Jack Sieber is a Senior Scientist and the Deputy Director of SEI-US.

Jack develops computer-based tools to assist in long-range scenario planning, and working with researchers, policy makers and other stakeholders to help build a path to a sustainable future. Currently, his work focuses on integrated water resources planning at the watershed scale, with a special focus on the potential impacts of climate change.

Jack is the developer of WEAP, the Water Evaluation And Planning system, a leading integrated water resources planning tool used by hundreds of organizations worldwide.

Jack received an M.S. in Computer Science from Yale University in 1988.
