I have led several projects on generating evidence based recommendations for diagnosis and treatment of neglected tropical infections such as malaria, dengue, leptospirosis, toxoplasmosis, tetanus, typhus, snakebite and leishmaniasis. I am also an author affiliated to the Cochrane Infectious Diseases group at Liverpool School of Tropical Medicine. I serve as an associate editor for Cochrane Clinical Answers since 2016. I organized (and participated as a resource person) a workshop on writing Cochrane reviews for the staff of Faculty of Medicine, University of Colombo, Sri Lanka in 2017 for peer capacity building, in collaboration with colleagues at University of Colombo, Cochrane South Asia and Cochrane Caribbean. I played a key role in the massive and successful public health effort of malaria elimination in Sri Lanka (certified as malaria free by WHO in 2016). I currently run a prospective cohort study on Dengue infection as a principal investigator in collaboration with University of Colombo, Sri Lanka. Given my expertise on the topic I have been a peer reviewer for many journals, and serve as an associate editor for PLOS Neglected Tropical Diseases, BMC infectious Diseases (formerly) and Systematic Reviews. I have organized and chaired sessions in infectious diseases conferences and delivered lectures / seminars / orations by invitation. I maintain an h-index of 32 and over 3200 citations, and was ranked within the world's top 2% of scientists in the discipline of tropical medicine by citations in 2020.
