Dr May Sule is an Environmental Engineer specialising in the interactions between water, sanitation, hygiene and health systems. May has worked and researched on urban water supply systems, water pollution and treatment, and international development. Her research focuses on the technical and non-technical (socio-economic) aspects of achieving water, sanitation and hygiene (WASH) success in line with the global sustainable development goals agenda.

More recently, May's research has been integrating health into water security methodologies and tools as well as improving the delivery of safe drinking water and climate resilient water supplies. Her research further contributes to embedding sustainable water, sanitation and hygiene (WASH) as a control measure in eliminating neglected tropical diseases (NTDs) as a public health concern. She has a keen interest in behaviour change, stakeholder engagement, equity issues and effectively communicating scientific evidence to help inform public policy.

May obtained her PhD in Environmental Engineering from Imperial College London. She was a Post-doctoral Research Associate on the DFID funded project (Future Proofing African Cities for Sustainable Growth) and the GCRF/EPSRC funded project (Water Infrastructure for Schistosomiasis-Endemic Regions) at Imperial College. She was a Senior Research Associate in Water Quality, Climate and Health at the University of Oxford on the GCRF Water Security Hub and the FCDO funded REACH programmes.

May joined Cranfield as Lecturer in Water, Sanitation and Hygiene in June 2021. She is the Course Director for the Water and Sanitation for Development MSc programme and Module Convenor for Public Health, Hygiene and Sanitation.
