Research Interests

Key interests: Molecular mechanisms in developmental defects of the eye and CNS

Cellular mechanisms important in the development of the human central nervous system include differentiation, cell migration and homeostatic apoptosis. Epithelial fusion is particularly important and abnormalities are linked to a number of CNS diseases associated with failure of embryonic fissure closure. My research group is focused on understanding the molecular control mechanisms important in epithelial fusion in the developing CNS. Our model system is optic fissure closure in the eye, in animal models such as the zebrafish.

Epithelial fusion defects in the eye are relatively common, examples are ocular coloboma (0.5:10,000) and anophthalmia/microphthalmia (2.1:10,000). In addition to studies in zebrafish, we have built a database of coloboma families and patients. With this database, to date we have identified two new genes causing ocular coloboma: ZFHX1BFADD.
