Background

Dr Kwan is a UK-trained stroke specialist. He received his specialist training in general internal medicine and geriatric medicine in Wessex (UK), clinical neurology fellowship at Queen Square London (Institute of Neurology, University College London), and plant-based nutrition at Cornell University (USA). From 2006 to 2013, he worked as the stroke consultant and head of department of stroke medicine at the Royal Bournemouth Hospital, and the clinical lead for the Dorset Stroke Network. In 2009, he was appointed as a visiting professor in medicine at Bournemouth University. In December 2013, Dr Kwan travelled overseas and was appointed as a clinical associate professor and honorary consultant in geriatric medicine at the University of Hong Kong (HKU), developing a second specialist interest in dementia. At HKU, he founded the HKU Gerontology Research Laboratory and is primary investigator (PI) for several dementia, heart and brain cohorts; he currently has two postgraduate students in HKU involved in biomedical and clinical PhD projects, and ongoing collaborations with UCSF and UCL. In May 2018, Dr Kwan returned to the UK as a consultant stroke physician at Charing Cross Hospital. He remains as a visiting professor at Bournemouth University and an honorary clinical associate professor at the HKU.

His current clinical and research interests are hyperacute stroke interventions and post-stroke cognitive impairment, respectively.
