A chartered engineer with a second degree in Development Studies, Professor Barbara Evans holds the chair in Public Health Engineering in the School of Civil Engineering at the University of Leeds.  She leads a multi-disciplinary team that works on sanitation, hygiene and water services in the global south with a particular focus on urban sanitation in cities and towns.  Professor Evans’ career spans 30 years; she worked at the World Bank for over twenty years before joining the University in 2009 and has lived and worked in South and East Asia, Africa and Latin America.  Recently Professor Evans has been working extensively in East Africa with the HyCRISTAL project exploring the intersection of climate change and water/sanitation services planning and delivery.  She provides strategic advice to the United Nations Joint Monitoring Program for Water and Sanitation, the RCUK Grand Challenges Research Fund; the Bill and Melinda Gates Foundation, the Container-based Sanitation Alliance and the Government of India. She has won several prizes but is more proud of the cohort of brilliant early and mid-career graduates of the WASH training programme at Leeds who are now infiltrating government, the private sector and development agencies with a vision of effective modern public health engineering.
