Research Interests & Background
Dr. Colby’s research, teaching, and outreach focus on economic tradeoffs in water and energy management, climate change adaptation, and incentive-based agreements to improve water supply reliability for agricultural, environmental, and urban needs. Colby has provided invited testimony in her areas of expertise to state legislatures, state and federal courts, and the U.S. Congress, and has taught at Harvard University’s Kennedy School of Government Executive Training Programs. She works with western states, federal agencies, private firms, water districts, and NGOs to develop and implement new strategies to improve water supply reliability and resolve conflicts over water. Dr. Colby has authored over one hundred journal articles and eight books, including Risk And Resilience: The Economics of Climate, Water, and Energy in the Arid Southwest; Water Markets in Theory and Practice; and Braving the Currents: Resolving Conflicts Over the Water of the American West. She recently was awarded the Warren Hall Medal by the Universities Council on Water Resources for distinguished contributions on water research and public service.
