研究领域

My research group aims to understand the molecular mechanisms regulating the formation of the mammalian lens and retina. We use mouse models to investigate 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 stem cell therapies to correct vision loss. Currently we are focused on understanding: 1) how lens progenitor cells stop dividing and turn into fiber cells, and 2) how retinal progenitor cells choose to become one type of neuron, although multiple fates are available to them.
