Description of Clinical Expertise

My clinical research is focused on finding new biomarkers for Age Related macular Degeneration and hereditary retinal degeneration (Stargardt and Best Dystrophy), using multimodal imaging and functional analysis.

Description of Other Expertise

My translational research is focused on finding early systemic biomarkers in patients with Age-Related macular degeneration.

Description of Research Expertise

My basic research is focused on evaluating the basic mechanisms involved in the pathogenesis of Age Related Macular Degeneration. I am evaluating signaling pathways that have a role in RPE apoptosis and photoreceptor degeneration.
