Dr. Layla Hashweh, a Palestinian raised in Jerusalem, has worked with different international organizations, and has several years of experience in the private, public, and NGO water sector in Palestine, Israel, Jordan, Europe, East Africa, Zambia, Ethiopia and South Africa.

Layla has a strong interdisciplinary background as she received her BSc in Agricultural Economics & Management with a minor in Environmental Studies from the Hebrew University in Israel. She then pursued her master’s degree in Hydrology and Water Quality working on the rehabilitation of a transboundary polluted stream at Ben Gurion University. Layla did her PhD in Hydrogeology with the Center for Development Research in Bonn, Germany, as part of the global food security initiative GlobE project ‘wetlands in East Africa’, focusing on the modelling of the endangered Ewaso Narok floodplain in Kenya. Layla spent the last two years working as a proposal manager for an engineering team, ensuring suitable country-specific design of water and wastewater systems. Layla is fluent in Arabic, English, and Hebrew, and has a high command of German.
