My research focuses on the epidemiology of disease related to water, sanitation and hygiene (WASH) and the design and evaluation of WASH interventions to control these diseases.

Currently, I am based in Kenya as Visiting Scientist at the International Institute of Livestock Research. Here I coordinate a multi-country study of foodborne disease among children from low-income urban areas of Nairobi, Kenya and Maputo, Mozambique and the development of a comprehensive intervention to address this disease burden. Prior to this, I led the design and evaluation of a novel handwashing intervention - Surprise Soaps - for children in humanitarian camps in Myanmar and Northern Iraq, an intervention we are now testing on a larger scale in Somalia and Sudan.

I also support the design of research tools for a number of other WASH projects and I am particularly interested in mechanisms of health-related behaviour change among children, a topic which forms part of my ongoing PhD work.
