Water resources management integrated assessment system dynamics irrigation urban systems
My primary interests lie in the fields of water resources planning and management, systems thinking and modelling, and sustainable development.
My research focuses on water resources planning and management, and in particular understanding and modelling the complex feedbacks among water availability, use, and quality, and their larger social, economic, and environmental context. Most of my work develops and applies hydrological, water use, and water quality models to 1) identify and clarify cause-effect relationships in water resources systems at municipal or river basin to global spatial scales, and at daily or weekly to decadal time scales; and 2) produce and apply computer models and indicators in collaboration with decision makers and stakeholders to compare structural, management, and policy alternatives. The work is important because sustainable planning and management of water policy and infrastructure requires a clear understanding of the problem to be solved, important risks and uncertainties, and the comprehensive “big picture” effects and potential trade-offs of alternative solutions.
Some recent and ongoing projects with collaborators and my graduate students include:

Teaching involves “intangibles” related to passion, curiosity, and openness. We can see many of the “classroom phenomena” in action in the world around us, and I find joy in understanding the world a little better as a result of teaching – a joy I strive to impart to my students.
As professors, we are blessed with the dual role of educator and researcher. While research is often conducted either individually or in small teams, teaching is both social and interactive. We are fortunate to meet new, enthusiastic students each year and through them witness the process of personal growth and rediscover the fascination of new ideas.

Related Lab experiments. The course focuses on key topics in natural resource management and modelling: sustainable development, systems thinking and modelling, and risk and reliability analysis. Specific applications may include examples from sustainable forestry, water resources management, mining, the energy sector (and particularly the petrochemical industry), and municipal infrastructure.Winter Term 2021
