Steven Barnes, PhD:
Hi, I’m Steve Barnes. I have a PhD in retinal neurobiology, and I’m a professor at UCLA, working at the Doheny Eye Institute. I’ve been to about 20 ARVO meetings over the decades, and it’s always been great, and it’s always exciting to bring your latest discoveries in research to the meeting. The project we’re presenting at ARVO is about human stem cell-derived retinal ganglion cells, the cells that die in diseases such as glaucoma and many other optic neuropathies.
