He also has a joint appoint at the Utah Water Research Laboratory. His work uses systems analysis (optimization and simulation modeling and data management) for water and resources management, infrastructure expansions, demand management, and conservation at scales ranging from individual water users to regional systems. His work integrates engineering, economic, environmental, uncertainty, and when necessary, social and political considerations to plan, design, manage, operate, and re-operate water systems. Applications include optimization for environmental purposes, water conservation, computer support to facilitate conflict resolution, supply/demand modeling, and portfolio management to minimize risk. He has worked in the Middle East, Calif., Maryland, and now Utah.
