He was previously Professor and Head of Ophthalmology and Deputy Director of the Centre for Brain Repair at the University of Cambridge.
His research is focused on developing new strategies to protect and regenerate the optic nerve in glaucoma, the leading cause of irreversible blindness worldwide. He was first in the world to demonstrate gene therapy and stem cell therapy could reduce retinal ganglion cell death in an experimental model of glaucoma.
A gene therapy for glaucoma developed in his lab is currently being progressed towards human clinical trials by a major pharmaceutical company. He has extensive experience in optic nerve injury models, including multiple animal models of glaucoma, retinal gene therapy and all relevant surgical techniques.
He is an experienced supervisor and mentor to graduate students, post docs and clinician scientists. Clinically, he specialises in the medical and surgical management of advanced glaucoma.
