Dr. Crystal Tulley-Cordova, PhD, MWR is a Principal Hydrologist in the Navajo Nation Department of Water Resources - Water Management Branch. She received a doctoral degree in Geology and an Interdisciplinary Graduate Certificate in Sustainability from the University of Utah. She has received a Master of Water Resources in Hydroscience and a Bachelor of Science in Earth and Planetary Sciences from the University of New Mexico. She has worked collaboratively with Navajo Nation partners on water-related research since 2013. Her research interests include learning more about the Navajo Nation water budget, namely the interactions of precipitation, surface, and ground waters, and the nexus with Navajo communities.
Her past research consisted of three projects conducted in collaboration with the Navajo Nation Water Management Branch, Navajo Tribal Utility Authority, and Navajo Environmental Protection Agency; they are entitled (1) Navajo Nation, USA, Precipitation Variability from 2002 to 2015, (2) Stable isotopes in precipitation and associated waters: Recording the North American monsoon in Arizona, New Mexico, and Utah, and (3) Groundwater sustainability and susceptibility to modern contamination in Fort Defiance, AZ.
Crystal has a passion for working with tribal communities. She realizes the importance to help tribal nations dependent on water resources understand the effects of hydroclimatic changes on their tribal homelands. Crystal hopes the knowledge and experiences she gained over the years will help her assist Navajo communities to use their current knowledge about water to build sustainable water projects, seek funding for water-related research, and protect and manage water resources across the Navajo Nation.
