Prof Christopher Leung is a clinician-scientist with research focus on glaucoma investigation and management. He was awarded the Chevening Postgraduate Scholarship in 1996 to study molecular medicine at the Imperial College London and the Croucher Foundation Fellowship in 2006 to complete a clinical and research fellowship in glaucoma at the Hamilton Glaucoma Center, the University of California, San Diego (UCSD).

Prof Leung is Section Editor of British Journal of Ophthalmology, Contributing Editor of International Glaucoma Review, Editorial Board Member of Ophthalmic Epidemiology, Translational Vision Science & Technology, and Ocular Surgery News (Asia Pacific Edition), and reviewer of over 30 peer-reviewed scientific journals.

Prof Leung has received a number of research and service awards including the National Best Paper on Prevention of Blindness in the World Ophthalmology Congress (2006), UCSD Schanzlin Research Award (2007), American Academy of Ophthalmology Achievement Award (2008), Asia Pacific Academy of Ophthalmology Nakajima Award (2010), Asia Pacific Academy of Ophthalmology Achievement Award (2010), Association for Research in Vision and Ophthalmology Alcon Clinician-Scientist Research Award (2010), Asia Pacific Joint Glaucoma Congress Young Scientist Award (2010), World Glaucoma Congress Science Award (2009 and 2011), Asia-Pacific Glaucoma Society Young Investigator Award (2012), American Academy of Ophthalmology Secretariat Award (2012), Asia Pacific Academy of Ophthalmology Distinguished Service Award (2014), and American Academy of Ophthalmology Senior Achievement Award (2015).
