Research Fellow
London School of Hygiene and Tropical Medicine

I have an MSc in Control of Infectious Diseases (LSHTM, 2004) and worked at the Health Protection Agency prior to joining the Environmental Health Group in 2007. My research focuses on water, hygiene and sanitation (WASH) related health issues. I completed my PhD in 2012, which involved conducting randomised controlled trials to measure the impact of household water treatment.

I am interested in the design and implementation of impact evaluation studies, trials methodology, epidemiology of diarrhoeal disease and the link between WASH and nutritional outcomes. I have worked in Ethiopia, the DR Congo and lived in India for several years where I was managing a large cluster-randomised trial on the impact of sanitation on diarrheal disease and helminth infections; and a double-blinded trial of household water chlorination.

I am now London-based but continue supporting projects in India and most recently in Rwanda. Current research in Rwanda includes an impact study of community health clubs in Rusizi province and the evaluation of a countrywide campaign promoting water filters and improved cook stoves.
