His research advances multi-objective decision making and model diagnostics for engineering problems. Areas of focus include water resources planning and management, environmental engineering applications, and advancing methodological contributions to decision making and optimization under uncertainty. Current research projects in his group include creating a framework for improved water quality under extreme climate events, incorporating hydrologic forecasting for water resources management in Chile, robust decision making for the Colorado River Basin, and developing a novel decision support framework for creating sustainable building materials. Recently his group completed an extensive project to assess how optimization can be used for water resources in the Front Range of Colorado, in collaboration with key stakeholders.
