Professional background

Dr Weil graduated from Downing College, Cambridge with a first class degree in medical sciences, before studying clinical medicine at University College London.

She trained in general medicine at the Hammersmith, Brompton and Whittington hospitals (MRCP in 2004). She trained in neurology at the Royal Free Hospital and the National Hospital for Neurology and Neurosurgery.

She is now a Wellcome Trust clinician scientist and honorary consultant neurologist at the National Hospital for Neurology and Neurosurgery. She runs clinics in cognitive disorders, movement disorders and general neurology and has a particular interest in hallucinations and cognitive disorders in Parkinson’s disease.

Research interests

Dr Weil’s PhD research was at the Wellcome Trust Centre for Neuroimaging, UCL, where she examined the integration of visual signals in the healthy and damaged brain.

She was awarded a post-doctoral UCL excellence fellowship in 2014 to study visual changes in Parkinson’s disease.

She now leads a Wellcome-funded group that aims to shed light on how dementia happens in Parkinson’s disease, using visual perception measures and neuroimaging to detect early clues of cognitive involvement in Parkinson’s disease.
