My research focuses on the determinants of water, sanitation, and hygiene (WASH) services and behaviours and their collective impact on health and well-being, with a particular focus on hygiene. My work spans multiple settings, including households, schools, and health care facilities. My current work includes testing the impact of multiple community-based behaviour change interventions on household sanitation coverage and individual health outcomes in Malawi and testing the behavioural and health impact of multiple hygiene interventions in urban Zambia.  More recently, more of my work has focused on the links between climate change, WASH, and health.

I serve as the Scientific Advisor for the Reckitt Global Hygiene Institute and support their research activities across a range of grantees and research projects.

I am the ITD Associate Dean for Research (ADR) with a focus on supporting the implementation of LSHTM's research strategy and supporting the careers of early and mid-career researchers in the Faculty.
