Karletta Chief

Karletta Chief is a Diné hydrologist, best known for her work to address environmental pollution on the Navajo Nation and increase the participation of Native Americans in STEM.

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.

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. 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.
