Research Interests

Mammalian Developmental Genetics

My research group aims to understand the molecular mechanisms regulating mouse ocular morphogenesis from the brain and retinal neurogenesis. We are investigating the genetic pathways underlying these processes during mammalian 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 a specific type of neuron, although multiple fates are available 2) the role of the optic nerve head in patterning the retina and 3) how integrated signaling instructs the optic vesicle to grow out of the brain and undergo specific morphogenetic movements .
