I am currently working as a lecturer (Unconfirmed) at the Department of Zoology of the Faculty of Natural Sciences in the Open University of Sri Lanka. I gained my B.Sc. (Hon’s) degree in Zoology, with a First class from the University of Ruhuna.  I completed my M.Phil. degree at the University of Ruhuna in 2023 by conducting a research study in the field of Environmental Health which is mainly focused on the identification of an early detection tool for renal injury among adolescents living in chronic kidney disease of unknown etiology (CKDu)-endemic areas in Sri Lanka.
