I have a long-standing interest in how the retina converts light into electrical signals that are sent to the rest of the brain. I want to understand how this process contributes to vision and how we can leverage an understanding of retinal function to treat blindness.

 A current Postdoctoral Fellow whose interests are understanding the remodeling of retinal circuits in early steps of physio-pathologies. 

Marija Rudzite

Ph.D. Student

Project titles:
- Determining the signals sent by retinal ganglion cells to superior colliculus
- Determining how GABA inhibition shapes information processing in the retina

I'm a “bi-coastal” graduate student at Duke Neurobiology Ph.D. program working with the Sommer Lab to understand what visual signals the retina sends to different brain regions. I'm also interested in how the synaptic organization of retinal circuits relates to mathematical descriptions of neural code and visual processing. As a training retinal physiologist, I spend most of my time in the dark, but when I do see the light, I love to be outside hiking, gardening, or biking.

Staff Research Associate II

With a background in Biology and Computer Science, I am interested in computational biology and the development of precise models for studying biological systems. I am excited by the challenge of integrating data to understand retinal circuits.

In my free time, I like to go out and enjoy the outdoors, whether its hiking, snowboarding, or fly fishing.
