Alistair Barber

Alistair Barber, PhD, is a Professor in the Department of Ophthalmology and Department of Cell and Biological Systems at Pennsylvania State University's College of Medicine. He serves as Associate Research Director for the Penn State Eye Center and previously directed the Graduate Program in Neuroscience (2018–2024). His research focuses on retinal neurodegeneration in diabetic retinopathy and age-related macular degeneration.

Research Interests: Dr. Barber's work investigates how diabetes induces retinal cell death via apoptosis, synaptic protein deficiencies, and neuro-inflammation. His lab established neurodegeneration as a critical factor in diabetic retinopathy, linking neuronal morphological changes to functional vision deficits like reduced acuity and contrast sensitivity. Recent studies explore REDD1's role in stress response and vascular permeability in retinal diseases.
