Gary is a newly qualified junior clinician-scientist who took up the Claringbold Medicine Scholarship to start medical training at the University of Cambridge in 2005. As a second-year undergraduate in 2007, he was awarded the Gregon and Benn Award (Trinity Hall, University of Cambridge) for research exchange to Yale University's Department of Biomedical Engineering. In 2008, Gary was selected for the Frankl Award (Trinity Hall, University of Cambridge), The Wellcome Trust and The Physiological Society Vacation Scholarships for cardiovascular research at Cambridge, and a Master's scholarship for MPhil study in Computational Biology at the Cambridge-MIT Institute, which he declined to take up a BBSRC CASE Collaborative Doctoral Training Award, as 1 of the 3 recipents across three Departments selected from an open recruitment exercise. He conducted research in cardiovascular MRI at the Royal Brompton Hospital as a clinical student of Imperial College London. He started a Master of Public Health (MPH) degree in 2014 (2016 completion date).

Gary received his PhD from Cambridge in July 2015, joining HKU's LKS Faculty of Medicine in its School of Biomedical Sciences (formerly the Department of Biochemistry) as Assistant Professor one month later. To date, he is the first professoriate staff member in the Faculty to have submitted > 30 first author publications within a 12-month period whilst having the highest teaching commitments (> 185 hours). In 2016, he was awarded the Croucher Foundation Clinical Assistant Professorship at The Faculty of Medicine, The Chinese University of Hong Kong.

Gary has been elected a Fellow of the Cambridge Philosophical Society (2009), Linnean Society of London (2014), Royal Society of Public Health (2016) and Institute of Biomedical Sciences (2016) and is a Chartered Scientist of the United Kingdom (2016).

With a track record of > 30 publications, > 300 citations and an h-index of 11, Gary's work (impact factor in brackets) has been published in journals such as Heart (5.6), Acta Physiologica (Oxford) (4.1), Frontiers in Physiology (4.0), PLoS ONE (3.1), the official journals of the European Heart Rhythm Association, Europace (4.0), and of the Japanese Heart Rhythm Society and the Asia Pacific Heart Rhythm Society, Journal of Arrhythmia.

i) Pre-clinical cardiac electrophysiology

To elucidate the molecular mechanisms underlying atrial and ventricular tachycardia using an ex vivo mouse model in Langendorff perfusion mode by monophasic action potential and bipolar electrogram methods during electrical pacing. Our work is largely performed at the systems level, attempting to explain arrhythmogenesis by abnormalities in conduction (e.g. reduced conduction velocity, CV; increased CV dispersion) and repolarization (e.g. prolonged or shortened action potential duration, APD; increased transmural dispersion of repolarization, TDR; reduced refractory period, RP), as well as dynamic substrates of abnormal CV and APD restitution.

His latest work aims to understand the pathogenesis of tachycardia-bradycardia syndrome, an under-investigated clinical entity thought to be a variant of sick sinus syndrome, by examining mRNA expression of key ion channel genes responsible for pacemaker activity in excised sinoatrial nodal tissue using RT-PCR, and correlating these with electrophysiological parameters such as sinus node recovery time, intrinsic and resting heart rates measured in vivo:
