Marion graduated from the University of Montpellier with an engineering degree (Master) in water sciences and from Cranfield University with a master's degree in WASH (Water, Sanitation and Hygiene). Marion has extensive experience in the field of hydraulics. After beginning her career in the construction of water treatment plants, she coordinated several WASH projects in Latin America and the Caribbean. She then worked as a water treatment engineer on drinking water distribution and sanitation projects in various countries in Africa and the Middle East.

For the past three years, she has focused on the design, evaluation, and improvement of solar-powered water supply systems, developing solutions tailored to the needs of local populations and constraints. Her expertise encompasses the optimization of hydraulic and energy performance to ensure sustainable and resilient infrastructure.

Now an individual consultant, she supports various stakeholders in the design, evaluation and improvement of WASH engineering projects, putting her expertise at the service of initiatives aimed at sustainable access to drinking water.
