Biography

Susan Leung graduated from the University of Bristol, England, with a BSc Degree in Pharmacology, and obtained a PhD Degree in Pharmacology at the University of Hong Kong. Upon graduation, she was awarded the Croucher Foundation Fellowship for a postdoctoral training at Department of Pharmacology and Therapeutics at the University of British Columbia, Canada. She then returned to the University of Hong Kong for further postdoctoral training at the Department of Pharmacology. She was Research Assistant Professor and then Assistant Professor at the University of Hong Kong for the period of 2005-2014. She is now Associate Professor at the Department of Pharmacology and Pharmacy. Her research has mainly focused on the study of vascular reactivity under physiological and pathological conditions, and under the influence of different pharmacological agents.
