Personal profile


Geoffrey Cloud was appointed Director of Stroke Services at Alfred Health and adjunct Professor of Stroke Medicine at the Central Clinical School of Monash University, in July 2016. Prior to moving to Australia, he had been a full time Consultant Stroke Physician and Honorary Senior Lecturer working in the Department of Clinical Neurosciences at St George’s Hospital in London.

Professor Cloud has been the Clinical Lead for Stroke in South West London and Director of The Wolfson Regional Neurorehabilitation Centre.

Professor Cloud was Associate Director for Stroke at The Royal College of Physicians of London between 2009 -2016 and helped develop the Sentinel Stroke National Audit Programme (SSNAP). He co-authored over a dozen National Stroke Improvement reports and was a member of the Intercollegiate Stroke Working party writing National Clinical Guidelines on Stroke in 2012 and 2016.

Professor Cloud was a member of the Clinical Advisory Group that informed and implemented the London Stroke Strategy in 2010 – the largest transformation of stroke services ever.

Professor Cloud has been an investigator for more than 32 randomized controlled stroke trials, and been awarded over £1M competitive grant research funding in the last 5 years.

Outside of stroke service quality improvement, his published research interests include posterior circulation stroke, novel interventions for motor recovery after stroke and understanding the needs of stroke carers.

Professor Cloud co-authored the Oxford University Press Handbook of Stroke Medicine; the second edition published in 2016.
