Biography

Dr. Sampson is a systems analyst and process modeler. David creates and links algorithms (problem-solving instruction sets) that mimic physical, social, and biological processes of interest to students, water managers, and stakeholders alike. These computer simulation tools permit real-time analyses of current and future (probable) events and the physical and social/ political implications (and responses) to these trigger mechanisms (and the potential ramifications). A recent project funded by the National Commission on Energy and Policy, in conjunction with Portland State University, evaluated the expected water and energy use for the Phoenix metropolitan area (and short-falls) under climate change. His current research focuses on the development and implementation of an urban water policy and planning tool labeled WaterSim 5, an open-source software program that can be used by students, faculty, and water resource managers to examine trade-offs in water governance and planning strategies in the face of deep uncertainty (in population growth, climate change, and drought) for central Arizona communities.
