Research Interests

The lab is focused on how retinal cell types are i) produced and ii) maintained.  

Retinal cell death plays a role in all of the main causes of blindness. Once killed, retinal neurons are lost forever. These cells cannot be regenerated in humans.

Deciphering how retinal neurons are produced during development might help us to regenerate retinal tissue artificially. Cells could be generated in the lab, and then transplanted into individuals to replace the cells that they have lost.  

Understanding the degenerative process might provide new approaches that could help prevent or mitigate degeneration.
