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 consortiums, including: Urban Water Innovation Network (UWIN), CLEAN Nutrient Center, and Water and Climate Sustainability Center. Dr. Arabi is also the creator of the open-source software called environmental Resource Assessment and Management System (eRAMS, see erams.com). Funded by numerous projects from the NSF, USEPA, USDA as well as local and state agencies, eRAMS enables development of computationally scalable and accessible online tools for sustainable management of land, water, and energy resources. eRAMS and its cloud services implantation platform (CSIP) currently host to more than 400 data, analytic, and modeling web services that are used by researchers, U.S. federal government agencies, state and local governments.
