Professor Edison is the Professor of Neuroscience and Clinical Professor in the Division of Neurology, Faculty of Medicine at Imperial College London. He is a consultant at Imperial College Healthcare NHS trust - Hammersmith Hospital, St Mary’s Hospital and Charing Cross Hospital”. He is also an honorary Professor at Cardiff University.

Prof Edison’s research has focused on neuroimaging with novel molecular probes using PET and magnetic resonance techniques for imaging pathophysiological changes associated with Alzheimer’s disease, Parkinson’s disease, and other neurodegenerative diseases. He has extensive experience in PET imaging in different neurodegenerative and neuroinflammatory conditions. Combined with his clinical expertise in different types of degenerative diseases and dementia, he has investigated the relationship between amyloid deposition, microglial activation, and glucose metabolism in various disorders, along with evaluating different transporters in the brain. His work in assessing microglial activation and amyloid load showed that both of these are increased in Alzheimer’s disease, and that microglial activation correlates with cognition, while amyloid load does not correlate with cognition. He was a HEFCE Clinical Senior Lecturer before he became a Professor of Neuroscience.

His work now focuses on neuroinflammation and the interplay between inflammation and immunity in neurodegenerative and neuroinflammatory disease, and relating these with genetic information. He is also evaluating methods of modulating inflammation and amyloid in Alzheimer’s disease, and the influence of cardiometabolic factors on the development of neurodegenerative diseases by means of clinical and preclinical studies.

He leads the Imperial College Memory Research Centre, and is the Chief Investigator of several imaging studies using PET and MRI, and heads multicentre studies evaluating novel treatment of Alzheimer's and other neurodegenerative diseases. He also runs a memory clinic at Imperial College Healthcare NHS Trust.
