Srinivas Marmamula received his initial optometry training at L V Prasad Eye Institute and then completed his Masters in Community Eye Health from the London School of Hygiene and Tropical Medicine, University of London, with a joint sponsorship from the Department for International Development (DFID - UK), British Council for Prevention of Blindness (Boulter Award), and LVPEI. In 2011, he completed his PhD from the School of Optometry and Vision Science, UNSW, Sydney with support from Vision CRC, Australia. Dr Marmamula undertook his post-doctoral research fellowship (2012-2013) with Dr David Friedman at Wilmer Eye Institute, Johns Hopkins School of Medicine, Johns Hopkins University, Baltimore, USA. He was the Chief Optometrist for LVPEI’s landmark studies, Andhra Pradesh Eye Disease Study (APEDS, 1996 – 2000), and Refractive Error Study in Children (2000) supported by the National Eye Institute and World Health Organization. Currently he is a co-investigator for the follow-up of Andhra Pradesh Eye Disease Study (APEDS III). He is also the faculty for the Master in Community Eye Health course offered at GPR ICARE, and for the BS Optometry course offered at Bausch and Lomb School of Optometry.

Dr Marmamula is the recipient of the prestigious Wellcome trust / DBT India Alliance Early career Fellowship (2015), for a research project on visual impairment in elderly populations. He has also received many international travel grants and has participated as faculty in many workshops in India and abroad. He has over 50 publications to his credit in peer reviewed journals. His areas of interest include: epidemiology of visual impairment, refractive errors, presbyopia and training personnel for community eye care, eye health in elderly and vulnerable populations.
