Dr Edison is a Clinical Senior Lecturer in Neuroscience in the Department of Brain Sciences at Imperial College London and an honorary Professor at Cardiff University, Wales. He is the Editor-in-Chief of the journal BRAIN CONNECTIVITY. He is also a Consultant Physician at Hammersmith Hospital, London.

Dr. Edison, after his clinical training (MD) did his MPhil and PhD at Imperial College London, and then completed his higher training in London Deanery and obtained his CCT from the Postgraduate Medical Education and Training Board. He then became a Fellow of Royal College of Physicians, Ireland and Fellow of Royal College of Physicians, UK.

He has received prestigious MRC clinical research fellowship award, HEFCE Clinical Senior Lectureship Award, and research scholarships. He is currently Clinical Senior Lecturer in the Department of Brain Sciences, Faculty of Medicine at Imperial College London and an Honorary Professor at Cardiff University, Wales. He is also a Consultant at Hammersmith Hospital, London.

His research is 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 and MR imaging in different neurodegenerative and neuroinflammatory conditions. His initial work evaluated one of the first amyloid imaging agent in Alzheimer’s disease at the MRC Cyclotron Unit, Imperial College London, Hammersmith Hospital, and has published seminal papers in the field. Since then, combined with his clinical expertise in different types of degenerative diseases and dementia, he has investigated the relationship between amyloid deposition, microglial activation, glucose metabolism, and MRI changes in different disorders, along with evaluating different transporters in the brain.

He has published in high impact journals such as Brain, Annals of Neurology, and Neurology, and has received grants from the Medical Research Council, NIHR/HEFCE, Alzheimer’s Society, Alzheimer’s Research UK, Alzheimer’s Drug Discovery Foundation US, and other funders. He collaborates closely with Novo Nordisk, GE Healthcare, Novartis, Piramal Life Sciences, and Astra Zeneca. He has also received several best paper awards internationally and published in leading scientific journals.

He is the editor-in-chief of Brain Connectivity, an associate editor for Journal of Alzheimer’s Disease, and serves in the editorial boards of Journal of Neuroimaging and Contrast Media & Molecular Imaging.

Dr Edison’s research on neuroimaging with novel molecular probes using PET and magnetic resonance techniques for imaging pathophysiological changes associated with Alzheimer’s disease provided novel insight into the role of neuroinflammation in Alzheimer's trajectory, and proposed that there is differential microglial activation (protective and damaging) in different stages of the disease. 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 different 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 microglial activation correlates with cognition, while amyloid load does not correlate with cognition.

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 the 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 pre-clinical studies.

He is the chief investigator for several multicentre studies, one of which is evaluating Liraglutide in treatment of Alzheimer's disease, which is conducted in 24 sites.

He leads the Imperial College Memory Research centre, and is the Chief Investigator of several other 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
