Visiting Scholar, London School of Hygiene and Tropical Medicine
Research Team

Ruwan is a field epidemiologist with considerable experience in humanitarian contexts and with displaced populations. He advocates for and conducts research to improve the standards of public health for crisis-affected communities. His current focus is on merging field investigation and modern analytical methods to improve outbreak and humanitarian response models. He recently completed a PhD in epidemiology and mathematical modelling as a Doctoral Foreign Scholar at the London School of Hygiene and Tropical Medicine, in collaboration with Epicentre-Médecins Sans Frontières. He evaluated the effects of targeted interventions for cholera outbreaks in fragile settings using mathematical modeling and observational studies.
Prior to this, Ruwan was the Senior Epidemiologist for the International Rescue Committee (IRC), providing technical support in humanitarian settings, primarily in the Democratic Republic of the Congo, Myanmar, Sierra Leone, South Sudan, and for the Syria crisis. He covered multiple areas, as NGO epidemiologists tend to do, including conflict and public health situation analysis, surveillance and outbreak response (Ebola, cholera, etc.), community health and primary care, noncommunicable disease management, and mortality estimation. He was also the Editor-in-Chief of Conflict and Health. Ruwan has also worked for the World Health Organization (WHO) in Haiti and South Sudan, International Organization for Migration in Vietnam, and he trained as an FETP fellow with the Canadian Field Epidemiology Program of the Public Health Agency of Canada.
Ruwan has published widely both research and public health guidance, including recently on cholera in The Lancet Infectious Diseases and on guidelines for early warning alert and response systems in emergencies for the WHO. In addition to his PhD, he has a MHS from the Johns Hopkins Bloomberg School of Public Health, and a BSc (Hons) from the University of Toronto.
