I am an environmental engineer researching the links between water, sanitation and hygiene (WASH), the environment, and health. I hold an ITD fellowship at LSHTM, where I am expanding my work on climate-sensitive disease control with a particular interest in integrated vector management in agricultural settings. My research increasingly focuses on vector control in rice fields and nature-based solutions that can be applied in both high- and low-income settings.
As part of the Environmental Health Group at LSHTM, I lead a research project investigating how extreme rainfall influences schistosomiasis transmission in Madagascar. I also coordinate two large clinical trials: TISA in northern Senegal and SaniVac in Mozambique. TISA, conducted with Action Contre la Faim, evaluates whether a simple WASH kit can improve recovery rates among children with severe acute malnutrition. SaniVac, in collaboration with INS-CISPOC, assesses the impact of a sanitation intervention on child health and oral vaccine effectiveness in dense urban neighbourhoods of Maputo.
I completed my PhD at Imperial College London as part of the WISER project, in collaboration with Addis Ababa University, the Natural History Museum London, and the National Institute for Medical Research Tanzania. My doctoral research focused on the effectiveness of water treatment processes against schistosome cercariae. I hold a Bachelor's degree in Agricultural Engineering from McGill University and a Master's in Environmental Engineering from Imperial College London.

Teaching
At LSHTM, I am a module organiser for the WASH and Health module, and lecture on the MSc in Climate Change and Planetary Health, Diploma in Tropical Nursing (DTN) and Diploma in Tropical Medicine & Hygiene (DTMH). I also give a number of guest lectures on WASH and health, including at Imperial College London.
I supervise six PhD students: Nina Finley (LSHTM, Aberystwyth & Natural History Museum), Amelia Rupp (Imperial College & LSHTM), Lara Moussa (LSHTM & Birkbeck), Hiroaki Tomoi (LSHTM & Nagasaki), Jessica Brocklebank (Cardiff & LSHTM), Brenda Kisia (Aberystwyth & LSHTM), focusing on research in schistosomiasis, WASH, malnutrition, and climate change.
Research
My main research interest is the link between water, sanitation and hygiene (WASH) and neglected tropical diseases, particularly schistosomiasis, and how climate change influences transmission dynamics. I am also increasingly focused on integrated, agriculture-linked solutions for vector control in rice-growing settings. This includes nature-based approaches that bring together water, climate, food systems and health in both high- and low-income contexts.
