Doran Spencer, M.D., Ph.D.

Assistant Clinical Professor

Dr. Spencer is a Retina specialist who focuses on uveitis (inflammation of the eye) as many forms of uveitis affect the retina. Dr. Spencer obtained a PhD in Immunology in Portland, Oregon in conjunction with his medical degree where he focused on animal models of uveitis and helped identify novel therapeutic targets for treating eye inflammation. As an ophthalmologist, he has trained at the following institutions: UC Irvine, Harvard Medical School and UC San Diego. He has been with JRC for the last 2 years as a faculty member. Dr. Spencer works closely with Rheumatology and other medical specialists to help control this condition. Beyond this, Dr. Spencer is a Principal Investigator of a clinical trial involving new eye-drop therapies for uveitis affecting the front of eye. He also is a faculty member of the San Diego VA hospital where he works with UCSD faculty, residents and retina fellows.

Nicholas Oesch, Ph.D.

Assistant Research Scientist of Psychology

More on Dr. Oesch at oeschlab.ucsd.edu

Retinal Neurophysiology Laboratory

Dr. Oesch’s laboratory studies how retinal neurons communicate with each other to process visual information, using whole-cell electrophysiology, optical physiology, and behavioral techniques. Dr. Oesch collaborates with the Jacobs Retina Team on many studies to understand how retinal disease alters the physiology of retinal during disease, and how therapeutic strategies can restore neural communication in the retina.

The current focus of Dr. Oesch’s laboratory is investigating how synapses between retinal neurons extract contrast information during dim light vision. He is also working to understand how retinal prosthetics activate retinal neurons, how neuroprotective therapies restore function in glaucoma, and how stem cell-derived
retinal neurons communicate and function.
