Research Focus

Gene therapy for diabetic corneal stem cells. Generation of corneal epithelium from iPSC for limbal stem cell deficiency therapy. Inhibition of protein kinase CK2 to block pathological retinal angiogenesis. miRNA in normal and diabetic cornea.

Research Contributions

Discovered markers of diabetic keratopathy and normalized corneal epithelial stem cells by gene therapy. Develops new methods for corneal cell generation from iPS cells. Uncovered the angiogenic role of protein kinase CK2 and used combination therapy against pathological retinal angiogenesis.

Current investigations include:

Gene therapy for diabetic keratopathy using organ-cultured corneas with focus on stem cells. Generation of corneal epithelium from iPS cells for limbal stem cell deficiency. miRNA changes in diabetic corneas.
