I am a Clinical Professor of Ophthalmology.   My clinical activity takes place at the Belfast Health and Social Care Trust and is mainly dedicated to patients with glaucoma.  I have surgical expertise on complex glaucomas and cataract. 

My academic career at the Centre fof Public Health (Health Services Research Group) is focused in trying to improve eye care and investigating the efficacy, efficiency and safety of new technologies for eye diseases (e.g., treatments, diagnostic tests, models of eye care).  I have expertise in primary and secondary research methodology.   I am Chief Investigator of several trials, including EAGLE, an international multicentre RCT comparing primary lens extraction versus laser iridotomy in patients with angle-closure glaucoma; GATE, an UK-based multicentre diagnostic study evaluating automated imaging technologies in glaucoma; and CHAMP-UK, a multicentre randomised trial evaluating low dose atropine eye drops for children with myopia.   I am co-applicant of several UK-based trials: TAGS and GLAURIOUS (on glaucoma), DIAMONDS and EMERALD (on diabetic retinopathy), EDNA and MIRROR (on age-related macular degeneration).  I have received research funds from MRC, NIHR-EME, NIHR-HTA, Horizon 2020, and charities.   I have published over 210 peer-reviewed papers, over 20 book chapters, and edited three books.   My work has been cited over 5000 times and my current Scopus h-index is 40.
