David Grey is a practioner with over 35 years experience worldwide in inter-sectoral water assessment, management and development. He joined Oxford University as Visiting Professor of Water Policy in late 2009 after 26 years as staff of the World Bank. He was the World Bank's Senior Water Advisor from 2003, with responsibility for corporate water policies and advisory oversight of the water community of 400 staff and the portfolio (c. $40 billion) of water resources, irrigation, water supply and sanitation and hydropower. He is a water policy analyst, researcher and writer and he is a manager of large, multi-disciplinary, multi-national teams, controlling large budgets.

His current special interests are in: the roles that water insecurity plays in poverty, environmental degradation and dispute and water security plays in growth and stability; the role that benefit sharing can play in resolving inter-jurisdictional disputes over water at all levels; and the risks that climate and other change mean for water security, livelihoods and environmental sustainability. He has a long-term interest in the institutional and incentive structures for improving the performance of water and environmental management and water service delivery.
