Research Interests

Mammalian Developmental Genetics

My research group aims to understand the molecular mechanisms regulating the formation of the mammalian lens and retina. We are investigating the genetic pathways underlying lens and retinal tissue formation during embryogenesis. This research will contribute to a better understanding of congenital eye diseases and ultimately inform therapies that can correct vision loss. Currently we are focused on understanding: 1) how retinal progenitor cells choose to become one type of neuron, although multiple fates are available to them and 2) the role of the optic nerve head in patterning the retina.
