David is a Professor at the University of Exeter Medical School and a Fellow at the Alan Turing Institute. He also holds an honorary contract with Devon Partnership NHS Trust. He moved to Exeter in 2009 having received advanced training in epidemiology and data science as a Research Associate at the University of Cambridge.
His research aims to enhance the timely detection of dementia, with a focus on developing strategies for primary and secondary prevention. He uses a combination of evidence synthesis, data science and machine learning to develop new translational insights to identify more effective interventions and enhance the diagnostic pathway for dementia. He is an expert on the evaluation of cognitive function and dementia, and is a member of the scientific advisory boards of the English Longitudinal Study of Ageing and the UCL Centre for Longitudinal Studies. He sits on Alzheimer’s Research UK’s Grant Review Board and their Clinical Policy Advisory Panel.
David is also the Exeter Institute for Data Science and Artificial Intelligence Clinical Theme Lead and the Turing Exeter University Clinical Lead. He sits on the Steering Committee and leads the Clinical Advisory Group of the Early Detection of Neurodegeneration (EDoN) Initiative and is Director of the DEMON Network an international network for data science and AI applied to dementia research and healthcare.
Prof Llewellyn leads a programme of research on dementia prevention and diagnostics, and the development of new technology for personalised medicine. He will focus during his Turing Fellowship on how advanced machine learning methods can be used to develop new algorithms and clinical systems to enhance clinical decision making.
