecturer at both Imperial College London and the UCL Institute of Child Health.
