Professional Interest/Expertise/Specializations:
I have been the Director of the NEI/DMEI Image Module and the COBRE Image Core for the past 13 years. I am a Professor in the Departments of Ophthalmology and Cell Biology, an NEI R01-funded investigator and Associate Director of the Oklahoma Center for Neuroscience. The overarching objective of my research program is to prevent vision loss using prophylactic and therapeutic agents, and determining the molecular mechanisms by which they act. I think that the excessive increase in toxic Reactive Oxygen Species (ROS) is an ¿Achille¿s Heel¿ for inherited retinal degeneration, Diabetic Retinopathy, Age related Macular Degeneration (AMD) and other neurodegenerative diseases and that by targeting excess ROS for destruction, the downstream damage and disease symptoms can be prevented and/or decreased, vision can be prolonged and the quality of life for such patients dramatically improved. Consistent with this idea, I have developed a research program using rodent models to demonstrate the positive effects of the use of catalytic antioxidant cerium oxide nanoparticles or nanoceria to inhibit pathologic neovascularization and retinal degeneration.
