Speakers
Payton Gardner
Associate Professor at the University of Montana, in Missoula, MTMr. Gardner is a hydrologist and geophysicist who studies how water moves underground through mountains and landscapes. As an Associate Professor at the University of Montana, his research focuses on understanding where water comes from, how long it stays underground, and how it connects to rivers and ecosystems. By combining field measurements, natural chemical tracers, GPS-based earth measurements, and computer modeling, his work helps shed light on these hidden groundwater systems and improve predictions of water availability. His research is supported by the National Science Foundation, the U.S. Department of Energy, and the U.S. Geological Survey, and his findings have been published in leading Earth science journals.
