As a medical parasitologist with focus on neglected tropical diseases, my current expertise is in epidemiology and control of schistosomiasis (300 publications on WOK, >9000 citations, h-index 50, average citation per item 30.4), undertaking multidisciplinary studies from molecular diagnostics to applied social science.

My research has often translated into several WHO policy changes. I have presented, co-chaired and chaired several WHO expert committees of WHO Head Office/African Regional Office and assisted in WHO Guideline Review: Schistosomiasis(link is external)(opens in a new tab).
