Gary Kui Kai Lau graduated in 2008 from the University of Hong Kong with a M.B.B.S and Master of Research in Cardiovascular Medicine degree. He joined the Division of Neurology, University of Hong Kong as Clinical Assistant Professor in 2011 under the Young Academic Scheme. He completed his Neurology training at Queen Mary Hospital in 2015 and subsequently a PhD in Clinical Neurosciences (Stroke medicine) in 2017 (University of Oxford Croucher Scholar) at The Centre for Prevention of Stroke and Dementia, University of Oxford, under the mentorship of Professor Peter Rothwell.  

Dr Lau's main interest is stroke and he is passionate about understanding more about how stroke can be prevented and better treated as well as how the well-being of stroke patients and their caregivers could be improved. He currently leads the Stroke Prevention and Research Group ( with projects focusing on primary and secondary prevention of stroke and dementia. He is also a co-investigator of the WeRISE programme ( which is a health and social care collaboration, with the primary aim of empowering stroke patients and their caregivers via a range of evidence-based interventions and assessments. Dr Lau's research work has been published in more than 50 international peer-reviewed journals such as Lancet Neurology; European Heart Journal; Neurology; Stroke; Arteriosclerosis, Thrombosis and Vascular Biology and American Journal of Clinical Nutrition. He has edited one book and has authored more than 25 book chapters.

Dr Lau is also passionate in teaching. He is currently the Editor of the HKU eLearning Platform in Clinical Neurosciences ( In 2014, he was awarded a Faculty Teaching Medal in recognition of his outstanding performance in teaching and promotion of good practice in teaching
