A Canadian engineer and economist by training, Elizabeth’s first WASH job was building toilets in rural Mexico. Her doctoral research addressed incentives to increase sanitation uptake in peri-urban South Africa, and she spent five years as a lecturer at the University of Blantyre, in Malawi. Currently, she is the Chair of Global Health Engineering at ETH Zurich where her group addresses the environmental and human health impacts of WASH service delivery in rapidly urbanising African cities.
