Mazdak Arabi, Professor
Dr. Arabi is the Borland Endowed Professor of Water Resources in the Department of Civil and Environmental Engineering (CEE) at Colorado State University (CSU). His research, education and engagement activities focus on the development of scientific approaches and analysis tools that enable integrated water resource management in a changing world. His primary expertise includes hydrologic assessment, watershed modeling, water quality control, and system identification and optimization. He is the creator and currently serves as the director of the One Water Solutions Institute (OWSI). The mission of the institute is to solve real-world water challenges via cutting-edge research and innovation. OWSI coordinates synergistic activities at several multi-institutional research networks, including: Urban Water Innovation Netwrok (UWIN), CLEAN Nutrient Center, and Water and Climate Sustainability Center.
