Dr. Sasha Richey McLarty, Ph.D.
Washington State UniversityDr. Sasha Richey McLarty is an assistant professor at Washington State University. Her main interest is in identifying and quantifying the interaction between human and physical systems, with a focus on groundwater and large-scale hydrologic systems. Currently, Dr. Richey’s research combines satellite and in situ observations of hydrologic systems into modeling and decision support frameworks over large regional scales, including in the Columbia Plateau Aquifer in the Pacific Northwest (USA) and in Central Asia. She mainly focuses on complex groundwater systems, where interdisciplinary approaches are necessary to understand both natural and anthropogenic drivers of aquifer change. She enjoys working at the interface of research and water resources management and has contributed to multiple “science diplomacy” efforts in the United States and internationally to advance the role of scientific research in decision making. Dr. Richey earned her M.S. and Ph.D. degrees in Civil Engineering – Hydrology and Water Resources Specialty from the University of California, Irvine.
