Dr Ashwin Venkataraman is an Old Age Psychiatrist (SpR) at South London and Maudsley NHS Trust. Before this he was an Alzheimer's Society Clinical Research Fellow at the UKDRI at Imperial College London undertaking his PhD in PET and MRI Imaging of the Cellular Phase of Alzheimer's Disease with Prof Paul Matthews. He was awarded the Advances in Alzheimer’s and Parkinson’s Therapies AD/PD Junior Faculty Award for this work.

His current research assesses the early changes in Alzheimer's disease by looking at cell stress, mitochondria, synapses and amyloid to understand the links between the underlying biology and the clinical expression of the disease. He also uses machine learning approaches to better optimise diagnosis, stratification and prediction of response to existing and novel therapies.

Prior to this he was an Alzheimer's Research UK Clinical Fellow at the Neuropsychopharmacology Unit at Imperial College London working on alcohol and amyloid deposition, and investigating a novel Imidazoline-2 receptor radioligand for Alzheimer's disease.

He is a Member of the Royal College of Psychiatrists. Before this he was an NIHR Academic Clinical Fellow, Academic Foundation Programme Doctor, and graduated from University College London Medical School.
