With a double Master’s degree in Urban Services and Human and Social Sciences, Lise-Ella specializes in improving access to essential services in ‘developing countries’. She joins Global Development in 2019 to contribute to water, sanitation and waste projects. Since 2022, she is also our ‘waste’ thematic referent.

As part of our Global Development group, Lise-Ella manages international projects with varied budgets, and she is involved in their institutional, organizational and socio-economic aspects. Her expertise in participatory social engineering methods enables her to work with a variety of audiences (institutions, operators, communities, etc.) to develop concerted studies and recommendations, thus ensuring the realism and viability of proposed solutions. She also promotes an inclusive and resilient development approach in every project she undertakes.

Her career path has led her to specialize in the solid waste management (SWM) sector. She has carried out several waste characterization studies (Latin America, the Caribbean, West Africa), participated in studies aimed at strengthening pre-collection services in urban areas (Central Africa, West Africa) or promoting integrated waste management (Latin America). She has also taken part in the development of international best practice guides for waste prevention, management and recovery, placing the gender issue at the heart of the approach (Maghreb).
