Investigating retinal blood vessel development

We work on a number of Mendelian and complex eye disorders including retinal degeneration (LCA, PR, CRD AMD), retinal vascular disorders (FEVR, Norrie disease, ROP, Coats), optic neuropathies (optic atrophy, optic nerve hypoplasia) and developmental eye disorders (foveal hypoplasia, retinal dysplasia, microphthalmia).

Techniques we use include next generation sequencing, autozygosity mapping, traditional linkage mapping, immunohistochemistry, cell–based models, whole genome siRNA screening, bioinformatics and animal models.
