Education
Chief earned her B.S. and M.S. in civil and environmental engineering at Stanford University. She completed her PhD in hydrology and water resources at the University of Arizona in 2007, where she is now a faculty member.

Career
One of Chief's research interests is addressing food, energy and water challenges in Indigenous communities with methods that include their traditional values. In particular, she has researched the impacts of the 2015 Gold King Mine spill on residents of the Navajo Nation. Her research regarding the effects of the Gold King spill have aided several communities affected by the disaster. As part of this work, Chief gives public presentations in the Navajo language, especially to farmers, ranchers, and families who are affected by pollution and mining waste. She has said that her scientific research and her identity are closely linked, telling Science Friday, “my identity is water-based [from the Bitter Water Clan]. And so that motivates me to do the work that I do.”

Chief was featured in a short film produced by Science Friday in 2018, and is one of the interviewees in the feature documentary Hacking at Leaves.
