Associate Professor Eranga Vithana is a Senior Principal Research Scientist and heads the Ocular Genetics Research group at Singapore Eye Research Institute (SERI). She holds appointments with Duke-NUS Medical School and National University of Singapore (NUS). She has a PhD in Molecular Genetics from University College London, UK and has been working on ophthalmic genetics for more than 20 years. Her current research is focused on understanding the genetic basis of both rare and common eye diseases with Mendelian and/or complex genetic etiology. She has studied the genetic basis and biochemical mechanisms of corneal dystrophies, inherited photoreceptor degenerations (IPDs), all forms of glaucoma (POAG, PACG, NTG, congenital glaucoma), as well as quantitative traits of ocular diseases. Associate Professor Vithana’s research has led to the discovery of genes causative of retinitis pigmentosa, corneal endothelial dystrophies, glaucoma and ocular quantitative traits.
Associate Professor Vithana has published more than 110+ peer-reviewed papers that include highly cited articles in Nature Genetics, Molecular Cell, American Journal of Human Genetics, Ophthalmology and Human Molecular Genetics and has an H index of 52. Grant funding awarded to her as either the principal investigator (PI) or co-PI total over S$10 million to date. She has presented her scientific findings in numerous conference proceedings and has been an invited speaker at numerous Ophthalmic and Genetic conferences. Associate Professor Vithana served as chair in Genetics section of ARVO Annual Meeting Program Committee (AMPC), and participate in scientific program planning committees of World Glaucoma Congress (WGC) and Asia-Pacific Academy of Ophthalmology (APAO).
