My interests are in the genetic epidemiology of common eye diseases such as myopia, cataract and glaucoma, using twin studies to model the heritability of these traits and modern high-throughput genotyping technology such as genome-wide association scans which we have on over 5000 twin subjects in the Department of Twin Research & Genetic Epidemiology.
I am also a Clinical Consultant Ophthalmologist based at St Thomas' Hospital, London, specialising in the management of strabismus (squint) in adults and in children, including squint surgery and botulinum toxin injections.
