Brad Sion

Assistant Research Professor, Geomorphology
Brad Sion


Brad Sion is an Assistant Research Professor of Geomorphology at the Desert Research Institute. He has a BS in Geology and Environmental Geoscience from the College of Charleston, and an MS and PhD in Hydrology from the New Mexico Institute of Mining and Technology with a focus on geomorphology and Quaternary geology. Brad began his research career in central New Mexico studying soils and landscape evolution. His research has expanded to areas in southern Nevada, central and southern California, and parts of the midwestern US, and focuses on soil geomorphology and applied soils research. He currently participates in a wide range of research projects that specifically rely on the use of soil datasets to infer landscape characteristics and processes. Examples include vehicle trafficability, surficial geologic mapping, effects of Quaternary climate change on landscape stability, and timing and rates of geomorphic processes.
