William Whiteley is a Scottish Senior Clinical Fellow (funded by CSO) in the Centre for Clinical Brain Sciences, University of Edinburgh.

He is also Senior Clinical Fellow in the Nuffield Department of Population Health, University of Oxford; an International Fellow at the Population Health Research Institute, University of McMaster (Canada); and a consultant neurologist in NHS Lothian, working with patients with TIA, stroke and dementia. 

His work seeks to elucidate the mechanisms for prevention of disability due to stroke and dementia through the design, delivery and analysis of epidemiological studies and clinical trials. Of particular interest are: the contribution of vascular risk factors to dementia; the very long term follow-up of randomized trials; clinical diagnosis; and the better use of large electronic health record datasets for more efficient clinical trials and cohort studies.

He founded the Edinburgh Clinical Natural Language Processing Group with Dr Honghang Wu and Dr Bea Alex, a multidisciplinary team at the University of Edinburgh who apply natural language processing to clinical text.

He has founded and run the Edinburgh Stroke Winter School and clinical PhD research training programs in stroke (funded by the Stroke Association) and dementia (funded by the Alzheimer's Society and University of Edinburgh). He has been supported by personal fellowships from the UK MRC (Clinician Scientist fellowship 2010-2015), the Chief Scientist’s Office (2006-2009, 2018-2025), and his work by the Alzheimer's Society, the Stroke Association and Chest, Heart and Stroke Scotland.
