With a dual Master’s degree in Urban Services Engineering and Human and Social Sciences, Lise-Ella specializes in improving access to essential services in ‘developing’ countries. She joined Hydroconseil in 2019 to contribute to water, sanitation, and waste projects. Since 2022, she has also been our solid waste specialist.

Within our Global Development group, Lise-Ella manages international projects with varying budgets and is particularly involved in institutional, organizational and socio-economic aspects. Her expertise in participatory social engineering methods enables her to work with a variety of audiences (institutions, small operators, communities, informal sector, etc.) to develop concerted studies and recommendations, thereby ensuring the realism and viability of the proposed solutions. In addition, she promotes an inclusive and resilient development approach in each of the projects she is involved in.

She has drawn on her knowledge of public policy to carry out institutional and organizational assessments for central and local government institutions, as well as the private sector (ministries, cities, operators, etc.). Lise-Ella fosters an inclusive and resilient development approach in all the projects in which she is involved.

Her career has led her to specialize in the solid waste sector. She has conducted several waste characterization studies (Latin America, Caribbean, West Africa), participated in studies aimed at strengthening pre-collection services in urban areas (Central Africa, West Africa), and promoted integrated waste management, particularly for the most vulnerable groups such as waste pickers (Latin America). She has also participated in the development of international best practice guides on waste prevention, management, and recovery, placing gender issues at the heart of the approach (Maghreb).
