Structural Biology & Bioinformatics

Research Focus

• Identification and validation of the potential genes involved in early diabetic retinopathy by Integrative single-cell analysis. • Dissecting cellular crosstalks and molecular pathways involved in the neurodegeneration process of the diabetic retina. • Developing a liposomes-based nano-delivery system for the treatment of retinal eye diseases • Systems biology approach for early prognostic/diagnostic biomarker discovery

Research Interest

Our lab is interested to understand the pathobiology of retinal eye diseases, particularly Diabetic retinopathy (DR), which is one of the leading causes of blindness globally. The molecular mechanisms involved in the development of early diabetic retinopathy are not fully understood. Hence, our lab is interested in dissecting the underlying molecular mechanisms of early pathogenesis of diabetic retinopathy, which can help identify targets for intervention to prevent or slow the progression of diabetic retinopathy.
